Seems to me like your flooding the engine in some way.Make sure the carbs r tuned correctly,if the motor has points make sure they r gapped properly,check to see your fuel pump is operating correctly,that means primer bulb is pumping hard,vent cap on tank opened,put timing light if need on engine, check for rpm reading.Most of the time i write out a list for my self and try to eliminate all the problems within,otherwise purchase a original O.E.M manuel and you cant go wrong .................Cheers.....

When it won't start, check each spark plug wire for spark. Check the plugs: are they wet or dry when it won't start?

Symptoms also point to engine overheating.
