Dave have you been shutting off the fuel at the tank when it is stopped. I indicated the necessity of this in an earlier post. The needle and seat in the float bowl are not seating perfectly and allowing about 20 drops of fuel to leak past in an hour. This fills up the float bowl and starts leaking fuel into the venturi area. When you start it this fuel is sucked into the engine flooding it dramatically. You are getting spark, it is just submerged in liquid gasoline. As you crank it the fuel eventually blows out the stack, and it will begin to chug to life. Very hard on rings, and not good for oil dilution and other parts. The fix will be a combination of a new needle and seat, Or using fine auto body buffing compound and spending some time polishing the needle into the seat to clean it up (3 or 4 minutes of twisting it into the seat by hand should do the trick, AND!!!!!!!! shutting off the fuel when stopped for more than 10 minutes. This is the real issue with starting, not the idle issue Best of luck, JimN
