Troy Bilt calls it a after fire solenoid..basically keeps it from backfiring if I am understand it correctly. I could see a ground wire hanging, we must have knocked it loose replacing the belt lol
Can't make the fix until my buddy helps flip it, but hopefully that's the last problem!
Thanks for the help!
it shuts off the fuel so it will not continue to run after it is shut
off with the phrottle open -after-run, or Deiseling. or afterfire -
basically running with no spark - which CAN also cause them to "run
backwards" when shut off, pouring smoke out the carb
