Most guys will just dive right in, figuring "What's the most that can happen?", whereas many women of a certain age were not raised to have that kind of confidence around engines. Thanks so much, Robot, for giving this woman the confidence to go for it.
Sadly, we *tell* women they're strong, confident, capable, etc. But we don't seem to *show* them how to be those things. Repeating them as mantras does a disservice to women. The only way is to dive in.
I was here reading the comments last night at my wit's end considering selling my bike Running out of hope, I followed all your steps and with Gods help and Yours Robot my bike is now running better than ever :) thankyou so much made a big difference to my life honestly!!
Thank you so much for producing such an in depth video on the GT200 carburettor. I have the same problem with my scooter through lack of use. This has given me the confidence to have a go at fixing the problem.
I've cleaned and rebuilt more PWK and si carbs for vintage Vespas than I care to think about, but never a modern carb until yesterday. This video gave me the key tricks (accelerator pump & the variable slide, in particular) to get my friend's bike back on the road after he let it sit for a couple years. 😀 Thanks for making it!
thanks to your guide i was able to fix my Gilera Runner VXR 200. the carburator cap on the top was broken, i replaced it with one made out of metal. now its running perfect again. it's the same engine (LEADER 200)
I just bought a 2004 GT 200L with 450 miles on it on Craigslist. The battery is new, and I'm experiencing a weak start, and the bike smells of gas, with no leaks. I'm thinking I'll clean the carb this weekend. I'm so happy this video exists.
Great video, with the clearest explanations and camera work on this subject anywhere on yt, which gave me the confidence to have a go. It was a slight shame that you skipped over the float / float needle part, as that is where the problem was on my carb. I had some gunge blocking the fuel inlet passage that the float needle sits over. I poked it with an .11 guitar string and sprayed carb cleaner through it and now it works. Thanks Robot!
I just replaced all the fuel lines on a 200L. That little line with the clamp was a pain. Now I know it's the fuel tap that is not working correctly. Great Video. Thank You.
you gained a sub here, exceptional work and explanation. I just got my first vespa gt200, and I am halfway through your video for the first time learning crash course, and my brain is bursting with excitement. Looking forward to bringing this side beast back to living condition, you give me home. thanks mah dude. its been ages since ive worked on a moped or scooter. tyty
Absolutely amazing video I have one problem with my Vespa I have been running it without tightening screw near the carburator of the air filter connector pipe and it’s engine oil which I used getting darker so today after watching your video I figured out the problem and tighten the screw of the carburtor and air filter pipe finger crossed I am hoping I have not made too much damage in the engine
You are the best. This is very important, but easy to make a mess. My bike didn't run once because of this. I prefer to leave it to a professional and I delivered him the carburator ;)
At about 44:37 Robot remembers another part(needle jet holder) to be removed. That part is inserted from the other side and is held in position by the MAIN JET, if the MAIN JET isn't removed, the NEEDLE JET HOLDER will not come out.
I've got a problem. Leader 125 2V A/C 2014 Aprilia SR Motard. It was sat for about 6 months with bad fuel and the bike lost power, top speed, acceleration, everything. During this time I had to change the engine and the same problem with that one too. I used the same transmission components and have serviced them all numerous times. I've replaced the spark plug, fuel lines, fuel filter and many other things. The idle fuel speed screw is backed out about 3 to 4 whole turns to compensate for an issue somewhere and I'm 99% sure it's not air leaks because the inlet manifolds are fairly new and tight. I'm thinking about cleaning the carb tomorrow.
Hello! Very detailed and helpful! Thanks! How and where can I see in detail what you press 51:13 - 51:16 I miss the seals inside, there are three channels, how many rings - seal are there?
Fantastic informative video (as are all your videos). My Piaggio XEvo (which has virtually the same carb) was doing the same thing. Starting on tick over but would die after 20 seconds and would instantly die if your tried to rev it. The bike had been off the road for a long time so drained the fuel. My only real problem was the refitting the diaphragm. It wouldn't sit in the recess, each time I got one corner in, the other would pop out, it was slightly oversized, perhaps by age but otherwise OK. Eventually I resolved the problem by fitting the cap and loosely inserting the 4 x screws. I pulled each screw down gently and then with a steel rule I carefully pushed the rubber in all round,. With finger pressure on the cap it slowly settled into place - thought this might help others. I have 2 questions though, 1. Does it need to be water cooled? Could I cap the pipe. 2. What happens if the auto choke has failed. Will it start and run. I can't find an effective way of testing it. Rich
Pliers from Knipex in California???!! Wow, knipex is a very famous brand in Germany, they are tools for life...thanks for your Videos and best regards from Hamburg. PS: We have at least once a year Carburetor icing, specially after start within the first 5 Minutes in Winter.
