Alternative to battery ignition, 23D

[Chris727]

Hi. The Briggs 23D that came with my B-1 had a bad original coil. The PO was trying to put a new points type briggs magneto like the ones used on the 10 through 16hp cast irons, onto it. I don't want to use a battery ignition on this one because I may want to use it w/o a battery. I don't think it would work but does anyone know if you can use the newer mag directly in place of the old one? The flywheel magnets look different but the mounting holes are the same and physically it would fit? Thanks in advance. Chris

What about an electronic ignition module?????

Here is what I am working with. Original mag has a cut into the windings and plug wire is gone.

Here is the mount.

Here is the newer points type mag which fits fine, but will it work right? Doesn't magnet position affect timimg?

Roy,by "electronic ignition module" are you referring to the little add on kit briggs has to convert points to magnetron? I don't think that would work on the original mag. Thank You. Chris

Chris, I'm talking about the generic module that eliminates the points. Available from Stens, Jacks Small Engines, etc. Still requires the coil piece in your pictures.

I'd think iof the pick-up probes are the same distance apart it should work. Put it on and see if you have spark.

As long as the magnet is in the same place and the points close right as it passes by it should work, in theory. I thought I read somewhere certain 23d models did use the two leg coil like the later engines? If it works let me know, I've got a 23d to tinker with later in the year myself.

Well guys, Sorry but it didn't work. The mounting holes were off less than a 1/16th of an inch but it was just enough to prevent physically attaching the mag. Looked at a newer flywheel but it doesn't have the recess and mount for the older type timing key so a flwyheel swap is not an option either. Unless I had a good original mag, only way I see to go is battery ignition.

Try this guy. A friend of mine bought a coil for a 19D from him a couple of months ago. It should be the same. http://www.bser.com/ Also on a Google search, if the Briggs number that you need is 296834 I came up with these. http://www.google.com/search?hl=en&q=Briggs+armature+296834&btnG=Google+Search

ti had the same problem you are having but i did convert mine over to elctronic ignition usin the org flywheel i machined a coil bracket for it similar to the ones that i run on my racing go carts and pulling tracts

Ray, thank you for the link. Chris

No problem.
