dies with throttle
 

the last few days ive had problems starting my scoot,it seems to have some hesitation when taking off.just tried to start it and it did but it died.i put in a new plug and it started but kept dieing when I gave it gas.it was in the shop and the guy removed all the emisions but was running strong.the only thing I can think is a dirty carb.new plug and the air filter is clean.ant ideas guys

its a 50cc 2t

it has a new fuel pump(petcock)I have it idling now but dies when I give it gas

okay heres whats going on .while idling I took off the gas line to carb and my idle went up so I gave it gas and she was fine.i kept the rpms up and it was fine.rode it a few minutes shut it off still fine.so my question is it sounds like my bowl is filling up and flooding it but what would cause this(float valve)?

Either that or your idle mixture is too rich. Try adjusting the a/f screw on the carb. And you can adjust the idle speed screw as well.

I leaned it down a little and it runs great but its smoking a good amount even for a two stroke.when you lean the mixture doesn't the idle go down?

Nope, leaner idle = faster idle to a point.
If your carb is the same design as the one on my Zuma, turning the A/F screw in is richer and out is leaner. Try 1.5 or 1.75 turns out and see how it runs.

ok that is weird in for lean but ill try it,thanks

In is richer, out is leaner. It's an air screw, so the further out it is, the more air gets by and therefore leaner. The more closed it is less air and more fuel so richer.

these carbs aren't sensitive like others ive worked on.mine was pluged with a brass cover and I took it off
