Something to be extra mindful of when taking apart the E series carbs is making sure to keep track of the super tiny rubber tip that goes on the needle valve. If it ever pops off (doesn't take much for it to pop off) you'll likely never see it again. Your needle valve will not work properly without that tip so you might as well replace the entire carb because a replacement needle valve is only a few bucks cheaper than the entire carburetor

@neilpatrickhairless 4 месяца назад

By the way, this applies to the ones with plastic needle valves - not sure if the metal ones like the one in this video have a tip that can pop off as easily but I would be cautious and handle the needle valve over a container or something that could catch the tip if it did pop off.

@VintageEngineRepairs 4 месяца назад

Great video, thank you for making and sharing. One thing that shocked me though, is to see that even lawn mower manufacturers are now using cheap plastic parts to build. Disgraceful when you think about it. Plastic parts are cheaper to make, break down faster/or more often and the lawnmowers cost same if not more than the mowers made back in the day using non plastic parts.

I have a Honda mower, it was surging & kinda struggling when going over tall grass. I took apart the carb & used the seafoam intake cleaner that comes with the red straw to sprayed the crap out of it & used the straw to put pressure through all those fine holes you pointed out. Put it back together and & added a bit of the seafoam you add to the gas tank as well. Problem solved, put new blades as well & that puppy is purring nice & now I can go over tall grass without stalling. And that was my 1st "taking a carb apart" job lol, glad I didn't wreck it! 😂

@waynestefinashen239 9 месяцев назад

Tom one of your best videos very informative and well put together. These carbs are a pain but good for business here in Canada. The jets are so small just a small piece of debris that gets through the fuel tank screen is enough to make it run poorly, hunt or not start at all. Those jets are only held in with O rings and if you ever get one that is flooding ie: low rpm and black smoke the jet has loosened off and fuel is bypassing the O ring. I know this for a fact when i kept using carb cleaner with the straw and was actually pushing the jet back in place without knowing it. Customer would use the machine for a lawn cutting and sometimes into the second cutting and it would flood out again. Not until i ran it in the ultrasonic cleaner did i find the jet falling out and realised the problem. Reinstalled the jet with some SealAll glue around the OD only pushed back in a voila good to go and still running smooth. It was cheaper than replacing the module which runs around $20 Cdn.

@beerggls Месяц назад

Be mindful when removing these carbs from the intake tube that you don’t lose the black o-ring. They can come loose when pulling carburetor off the tube, or stay on the intake tube. There is a white o-ring too. Upon reinstallation, seat the black o-ring into the carburetor first, then the white one, then push back onto lightly lubricated intake tube. Don’t forget to connect your governor linkage pushrod and spring first. If you have a autochoke (common on Toro Recycler), there will be a second pushrod linkage on the choke control arm, which can be tricky trying not to bend and deform the pushrod. Mind that the plastic pusher foot on the autochoke pushrod connection piece atop the carburetor is positioned on the correct side of the choke control arm where the foot makes contact, so as when the exhaust heats the autochoke actuator and actuates the pushrod, the foot pushes the choke linkage to the open position. It is possible to assemble with the foot on the opposite side of the choke arm. A heat gun is a good way to test an autochoke bi-metal actuator for proper operation.

@catseatcheese 8 месяцев назад

Hi Tom, I appreciate the vid. My 3 y.o. Cub Cadet snow blower sat dormant last winter and I forgot about the gas. It fouled the carb, so I drained it and cleaned the carb, making sure every hole, passage etc was squeaky clean. It started on the first pull, but it surges when it never did before. This is a puzzler for me. Any suggestions?

@VintageEngineRepairs 8 месяцев назад

Hey, surging when not under load is a restriction of the idle fuel passage or too much air. Double check any o-rings that can fail too :)

@LandyAndy62 2 месяца назад

You need to check the priming bulb too - they perish and can let air in even when they don’t show any fuel leakage. Top tip for all these machines that are only used seasonally - ONLY USE PREMIUM GRADE FUEL. Many of the E5 Petrol’s are just Petrol - there is no ethanol in many of these premium fuels (UK law states it must be marked and sold as E5 if it has less that 5% ethanol - which of course pure petrol is!) Ethanol causes the petrol to spoil within a few months and destroys many of the plastic fuel lines, seals etc. Nitrile and butile rubbers (O rings) are mostly OK, but plastic fuel line especially will just rot if ethanol is present (yes, I am talking to you Stihl). You do not need to buy the over-priced ‘petrol substitute’, just straight petrol is fine, but do drain it out if you’re laying up the machine for months.

@VintageEngineRepairs 2 месяца назад

Yep use non ethanol is a huge problem solver for many! Thanks for watching 👍👍

@rebeccamills9067 Месяц назад

Great video, very clear to follow. My mower was surging and running for a minute or two then cutting out, I have replaced the carburettor and air filter and it is still surging and cutting out but will run for maybe 4 or 5 minutes now before cutting out. It also requires priming every time to start. There is new fuel in it and no water in the fuel tank. Does this give you any clue as to what the problem may be please? Thanks in advance

@VintageEngineRepairs Месяц назад

Hey, what is the flow like through the fuel line? It may be as simple as a partially blocked fuel filter inside the tank.

@rebeccamills9067 Месяц назад

@@VintageEngineRepairs thank you for the reply, the filter at the bottom of the tank looks clear and I can't see any splits in the fuel line. I think I might have to order some micro drills and have a go at increasing the bore of the air jet.

@HORIZON8026 25 дней назад

I had luck by drilling out the lower main jet because the mower likes to mostly run off the pilot jet it's very starved underload by that smaller main jet down bottom I gained and extra pony in the cut when I went up a size with that main jet ran way better it probably could.go up a couple sizes on these carbs possibly you may need to up both got the micro drill bits off amazon just don't break them off in a pilot jet. I did that to one I can't say if I was forceful or the drill bit wasn't very good to begin with their so tiny

@VintageEngineRepairs 25 дней назад

Yes unless it surges under load, it’s pilot jet :) the drill bits are so easy to snap aren’t they!

I'm working in a honda lawn mower that surges up and down and noticed several things mentioned from your video. I cleaned he carb really good with carb cleaner but the issue still persist. It will start with one pull but not smoothly. it surges up and down still has uneven idle. Things that are red flags to me is the Honda carb is missing several gaskets for instance the one by the air intake and the one by the manifold. They both rotted and deteriorated. Next i notice there appears to be some grime or dirt at the bottom of the tank. I haven't cleaned out and blew out the fuel line. The mower has fresh gas, new plug, new filter. From what i know the prior owner stored it outdoors and looks like it was only covered sometimes not all the time and was exposed to rain and snow in the northeast in the states. any recommendations what to do next to get the mower running smoothly again?
