Vespa LX Carburetor Rebuild 

So far, thanks to you, I've been able to rebuild my carb on my GT200, change my rear brakes and change the rear shocks, since things were already taken apart, and get everything running correctly. I've met you a couple of times in San Diego and you have always been really friendly and helpful. Your videos are very much appreciated and make it easy to work on these machines. THANK YOU!!!! can't say it enough.

Great video, as always. One thing to keep in mind is that if you own anything that's carbureted (i.e., motorcycle, scooters, lawn mower, etc), using ETHANOL FREE FUEL really helps to eliminated any issues with a Carburetor.

Thanks to Mr Robot, i have rebuilt my old trusty Et4 125 1998 old engine model. You are a gem! Your channel is my go to source for all my Vespa issues!

Super helpful video! Couple things I learned that can be helpful. 1. Make sure the diaphragm spring is in correctly as it tends to want to go off center and bind. If it's wrong your acceleration will be poor (like a torn diaphragm) since the slide won't be able to raise up very far as the spring binds up which won't allow the metering needle to work properly. 2. As Robot says if you have a drill with an impact setting it can be very helpful with removing the easy to strip screws on float bowl and diaphragm housings. I just set it to the lowest impact setting and then it easily freed the screws in a couple of seconds.

Thank you for awesome video! Mr. Robot

You rock Robot! Thanks to all your vids I've got three lx150 on the road running. I was able to get a gy6 carb to work but the Keihin is the way to go.

Excellent 👍

Thks four your excellent video I have a Vespa Lx 50 my carburetor drope a little petrol from the bolw if I remove the carburetor to change the tray is not out of tune

Wait with the section where you pulled out a little piece with your wooden Q-tip, you said you were going to tell us that orientation and how to put it back in, but it wasn’t part of the video,! Mine fell out and I don’t know how to put it back in😅

Great video,, but mine must of been blocked to the max as replacing jets cleaned it four times still no power, so it was either a new carb or ultra sonic cleaner. So opted for the new carb just plonked it in connect it up and ran like a new bike from the off and the carb had it's factory setting just the stress free option

nice video, suprised you didn't show cleaning the body, spraying out ports. and also assembling float with needle.

thank pro. 😀

Hey Robot i have a 2002 piaggio liberty 150cc engine number m221m . I think is a leader engine (new zealand new) which i am rebuilding ,is this carb similar to the one i have (looks similar) and do you stock the oem carburetor? Thanks keep the videos coming very helpful

on my vespa 2006 lx, my slide and diaphragm won't come out, is this a sign of major issue?

How UNH does a new car how much does a new carb cost ?

Thank you

Hi, can i substitute the lx diapraghm rubber with other model like zip 100 or liberty? Thanks

Hi Robot, how do I convert a 2010 GTS 300 to run with a carburetor??

Hello mr Robot , I’m following your videos for a while now , and today a problem occurred on my Vespa 300 gts hpe 2020 notte (6000km) that I can't solve ; My vespa was working perfectly well, after a stop I wanted to restart ... impossible, the starter works the engine too but does not engage, it is not powered, no spark at the spark plug even after changing it After a check to the odb tag nothing to report. Something is blocking the ignition I have only the blue key and not the red/violet one Is it a problem of anti-theft key or electronic blocking? Have you already encountered this problem? Do you have an idea ? I from France and you are the only person with videos explaining the breakdowns and mechanics vespa ! Thank’s you 🙏🙏

En español no tienes nada? 😊

HELP PLEASE!! My LX150 was running just fine and now after putting gas in it it doesnt run good at all. It bogs out when I try to give it gas, anyone know what I should be looking for? This is 2006 but only has 1400 original miles on it. It looks brand new! Was a great find on craigs list but I think I broke my new toy :( help please someone. I am a girl if that helps, single even LOL sad but true.

Shit, my '06 runs like a swiss watch!

JIS screwdiver.

One of the most over complicated carbs for such a small bike, diaphragm tech is always problematic I wish they had just fitted it with cable slide
