tbone: what pilot and jet would you suggest for better performance on a 125 4 stroke
Hunter Bucklin: I got a 50cc scooter i just got out of the shop. it ran perfect before they messed with the carb, now it only goes 5 or 10 mph and struggles. when i remove the air filter it runs like it should, is this a jet problem?
Jay Aardahl: I have a 49 cc Chinese moped it starts and runs but soon as I go to drive it it cuts out?
ricardo Gomez: I need help I got the gy6 carburetor I get gas to the carburetor butt it won't start well it starts for a second or two and then it wont start I check the spark plug and its dry when I use a different carburetor from one of my other bikes the bike runs right what can it be I have also cleaned out the carburetor I adjust the fuel adjustment screw and there's no change no difference any help will be appreciated
Christopher Spohr: My main jet came apart into 2 pieces? all main jets I've seen are 1 piece???
twistdshade: Thanks man. I was stuck on how to re-jet the sucker and you have the exact same carb as me. You forgot to mention that the main jet actually comes out of the bigger brass in the middle. I thought it was one piece.
It shows it at the end, but maybe add some annotations to be more descriptive :)
Kevin Stearns: one important adj u left out the floats.
Kurt Bennett: Hi there. I have a gx150 spiderbox and just bought a new carb from buggy depot. Apparently there are chinese ones, but this is 'supposed' to be the more expensive one. Paid 100 or so bucks. Anyway, put it on and there is a lot of backfiring. I did not adjust anything. Just put it on. Is there a way to richen it up without swapping jets? I'd imagine this is a carb that is supposed to be able to be put on without an adjustment, but I've got way too much backfiring and its getting worse.
NZHorizones: What was this carb on, a 500cc 100cc 150cc?
Jim Rogers: i have a scooter that will run only about a min or so at a time, i bought a new carb with the same prob, i know it gets gas to the carb, the electric chock gets HOT to the touch really dont know if the chock works or not or if it could be the prob...HELP PLEASE
Tony Toni: I swear I just want to kiss you, you deserve to have donations made to you.
Rosemary Onyegbule: What brand and cc scooter is in this video?
Wooshvooshboosh: I have a 49cc Zhongneng scooter that was given to me by a friend, it runs at a max speed of 30-35, He told me I could replace or modify the carburetor to bring it up to a ~55 mph max speed. I cannot find the model of the scooter, so I believe its a knock-off, but it has the exact same carburetor as the scooter in this video. It actually looks quite similar in terms of air filter and engine to yours as well. What do you suggest I replace the carburetor jets or entire carburetor with?
Lost N Musik: Very Helpful Video. I am just getting me feet wet on a new Roketa 250 54B liquid cooled that wouldn't start right out of the crate. Battery was charged, fluids checked and fuel added to the tank. There was zero Vacuum to the fuel pump. After watching this and 1 other video about the source of the needed vacuum to run the pump, (intake manifold port) I suspect to find the vac. hose to runs everything vacuum related probably was never connected to the port on the intake manifold. Great job with the video by the way and thanks for the valuable information. With any luck, the loose dogs will be chasing me down a country road before long.....
abel berenguer: Tks four you great video, I have a scooter two stroke 50cc sym fiddle from 1999 the moment the petrol not came out from the tank to carburettor I by a new fuel vacuum pump because I thing is the problem, anyway I fit the new vacuum pump and still not came petrol out what you recommend to check first tank you best regards: Vinnie Berenguer
John Lefkowski: I have a gmi-106 i don't know what the name for it is, i just got it off a website for scooter parts. but i have replaced the starter relay and the ignition coil. and whenever i try to start it, it just clicks. whenever i press the starter it clicks. what would recommend to try and fix it
Nate L: How many kM has it been since the valve ADJ? I would check that again. On the taotaos It is very common to get a air leak in between the "air box" and the carburetor. I always assemble the cab and air box together before I put them on the bike so I know that it has a good seal. I would start with that and let me know if it does not fix it. GL
Dana Weston: i ride a 50cc taotao with a bigbore kit on it to 80cc. i know its something between the piston valves and the carburetor. im just a slow learner with this stuff
Dana Weston: over time they need to be maintained, understood... as the system "loosens" up over time. what things exactly need to be done. I get the piston valves must be adjusted using the feeler gauge, but do i just screw the jets in the carb to a certain point to "adjust" the carburetor, or is it a complete replacement of the jets. i do realize i could need bigger jets to allow more fuel through the system, but what makes this seizure in the rate of the idle, what exactly do i do to fix this?
