So I took apart the carb and cleaned as best I could. Cleaned the main jet, high speed idle, and the low speed idle jets and still the engine won't run. I have tried spraying gas into the carb inlet and it seems to want to run, as in sputtering and can see the exhaust blowing out smoke and even pouring about a teaspoon of gas in the spark plug holes and it seems to want to start but will cut out immediately as soon as I let go of the ignition key and I am assuming when the little but of gas runs out. So according to the manual if the engine is cold, supposed to start it with choke pulled out and throttle in about half position which I am doing. What I did notice is that the throttle from full speed to the slowest speed, the throttle flap that moves inside the carb does not move very much. At full throttle the flap is completely flat which makes sense. But going from full to the slowest throttle speed, the flap barely moves at all, only about a 1/4 movement, the flap can still move a lot more before it's closed off. Is this normal? Should I adjust the throttle, or does this still sound like I need a Carb rebuild kit?
