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

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.

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.

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.
