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!

Merely speculating, that's deeper inside the engine than I went.

But I'd expect the tappet to sit on the camshaft, and to have the little recess on it. When you look down inside the engine, does what you see look like the included tappet that came with the pushrod?

Does the other pushrod move when you slowly turn the engine? If not, perhaps something went wrong with the camshaft?

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.
