What's a "carb bowl?"
Haven't heard that term for a long time. But then all my vehicles are FI.
Oh, wait, I think my wife's Metropolitan has a carb bowl. And my JD tractor... and my push mower... and my snow thrower. I guess I have more carb bowls than I thought.
I just run Sta-Bil throughout the system on everything that might sit for longer than a week and never have a problem. Everything starts right up first try, even after sitting for 6+ months.
I usually don't do that with my AK or 2 cars since those get used almost every week.
