Modifing outboard magneto to use an automobile point set

[green-thumbs]

Has anyone looked into the subject? I do not recall any mention on this site or elsewhere. It seems like it might be doable in some cases. Finding room and setting up location of points are issues that come to mind, There have been lots of coil and condenser/capcitor discussions. It seems worth looking into whether automotive point sets are an option in at least some applications,

I would imagine that in most cases it’s mainly a matter of determining the best position for a non-stock set of points to get installed into, then drilling/tapping the holes for retaining screws in the best location(s), if its necessary. Points don’t care where they’re installed, they’ll do what they’re designed to do in any installation. BUT –  If space is a concern, some of the smaller point sets used in chainsaws or snowmobile engines might be better options. Car/truck distributor points would probably require the most space and therefore mist not be the best choice, although the earlier magnetos like the Quick Action, Eisemann, and American Bosch magnetos used relatively large contact point assemblies. All depends on what you’re working on, I guess.

Here is an attempt to use some automotive points in a Atwater Kent timer. I suspect they found a disintegrating timer bushing, and not knowing how to resolve that issue, decided to adapt this set of automotive ignition points. If this motor would run, I didn’t try it, you wouldn’t be able to start the motor as intended, by bouncing it off of compression. It also would no longer run in reverse. It could only be started by spinning the motor in the forward rotation. It did have one of the factory rope pulleys but they are so small in dia. they are barely usable if the motor has close to new compression. The only thing salvageable from the original ignition was the timer case. Everything else was ruined.

 

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

While on the subject of A-K timer bushings ( which frequently are found to be bad) … here is the print for fabrication. Either aluminum or brass is OK

T2, Tubs & Joe. THANK YOU for your considered and helpful responses. I was not able to find specific information only advice to buy a solid stete conversion kit, It seeems to me that there is no reason it can not be done  if a suitable point set can be position on stator plate in the right position,. It would seem to boil down to drilling and taping holes in stator to located point set, . As they say
