I don't have the fix as ours has the EXACT symptoms (ours will some times pour gas out of the air hose/carb connection) but NEVER pull the choke,pull throttle back as far as you can and push the start button. It will "hit" and start then start feathering the throttle back and forth until it smooths out and idles normally. We have done this ever since we have owned it. This happens to ours when it sits for more than 4 days without running. Yes, we have done several carb re-builds and major tune-ups to no avail. Once it gets going, it is a strong,smooth runner!! Hopefully someone gives you a "mechanical" fix.

We purchased a true NOS carb from Roberts Farm equipment&Tractor parts. Starts like a dream now, should have done it years ago!! It did need to have the floats adjusted though.

Bad gas with a lot of moisture in it. Drain and clean the tank and refill with FRESH gas from the station (not the big barrel by the barn that can collect a lot of moisture).

Have you replaced the distributor cap? Might have a hairline crack in it somewhere. How old are the spark plug wires?
