Cause of sm Solo 3hp not shutting off....

[BoxMN]

Starts great, runs great. But wen flipping the switch to OFF it just keeps running. I did buy and install a new switch, and same thing. So it is not the switch. 

I just choke it to get it to quit, but want to fix it properly. Any advice on what to look for beyond the switch? Thanks!

A wire from the switch to either ground or to the ignition module is disconnected or broke

Check your ground wire. (Black) Loose or broken. Ground out the spark plug to the head with a screwdriver while running.... bet that'll work.  That'll point out your loss of ground, too.

The de-compression button works for shutoff too.

My switch never moves from the "On" position, I just hit the decompress button to kill it.  If I remember right, I think SM actually recommended shutting it down this way.

DTro, That's the backup if the engine keeps running, but they recommend using the switch first.  Below is from their manual.

 

10. After using this machine, STOP the engine by allowing the engine to return to idle and moving the switch to

the OFF position. If engine fails to stop, press the decompression valve in to shut off the engine. If the ignition

switch has failed, DO NOT OPERATE until the ignition switch has been repaired by an qualified mechanic.

Apparently there was a know problem with the switch if they offer a work around in the user manual.

... or a safety feature...

That is what I remember also...maybe they put out a TB after the manual was written...
