Timing too advanced, overheating, or low octane will cause whats called "dieseling", which is when the engine keeps running when you shut off the key. Is that what's happening? Or like a boiling sound from the carb?

I would say it sounds similar to slow percolation. It will go on for a couple of minutes. This Bus seems to run perfect except the idle is probably too low but I haven't had a chance to bring it by my mechanic to confirm this. What could the noise be? Is it connected to the idle being
too low? Should I be concerned?At times when a Bus isn't running well then the possibility of "bad gas" is brought up. How often is "bad gas" the problem? And does "bad gad" just mean water in the gas? And does "bad gas" have a stronger negative effect on an air
cooled engine over a more modern water cooled engine? Thanks for thinking, Julie