Great video! I’ve just cleaned my carb and jets as I have been getting bogging in high revs which I think is a lean condition. She idles ok but can’t figure out what else it can be? My vacuum hoses have been changed, my manifold is new, and air filter sponge is pretty much new too. Can anyone tell me what else it could be and why I’m still getting this issue? Going to change my spark plug again as I have been told this could also be the issue. Any help is appreciated.
Hi there, Gt200 2004,fuel leaking from carb accelerator pump. Seems the pump plunger has worn the pump bore of the float bowl and fuel is leaking past the pump plunger out of the carb ...is there a workaround?
Hi Dr Robot, When I was cleaning my carb on my Fly 150 I didn’t notice the needle guide that is beneath the main jet… I have been having some bogging on full throttle and I wonder if that is the case? I have no idea where to find that part to purchase… any ideas would be much appreciated! Logan
i have big problem with my gilera runner st200 2011 model curb cvk30 at a steep accelerate its tent to cut off , i change everything curb, pipes, fuel bump, union pipe and spark but nothing i try in all positions of mixture 2/ 2.5/ 3 rounds open but nothing can you please help me ??????? the bike has only 17000 km . Thank you.
great video !! i have a 2017 50cc Vespa premavera, it's carburated. lately i have problem cold starting it, it takes several try to start, once it start and run for about 1 minute, when i shut it off and i try to start it again it starts fine.... when it's warm it starts fine but when it's cold it won't start. i've followed your video and i cleaned the carburetor but still same problem 😭. any ideas what maybe the problem? thanks
Hi iven been having a bogging problem with my piaggio skipper st, when i hold the throttle all the way open it starts bogging out and chugs, and tips you may have to fix it, thanks in advance
Dammit! I unscrewed the autochoke, than the intake manifold and exhaust, then moved the carburator but forgot about the autochoke. Now the spring and pin are appart, and i cant find any info on how to put it back together :S Can somebody help me? nice video by the way! I learned a lot but didnt pay enough attention to what i was doing like an i...
Hi! First of all thanks for the video! I have GT2000 Y2004. I'm wondering if you have a video about fixing or changing the fuel level indicator in the fuel tank or one in the speedometer? After not using my Vespa for five months the indicator is not showing the fuel level. Do you have any suggestions? Thanks in advance!
Uldis Freidenfelds I own and maintain a 2005 GTS, first year model of liquid cooled GTS imported to the US. It has been a great scoot when I’ve had time to ride. I joined VCOA this spring. I’m on Facebook too. Perhaps we can help each other with our bikes.
2012 vespa GTV 300 .coolant level dropped ..fan came on ..filled coolant and the fan still runs after quarter mile. ..what could be causing fan still to run?
My 07 GT200 idled/ran great until the last fuel fill up. Now after sitting for a day, it tries to start, then stalls, and won't start at all now. Bad gas?
Hiya Robot, i have a Leader engine piaggio and a problem with it , starts up fine, runs fine but after its switch of for 5 mins it will not start again, you have to wait for atleast 30/40 mins before it fires up again. valves are to spec , new inlet manifold , new auto-choke, new airfilter. my english mechanic is saying i should buy a new carb , but there seems to be nothing wrong with this carb apart for the not wanting to start when motors warmed up , any ideas what it could be as you are a vespa mechanic and my mechanic is not . ?
Thanks for some great videos, Robot! I have a question: there's a ground wire attached to the chassis/frame on the left side. I just found out that mine is not connected to anything. Where does this go?
@Vespa Motorsport: what kind of technique do you use when replacing the old fuel line? How do you get the new hoses firmly sit on the carburetor/fuel tap/fuel filter? Do you heat them up somehow or use somekind of special tool to temporarily enlarge the diameter a bit?
Hi! I have the same carburator. I clean it everything is fine. Chech the automatic choke it working, the needle was moving out.... but stil dont have the high rpm when starting cold. When is out worm outside i cant start the engine, to much fuel, then i must take out spark plug and crank to push fuel out. Float level is set like in video. What can be the problem?
