starts ok. after warm up blip throttle stays up 3000 rpm. had carbs apart and cleaned. if i put hand in front of either carb idle goes back to normal. sprayed carb cleaner around carbs,crank ,engine no change in rpm. thanks in advance
I think the idle fuel mixture is just a bit on the lean side. Turn in the pilot air screws 1/8 turn. Let it idle for a bit then try it again. Repeat procedure.
