I have a old Bobcat 36" wb. I installed an '82 Briggs 18hp vertical twin. Since the bobcat originally had a Kohler 12.5 with recoil, there was no provision for a starting circuit. I wired in a starting circuit, using a Ford solenoid. It's your basic starting circuit, with a toggle switch letting juice flow from the battery through the toggle to a push button switch to the solenoid. Everything works fine. It starts right up. The problem is I can't shut it off. I choke it to kill it. By switching the toggle to the off position it cuts juice to the starting circuit. But of course that doesn't affect the ignition circuit. There is only one wire coming from the Briggs, I have that wire pulling juice from the solenoid for the ignition. Anybody have experience with these old Briggs? Another wire somewhere that I can't find? I'm going to have to pull the flywheel so I can get a look. Already have the covers off and don't see any more wires. Started this project a long time ago. But got sidetracked. Just started on it again. Went through the carb last night, bypassed the govenor and the old Briggs sings! Just got to be careful not to overrev it.
