I ussually shut mine off due to the vibrations and it ussually starts right back up, first pull. Although I wont say I didnt try. They vibrate so bad and the tank is on top, so when it gets near full, gas goes flying evrywhere. No need to worry about gas on a hot muffler. Gasoline will boil, it wount ignite from heat. I proved this to my son on a camping trip, by putting a container of gas in the fire and you could watch it boil from the fire, but never ignite. Probably something he shouldnt have mentioned to his mother when we got back. I will have to incorporate one of those "What Happens in the woods, stays in the woods".
