I've had a running problem with my 122 that I think I finally found the cause of yesterday: while mowing a yard that gets pretty grown over (the owner only wants it mowed every two weeks and it is irrigated), my 122 will gradually lose power and die. If I let it sit for a few minutes, it will start up, and usually repeat the problem until I add gas to the tank (I don't keep it full so the gas doesn't sit too long & go off).

Yesterday, I didn't have a gas can, and for some reason, after it quit once, it decided to run without a problem until I got that yard mowed. When I got done, I noticed the gas was boiling in the inline filter (non-stock fuel plumbing) and in the tank. Like pasta boiling-- vigorous. This I think is the reason for the running problems.

How do I keep the fuel cool given it is sitting right above the engine?

I realize today's gas isn't that great, but we're stuck with it which tells me that fuel tank couldn't be in a worse location, and I might be stuck with mowing in fits & starts.

Any ideas appreciated.