Just remove the vacuum petcock under the right side plastic trim panel, with a large funnel under it, and ALL the gas will drain out. One big issue with ALL motor vehicles, including Vespa scooters, is ethanol gas. It can destroy every single rubber and plastic part in the fuel system, rust the steel parts, and corrode the aluminum parts. Before ethanol, carburetors would just get gummed up. Now things are MUCH worse. I removed one float bowl, and found what looked like a rusty SOS pad in there. It was a steel float bowl. The carburetor was ruined.
Carburetors ARE a lot better, and 10 times simpler than EFI. EFI, and all it's related electronic parts, sensors, fuel pump, ECU, etc are a real nightmare. I have a 2006 GT200, have owned it 7 years, and have NEVER had carburetor problems with it. I only ride it about half the year, here in Phoenix, AZ it is simply too hot to enjoy riding in the summer. When I put it away for the summer (it is stored indoors) I drain out all the ethanol gas (you can do that by removing the vacuum diaphragm from the tank, all the gas will come out) then draining the carb float bowl. Then I put it back together, and put in a gallon of TruFuel, a non ethanol fuel meant for storage and small engines. It has rust and corrosion inhibitors in it. I connect it to a battery tender, and start it up and warm it up once every 2 weeks. This keeps everything like new till riding season again. I also have a couple of vintage Vespas I do the same way. Again, NO carburetor problems. ON an EFI bike, if you leave ethanol gas in the tank very long, it will destroy the VERY expensive in tank fuel pump. You can also destroy this pump simply by running out of gas. The gas serves as both a lubricant for the pump, and also places a load on the pump to prevent it from turning to fast. This is an issue with pretty much all EFI fuel pumps, including cars. EFI is just another way to say EPA. All emissions crap should be removed, including the float bowl vent, gas tank vent, and charcoal canister. The tank and float bowl should be vented to the atmosphere.
Not many people agree with your comments on EFI. Carburetors work fine indefinitely with a bit of attention to fuel age and quality. But EFI responds automatically to changes in temperature, elevation, and fuel quality, rarely fails, and avoids 95% of the problems that carburetors have. However, the remaining 5% of problems that do arise are difficult or impossible for a DIY mechanic to fix. That is a pretty good trade - just scan through the postings on forums and Reddit and see how constantly people post problems that all trace back to dirty carbs. I agree with you that ethanol in fuel is an abomination and and embarrassment to our political process. But it is manageable with conscientious use of fuel stabilizer and minimization of any fuel over about 8 months old. I have ten carbureted small engines on various scooters, generators, snowblowers, inboards, outboards, and power washers, all used seasonally, and haven't had a problem with ethanol fuel, although I know many people who have who are less attentive to the age of their gasoline.
Not to bash the tech advantage of fuel injection, but it took you damn near a minute to test a battery with your video game thingi. I would have had that battery not only voltage tested but also load tested in a third of that time. Just saying.. digital ISN'T always better.

Great video, Helped me to clean the carb in 125 LX, the carburettor was clean, but there was some dirt in both jets.
Thanks 👍
My God i’m glad I watched this before buying this scooter!
Hello! Very detailed and helpful! Thanks! How and where can I see in detail what you press 51:13 - 51:16 I miss the seals inside, there are three channels, how many rings - seal are there?
What's the procedure to adjust the right float height? What's the inclination degree?
great video rob always helping scooters riders
My hat is off to you!!! I would love to be trained by you.
Thanks

good job thank you for informations
How do l know if my carburetor needs cleaned or rebuilt?
Really good video
Thanks!
Thanks for some great videos, Robot! I have a question: there's a ground wire attached to the chassis/frame on the left side. I just found out that mine is not connected to anything. Where does this go?
excelente video Mr. Robot😀🎥📼📹
@Vespa Motorsport: what kind of technique do you use when replacing the old fuel line? How do you get the new hoses firmly sit on the carburetor/fuel tap/fuel filter? Do you heat them up somehow or use somekind of special tool to temporarily enlarge the diameter a bit?
Carefully cut the old lines off with sharp razor blade.
Great video Robot. At what mileage would you replace the slide as preventive maintenance?
Excellent!

Dont trust the drive belt after this long standstill of the vespa they like to crack.
