no more safety switches to worry about and it ran for almost a half hour till it just shut off. when i tried to restart it and pulled the chock out it tried to run. i checked the gas and have plenty in the tank.
I'm getting in late on this and can't seem to find part 1 so...... Have you verified that there is a no spark condition when it quits? I had a 2 cyl Briggs once that would quit when hot. It turned out that the float didn't have enough drop and when it would get hot it would expand enough to shut the needle and not let any gas in. The statement about trying to run when you pulled the choke reminded me of it. When it quits, have you tried spraying something in it to see if it fires?
