You know, I've heard that ever since I started using mogas in my
planes, but I've never seen a cite, nor have I *ever* noticed a
problem with unleaded gasoline in *any* of my lawn mowers, leaf
blowers, or snow blowers.

I put 'em away in the spring/winter, and start 'em up the following
winter/summer -- and away we go. Same with my Honda Goldwing -- I top
it off, and it just sits till next year. No troubles.

My experience as well.

Last spring I got my chainsaw down from the garage
attic. It had been *at least* 10 years since I
had started it. Topped up the tank and it ran fine.

I used to run the gas out of the carb on my
lawnmower in the fall. Stopped doing it and
it didn't make any difference.
