I just built my first motorized bike with the new 2010 80cc engine and I am having some trouble. At first it was working fine, i was only pulling the throttle about half way and going about 15 mph but the second time i took it out to ride it started spitting and popping, then as i would twist the throttle it would lose power, not accelerate, and sometimes stall. Ive tried adjusting the choke and idle screw on the carb but i dont know anything about how this idle screw works so i doubt that it helped any. Does any one have any thoughts about what could be causing this problem? The way my engine is sitting the carb is at about a 45 degree angle, could this contribute to the problem?
