Hi, just joined after reading the threads pertaining to my problem and I've checked the OVR, cold start valve, the dist. cap, rotor, plugs, wires, O2 sensor, pickup from flywheel, throttle switch and also bought new battery. This thing will start: I try it 1st time for 20 sec. will not try to fire. Wait 10 min try again this time pedal 1/2 way down after 3 sec. and it tries to fire. Wait 10 or 15 min and try again. This time with no pedal it starts to go and will if I give it a slight bit of pedal. Also, this thing gets terrible milage. I don't know where to go from here. Please help!
