Always amazing to see how much junk settles out of the fuel. The "blow" method is the best test there is. Tasty, too!

@stephengardin2423 6 лет назад

Martin, I believe you're correct. That junk in the bottom of your catch bottle looked like water and rust. The carburetor will probably have some corrosion built up in the small orifices. The flat spot could also be attributed to a stretched diaphragm. Best of luck and we'll be watching. Thank you.

I just bought this Vespa. Mines a 2003 w 1,400 miles on it and is pretty flawless. However, as much as I want to ride it, I see that the previous owner has a bottle of Walmart 2 stroke oil in the underseat so I'm not going to ride it until I have the proper Motul, Yamalube etc.. 2 stroke oil to run in it. Nevertheless, I loved your video on the small improvements to make on this bike to pep it up (ie. delimit the variation, carb plate etc.). I'll be doing these as well although I'm not sure yet of the proper jet size. The other thing that distresses me about this scooter it the autoluber. I think mine's fine, but I'd really prefer to just mix the gas/oil myself instead of relying upon the auto-oiler. Thanks for your hard work and passion!

@davespooney8472 6 лет назад

You have done a brilliant job on this, she sounds great 👍. Just running a bit rich, needs a tweak, slightly smaller jet (58) or even try the original jet and a good ride I reckon. Check for vacuum leaks but I think you have covered that already. She's nearly there. The brass plate you removed from the carb isn't actually a restriction, on other scooters they are but not these, mine ran fine without it but you might wanna try putting it back in just to see, it's free so worth doing. Can't see the bike being lean with the 60 jet on a standard engine, unless of course you have a major air leak. I have a brand new rubber inlet manifold here, check yours, if it's cracked you are welcome to mine for free. So, check for air leaks (inlet manifold cracks, carb gaskets, vacuum pipes) Put in standard jet or high 50's, consider putting brass plate back in. Strip carb again, check jets and gaskets. Go for a good ride.

@PauC-qo1uq 6 лет назад

It sounds like you have a vacuum leak, which makes the engine run too lean. Or your mixture needs adjusting. I’ve had this problem before, vent in the fuel cap could be blocked. You’ve done Great job Martin, I’m sure you’ll work this minor problem out. 👍

@rodneyfisher1593 6 лет назад

Great video as always iv got a project moped that I'm going to rebuild for fun thanks for sharing this project with us keep the good videos coming

@retrorestore 6 лет назад

I'll sort it Rodney. Maybe tomorrow. Cheers Martin

@TheMrWoodsman 6 лет назад

I would try putting the original jets back in the carb to see if the problem is still there! It’s all a process of elimination! Good luck and please keep us posted.

@retrorestore 6 лет назад

Just uploading vid 19 where all will become clear.

@Jim-ie6uf 6 лет назад

That’s the way it goes, sometimes. 33 yr old Craftsman chainsaw hit the bench today. This is gonna be fun, you can do it Martin!

@patrick103b 6 лет назад

I’ve already done this for a different problem I have the et4 it was flooding through fuel through the engine into the crank case it now runs out of fuel with just less than half a tank as I said in a earlier comment going to fit a external fuel tap and filter as far as I can tell that valve just shuts the fuel off when the engine is off will let you know weather this solves it as far as the flat spot you have that could be the Excelerator pump look for a little valve on the bottom of the carb that is opened when the throttle is opened great videos by the way

@retrorestore 6 лет назад

Fuel flowing into the crank cases can happen if the fuel is finding its way past the float needle into the inlet. Can be the float height or needle valve letting by.

@DAVEEYEINTHESKY 6 лет назад

great video martin it was good going for a little ride with you, hope you get the kinks ironed out without too much of a head ache. i look forward to the next video and as always its a thumbs up from me

retrorestore excellent martin cant wait to see it

@bigdan2766 6 лет назад

Hi Martin. Picked this up of a piaggio forum might help: sounds like incorrect air screw setting if it's at the very bottom if it's around quarter it's the slide. I would start by taking the carb and carb box off check all jets are correct and set right and not worn(slide) put it all back together with new gaskets. If it's still the same after that check the piston rings they may need replacing, poor compression can cause hesitation on throttle response.

