External coil??

[gtwygreg 0]

I was working the old 3416H this weekend and ran into some trouble. When I bought the tractor it had no spark, it's a 16 briggs cast iron engine. The previous owner gave me a new coil that would bypass that point system and I installed that. I put her back together and she ran great for a couple of minutes then killed. Then it would run off and on; I checked the spark ans it was weak or not there, so I figured it was a bad coil. I then got a new older styled coil, points and condenser and installed that. I set the gap at .020 and set the coil for the proper clearance as instructed. I even checked the timing with an ohm meter like the service manual said. The magnet met specs outlined in the help section of this site, so I figured I was good to go. I installed the motor and it was the same problem. I even disconnected the ignition lead to make sure it wasn't a bad ignition switch, still the same problem. I'm assuming the flywheel magnet is bad, but nobody in town knows how to re-magnetize one. I was thinking about just installing an external battery powered coil and saying the heck with it, I'm sick of taking this engine in and out. Has anyone else done this type of thing? I know the older Kohlers have an external coil, so I'm assuming I can do it. Would a car coil be too strong, or should I use one from a kohler? Anyone have any advice?

Do a search for coil conversions or battery start or briggs ingnition conversion.

I'm having the exact same problem on a exact same tractor. I pretty sure I'm going with an external coil. I should have done it in the first place. I my post "Briggs Magnatron ?" from yesterday. Lots of info on this just do a search.

Greg, Steve, I have been running a battery ignition with an external coil on a B/S 243431 engine for 20 years. Haven't even replaced the points or condenser since I put them on, back then. If you have any questions, PM me and I will try to help you. There are several ways to wire up this setup.

I just did this conversion on my 7016. See this thread: http://www.simpletractors.com/club2/topic.asp?TOPIC_ID=80667&SearchTerms=coil Like others, I did this to avoid having to remove the engine to replace the magneto coil on top of the flywheel, and I'm glad I did. Follow the instructions given by the folks who have done it. Wire the coil directly to a separate toggle switch on the dash and still use the key to start the tractor. It's easy, provides a hotter spark and best of all when the automotive style coil eventually wears out, its a 5 minute job to replace it!
