B-112 Weird

Recommended Posts

Unless it has been converted to battery ignition with a coil like on a kohler, you don't even need a battery to make your tractor run. You should be able to start it with a rope, sans battery and S-G. Brent

I have been having a problem, with my B-112. After roughly an hour of mowing, it dies. The first time it happened, I made sure the spark plug lead was tight and it started right back up. The last time, I couldn't get it started until an hour or so later. Anyone have a similar problem? Next time it happens, I'll try to do a little more troubleshooting.

My guess would be the mag/coil is going out of it. I would put a magnatron ignition on it (if it doesn't already have one). It deletes the use of points. You do however have to send you flywheel to Briggs to get the flywheel repolorized (get the address from your local briggs dealer). They do this at no cost and you will have your flywheel back in about a week. You pay the shipping to get it there and they pay the shipping back. I would not put a kohler external coil on it. The point rod and cam seem to wear out on these engines not allowing to let the points to open and close. It will be cheaper in the long run to put the megnatron on it now. Good luck and I hope this helps. Ryan

When the engine won't start, do you have spark? If not, you probably have some sort of ignition problem (check the points and replace the condenser first). If you do have spark, it could be a fuel problem (maybe vapor lock). Is your engine overheating after an hour of running? Are the engine fins clean? Is a valve hanging up? Check compression when it won't start.