@Av987 6 лет назад

I've had the same issue, all be it with a chinese GY6 scooter. In the end I just replaced the carb (was all rusty and dry cracked gasket, may have been a vacuum leak in the carb) and intake manifold as these chinese parts are cheap as hell anyway. That fixed it for me. As for the flat spot. You may want to try filling it up with higher octane gas. Not sure what they have in britain, but I fill it up with 98 instead or 95 and it makes a difference at full throttle.

@Ajt1994 6 лет назад

Good video martin look forward to seeing the problem.

@retrorestore 6 лет назад

So am I Aaron lol

@tegleeds3188 6 лет назад

Hi Martin I had more or less the same problem with a 125 Gilera Runner and after doing all the same things you have done I found the problem to be a small piece of grit underneath the float needle. Hope this helps. Paul.

@robrusticwoodlandproducts6662 6 лет назад

Crap in the fuel tank Haha. Sorry Martin, couldn’t resist it. Atb. Rob.

@retrorestore 6 лет назад

It had to be said Rob lol

@scottygdaman 2 года назад

Well so much for a filter .. a? I'm thinking the filter is intended to prevent diaphragm damage ?

@burtjohnson7298 6 лет назад

Hello martin, have you check the petrol cap breather vent is clear? Best of luck with the fault finding, could try a test run with the cap off.

@retrorestore 6 лет назад

Yes, i'll be doing that tomorrow when I strip it down Burt. Cheers Martin

@tomcornelius8212 6 лет назад

That is what happened with my dirt bike

@ianmedium 6 лет назад

With all the sludge in the petrol perhaps the jets are clogged, I know when I’ve worked on old engines that have had stale fuel stripping and cleaning the carb and blowing the jets through ( in the old days just like you did with the fuel filter but it made you go bluer in the face!) usually got things going again

@scarlett7858 6 лет назад

lighter rollers and try the brass plate in the carb bud worked for me on many of occasions and saves fuel

@peteramberley9952 6 лет назад

Where was the camera mart in between your teeth ? My mrs thinks she recognises your breathing from the phone call 😂

@retrorestore 6 лет назад

Haha Pete, I had my mini tripod stuffed down the front of my coat. I was a bit puffed as I was pushing the scooter for a few hundred yards before it fired up again so the phonecall wasn't me lol

@peteramberley9952 6 лет назад

retrorestore sounded like it was inside your helmet .no wind noise at all lol

@retrorestore 6 лет назад

Yes, I had a separate mic in the helmet Pete

@peteramberley9952 6 лет назад

retrorestore ah that explains it .good quality mic

@matharm78 6 лет назад

I had a bike which behaved like this and it was worn needles... Maybe worth double checking everything in the carb

@wangofree 2 года назад

I wish I could ditch the vacuum gas valve altogether and have the carb float monitor the incoming fuel. I've had to replace this valve 3 x in the last 6 years.

@diesel508 6 лет назад

Ok lee’s waited long enough and so have we. Trans-Am!

@retrorestore 6 лет назад

Had to get this scooter finished first. Trans Am very soon.

@retrorestore 6 лет назад

Thanks Malcolm

@Menditman2014 6 лет назад

Hi it's sort of an off the cuff response, but couldn't you change the carb back to standard then try it. You would then know if it was the actual carb at fault or the changes you made. Anyway I have hassles like that all the time repairing mowers, I blame a lot on the new Chinese carbs I buy, some seem fine some are a pain in the a**e. You'll get there in the end🙂👍

@brianpercival1829 6 лет назад

Compression, gas and spark. I'd like to know what the culprit is too. Sounds and runs well otherwise, looks great too. I SAW BARNEY!

@retrorestore 6 лет назад

I think its the vacuum line to that new unit I fitted Bri. I'll strip it tomorrow. Yes, Barney is fine.

