Hi
Your doing a fine job once you install the new carb do a plug chop as its a good way to determine o if your jet size is correct and your air/ fuel mixture is right or its too llean or rich http://www.mopedarmy.com/wiki/Plug_chop Take care and ride safely my friend Yours Hank

Bad News:: i knew i shouldnt have tried and be mr. mechanic, so i install the new carb today and the fuel line yesterday then when i try and start my scoot today, ITS NOT STARTING ???? i noticed that the gas has reached the fuel filter but very little and the fuel hose that connects with the carb has no gas in it at all, could this be a vacuum issue, im so frustrated rite now, it has a brand new carb i tried starting it about 5 times plus one of the times i tried it the battery seemed slow, so now i have a battery issue?

Yeah the mixture screw can be a pain to get at. On my bike, I have to remove the side cover.
Your idle should be set around 1600-1800 rpms.

Usually tighter (clockwise) will lean out the mixture, but then I am not scooter expert. I, in fact, am reading all this to help learn what my son needs to do with the one he just bought yesterday.
