[QUOTE="2strokesteve89, post: 168702, member: 1670"] So, when you had the carb off and the float bowl removed, what I do is try to blow thru fuel hose to carb with float hanging and there should be no flow, then I raise float by hand while blowing thru fuel hose until I notice flow, that doesn't tell me if float is correct height but it does tell me if the needle and seat is functioning correctly, if you did some test similar too this, then move on, if not then it needs to be rechecked.also, do you have carb cleaner spray? Or starter fluid?When cranking if you shoot some in air box and it fires (or tries to) that will tell you have a fuel problem also. Also if you have good compression and less than 10% leak down I wouldn't suspect valves. [/QUOTE]
