Montauk's Johnson Outboard Dieseling

I have a 1979 Montauk with a 1972 Johnson 65HP outboard. Bought it used this summer. Engine was well maintained and runs like a champ. The problem I have is that the engine does not shut off with the switch after it has been running a while and has to ber 'choked' to get it to stop. I think this is called dieseling. I vaguely recall the same problem my father had with a 1969 Johnson he had. Any thoughts out there?

Nope, its not dieseling. I had the exact same problem. Its the kill ckt. The motor is stopped by removing the path to ground to both power packs. The path is is provided to the powerpacks via the black wire with the yellow stripe in the key switch, with goes from there to the poere packs through the harness. The motor keeps running because the ckt has another path to ground.
Let me know if you need help,

Sounds good Larry. I peeked behind the console and noted that several of the wires have been pulled off the key switch. Where can I find out which wire goes where? I am pretty sure this is the original wiring harness but when I looked under the engine cover it was not clear which wire does what. I've got the choke switch as well to deal with. Thanks.

You need to buy one of the Clymer manuals for Johnson motors. A good comprehensive book store might have one, ore order online.
