After having distributor trouble, I was wondering how much work it would be to remove the dist. and install a mag. I have a spare mag and could have used it to track down the problem on the CA the other day. Might leave it on for good. Do I need a mag drive for a CA like the mag drive for the early WD's with mag? I assume it would be the same for the B,C and CA. And if anyone has one you would sell, let me know.
Thanks

| Later B's, C's, and CA's all used the same CE 125 Cubic Inch engine. I ASSUME that a mag would bolt right up and work just fine provided you go through timing it correctly etc. etc. since B's and C's use mag's on those engines just fine. |

My 51 has a distributor but I have been told they came out with a Mag. Unbolt the distributor and bolt a mag up.

| I don't know the history but I'll bet very few if any CA's came with mags. However the change is quick and simple if you have a mag drive that most likely you do not. You might find one off an early B that was converted to a Delco batt ign. |

So I guess the mag drive is somewhat of a hard item to find? Well I'll keep my eyes open. Thanks Leon B MO------------- Uncle always said "Fill the back of the shovel and the front will take care of itself". |

The distribuitor replaced the mag on the B, C, CA, WC, WD, and WD-45. Later models of all had distribuitors. In fact, we replaced many mags on the above units with distribuitors. If you have the proper mag for your tractor it is just a matter of taking off the dist and putting on a mag. Should work easily.
Howevr, since I still believe the dist is better than the mag I would look into a solid state dist and replace it with that.
Good Luck!

I have been back and forth with a distributor and a mag on a C I have with no problems. The C distributor is not exactly the same as the one that's on my CA.
I have been told the drive for some distributors is different than a mag drive. If they look the same they should interchange.

If it has an O.E. distributor, you will have to change the governor gear. A factory governor for a dist has the drive gear for the dist all as one piece. I know I have a mag governor gear somewhere, but I'd have to look for it. The only benefit I can see for having a mag would be not needing a battery and charging system. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

You said it better than I could. I have 2 such mag drive gears but won't part with them because I like mags as they are a self contained ign system. If your charging system isn't up to snuff you can still use the tractor. |

We have a few of the governers with the mag drive. But there may be a difference inthe housing too. If you can pull your distributor and see a round plate with 2 drive dogs ont he distributor, then you can swap easily. If you have a long shaft on the governer with a little gear on the end, you would need to change more than just the mag/dist.

As a matter of fact the first CAs were magneto equiped. As others have stated using the appropriate governor from another B/C/CA, and any mag from a B, C, CA, WC, RC, WF, or WD will work on your tractor. ------------- HANSEN'S OLD ORANGE IRON. Showing, Pulling, & Going!! |

Thanks for the info guys. I didn't think about the drive gear being different. Sounds like I will stay with the dist and put electric ignition in it this winter.