@paulyh4531 6 лет назад

Bombs along alright when it gets going thou , sure you will sort it mate 👍

@jaggass 6 лет назад

Its probably got crap in the fuel tank due to it being stood for a while or simply just crappy fuel.

@andrewmckechnie6058 6 лет назад

i have seen a video that said the exhaust restriction is there to enhance performance , i'd like to know your opinion on this. Personally i think your'e right . But maybe i'm wrong.

@retrorestore 6 лет назад

No, it won't enhance performance. It's there to restrict the gas flow.

@codycheney3401 6 лет назад

What a bummer with the way its running are you certain that you got all of the sedimate out of the tank ? You could try running an auxiliary tank from like a lawnmower or even a soda bottle that is clear that you can see how it is using the gas ? If there is a chance that its gotten any thing left in the original tank it could act that way and the other thing is try going down a couple of sizes with the jet or maybe up some more. There is a lot more that the engine could be needing. When you figure out how much you opened up with the modifications you made. On mine I jumped up 3 sized just from drilling out the exhaust pipe. Good luck I wish you the best !

@retrorestore 6 лет назад

I still think its a vacuum problem Cody, i'll strip it down tomorrow and find the problem. Cheers Martin

@codycheney3401 6 лет назад

It could be a vacuum problem do you have a vacuum gauge that you could put it where you could see it while riding it ? That would be a simple test especially where you have to feather it into going faster ! Best wishes

@Britec09 6 лет назад

Would not like to do 40+ MPH on that little wheel base, bike looks good Martin.

@retrorestore 6 лет назад

Haha Bri, yes, it is a bit twitchy lol

@Cavalier_Steve 6 лет назад

Another great video Martin, shame about the fuel issue on the carb, Is there any screws to set the air fuel mixture? Maybe these need a tweak. Cheers All the best

@BensWorkshop 6 лет назад

Just a thought, but as you have de-restricted it, perhaps the fuel pump arrangement can't keep up with demand.

@retrorestore 6 лет назад

There is no fuel pump Benedict, it' is a vacuum operated gravity system and I think this is the problem.

@BensWorkshop 6 лет назад

The vacuum operated gravity system has a delivery rate like a pump. Your jet is larger so it's possible that it is using more fuel than can be delivered by the fuel system. You could test that by either re restricting it or just driving it at its design speed and see if it's OK then.

@Taliesin6 6 лет назад

My et2 has a 78mm jet in a 21mm carb and stock fuel pump, it has no probs getting enough fuel.

@ajwasp3642 6 лет назад

I was gonna say, it's too rich. Pull the spark plug, and check it. As Malav said, try the original 53 jet. I would then raise the needle (lower the clip) a notch or two.

@stevehill4615 6 лет назад

Hi, it's not clear in your video if the flatspot is present from the start or if it occurs after a period of running, if it's the later could it be the tank breather isn't working causing a vacuum in the tank after a period of fuel consumption (easy to check --- leave the fuel cap loose, see if fault remains), also are you sure the vacuum tap is working correctly, I always thought it shouldn't be possible to blow through the tap (pipe on the side) unless a vacuum was applied (pipe on the bottom) as was the case with the old tap. Tank breather suggestion is not a common fault but neither is it unknown (breather can be in the tank cap or separate on the tank usually with a one-way valve fitted), if you could upload another video of the conditions and symptoms that would help narrow the possibilities of the fault.

@retrorestore 6 лет назад

Just uploading vid 19 Steve where all will become clear.

@lzr32 6 лет назад

leaks from the vac hose or where it attatches to engine cases . the needle with rubber tip that attatches to plastic float could be jamming or not set to let enough fuel in before the float shuts the inlet back off. I used to have a piaggio typhoon with a malossi 172 kit that could do close to 100mph :D haa

@retrorestore 6 лет назад

Wow, that's quick. Yes, i'll be doing that tomorrow when I strip it down.

@simonrawle7885 6 лет назад

id be going for the float height. but wen it dose cut out have a look at the plug to see if its lean

@retrorestore 6 лет назад

Check out vid 19, no adjustment on plastic floats.

