This has been a mystery for me. Engine starts and run mint, however once it has warmed up and is idling for any longer than 10 mins, it then stalls out and I can't start again for another 30 minutes or so, engine just turns over. This occurred when I was pulling a skier, engine started to pop and as I gave it gas it stalled out. I've run several tanks of fuel through it and as long as it's not idling it will run all day long w/out any issues. Other than rebuilding the carb, I can't image what the issue is. Really a day killer. Any ideas out there? thanks.
