What did you do with the wire that used to go to the solenoid?...Did you just leave it hanging...or did you cut it off?
Also what happens if you leave the PTO on and get up out of seat...does it continue to run or shut off then?
You can also check the solenoid by running a piece of wire from positive terminal to the point at which the wire you disconnected was formerly attached....and then touch the solenoid assembly to the chassis...or the negative pole on the battery..if it clicks and you see the end of the piston move it is ok...if no reaction, then it is shot
If you are going to continue to run it without the solenoid you should put a shut off valve in the fuel line and use it or you will flood the oil with gasoline
