my b20 starts and runs great it used to shut off with the key but now you can turn the key off and the tractor keeps right on running. I shut it off with the fuel shut off knob anybody know what the problem is?
I actually worked on one of these today that does the same thing. I assumed that was just how it operated, some of the tractors only have a manual stop. I'll have to check it out when it is back together.
