  Is it possible to interchange a points style magnetron to one without points? The reason I ask is; I have an Allis Chalmers Big Ten with a points style Magnetron that is bad and I have a no-points style off a later B&S that I would like to put on? Is it possible or will it screw up the timing?

I think you are talking about the coils them selves? If so they won't interchange. I am going to go out to the shop to check something, as I have 1 magnetron 8hp and 1 points style. I'll see what the differences are.

Maybe I'm wrong? I just looked and the 2 flywheels look the same. If that were the case then It looks like all that you would have to do is swap the coils? Maybe someone else will know for sure. In the mean time I'll try to find out.

From what I see so far, The polarity of the magnets on the flywheels are reversed. So you would either have to swap flywheels or ship the flywheel to Briggs and they will reverse polarity for free, you just cover shipping. The other thing is you would have to put a plug in the hole where the points plunger is so it doesn't leak oil. unless you could just leave the points in and just leave the wires off??

 

It will be interesting if someone else chimes in that maybe has done this already.

I thought the coil and magnetron were the same thing?

Thanks for the fast input,Chris. I tried to do it once and it ran,but it ran terrible. I couldn't get any revs out of it and it would skip badly. I thought it was a different problem at the time though.

The one for the Magnetron (no points) is different, it has a built in transistor in it. it looks similar but it is not.

Do you have a flywheel that you could swap?

Ok, I see now. Thanks for clearing that up for a dummy. :wallbanging:

A couple things. I don't understand why he left the points plunger in the hole? It could pop out then you will be leaking oil everywhere!. And he didn't mention anything about the magnets on the two types being different polarity?

 

Like I said hopefully someone who has done this comes along and tells us for sure. If not I will have to do some experimenting on my engines soon.
