my simplicity pro was running great last week, and now won't start. i cannot pull the starter rope unless i remove the spark plug. i took apart the carb bowl, removed the float and needle and sprayed with carb cleaner, re-assembled, no better. i squirted some gas in the cylinder, replaced the plug, no difference. it has electric start, i have popped the GFCI several times at the outlet. not sure what to do next!

ah, here's a new ominous clue. the exhaust valve is question, i can only depress about 1/2 inch and it hits deadstop. the other valve will go at least twice as far. turning the motor over doesn't seem to affect this.

penetrating oil and a whack from a small hammer and i'm back in business! however it won't continue to run over a minute. i'm sure i messed up the carb when i dissassembled that earlier.

there is no gasket between the bowl and the carb, i ripped that and didn't replace it. no leaks, tho.

Took the bowl off the carb, removed the float and needle, and for the first time I pulled the next piece out, a plastic disk like thing, blasted it good with carb cleaner, and I'm back in business. Just did 2 driveways, a foot of heavy snow, ran good. Thanks for the help! I'm a Happy boy.