@MrBerenguer67 3 года назад

Hi im sory again i need to change my Tap on Piaggio zip 50 2t what i need to do please??? Is any screw or just pull out thank sow much apreciate

@retrorestore Год назад

It should screw out I think

@makeminealarge1 6 лет назад

Have you checked the flux capacitor set up?

@rogeroconnor5182 6 лет назад

did you happen to replace the fuel and vacuum lines by chance? i have seen them collapse internally. i am certain if you can get a mower running after 10 years in the bushes,you will get it figured out

@retrorestore 6 лет назад

I think it is a vacuum line problem Rog, I'll be sorting it out tomorrow.

@robertbills4290 6 лет назад

Hi Martin do you have to add 2 stroke oil on this bike and if so could that be your problem great video mate p.s iI sound like you on my bike lol Cheers Rob

@tomo12345678911 6 лет назад

Change main jet to a 56 clean air filter adjust needle position on carb change the inline fuel filter using the adjustment screws on carb adjust until seems fit is your vacuum pipe secure on carbs trying taking it off and suck you should see fuel flowing into fuel line

@retrorestore 6 лет назад

Don't have a 53 handy but Yes, i'll be doing that tomorrow when I strip it down.

@steventaylor4586 6 лет назад

lighter rollers are needed as on another commet about brass plate in carb try it in and clean carb good luck

@scooterjd 3 года назад

If when I suck on the vacuum pipe fuel comes out does that mean the petcock needs replacing

@retrorestore 3 года назад

That means its working correctly.

@scooterjd 3 года назад

@@retrorestore what if it’s coming out the vacuum hose

@malics69 6 лет назад

I had a two stroke once and was running too weak was ok low speeds but faster it would slow down and nearly stop

Martin, I thought you had she seemed to be zipping along, Sorry but i don‘t have a scooby doo about scooters, Cheers Dave.

@retrorestore 6 лет назад

Yes, it did Dave, it's only some silly setting. I'll sort it. Cheers Martin

@davidlough2182 6 лет назад

thought you had solved it there m8. i am sure you will figure it out though.

@owenroche1 6 лет назад

don't know if this will help but on my 50 the vacuum line goes on the bottom of the fuel tap

@retrorestore 6 лет назад

that is something I changed as before I touched it, the fuel line came out the bottom and I thought this was wrong so I changed it to the vacuum coming out the bottom as you said. It still happened though so i'll be looking at this set up today. Cheers Martin

@ianallen2 6 лет назад

Seems it happens when it is warm. Could be the auto choke is sticking on.

@retrorestore 6 лет назад

It's worth checking.Cheers Ian.

@FU113R 6 лет назад

@retrorestore 6 лет назад

Not yet Dave, will do as i'm gonna strip it all down.

@weldore1 6 лет назад

they usually have little spring clips holding them airtight...hope its not too bad a job after all the work you've put into it. also as other ppl have said..that autochoke could be staying on if its when it gets warm

@MalcOfLincoln 6 лет назад

Now Mate, I know you'll sort it. However you might??? have 2 problems. A bit of fuel starvation but also a weak spark. This has bit me in the arse a couple of times in the past. 100 Kwak in 93. Seemed like a fuel problem, ended up needing a new coil. It's just you said it has a flat spot, spark breaking down under load. Bit of a ride, stops when the coil gets hot. Few minutes later it cools down and fires up again.

@retrorestore 6 лет назад

Thanks Malc, I think you are right with the fuel starvation. I'm hopefully sorting it today. I think the vacuum tube might be the issue and not allowing enough fuel to flow. Glad you liked the t shirt. Cheers Martin

@petefroud5308 6 лет назад

No guess Martin but the crude in the petrol will not help matters trying to to teach your mum to suck eggs lol . As you say another spin in the cleaner will help for sure. Cheers Pete.

I didn't really clean the carb Pete except for a quick spray of carb clean. I'll sort it properly tomorrow.
