AC Model C- NEED HELP!!

Thanks again, I'll let you know how I come out shortly. I disconnected the small wire on the side of the Mag and sure enough, I HAVE FIRE....!

Now it's on to the timing and carb stuff.....

Well, I did everything you said Huey, (I think) and I am getting fire at the plugs. I put the mag on the vise and turned the lug as you said. Great fire at the points. They are set at .020. I even cleaned them. Then I checked for the alignment marks on the two gears. Well, I think I got them right, the steel gear has a pall opening. Is this the right mark? It's the only one I can find. On the fiber gear, the only mark that looks like a "C" mark is in the center, and looks like a snap ring with the opening being the mark area. I lined that one straight down and the steel one straight up. Then you mentioned that I "Tip-turn the engine backwards" to get the steel gear tooth straight up. I don't know what you mean when you say "Tip-turn the engine backwards". I took the steel gear and turned it so it was up and turned the fiber gear down and then connected the unit together with the 4 screws.

Also I know that the firing order is 1-2-4-3. I think I am lining the wires correctly, they are in that order. As I am in the seat, facing the magneto cover, there is a hump on the cover that houses a brass rod inside the mag. I believe that the #l contact is to the left of that hump and #2 is to the right of the hump as I sit in the seat. Is that right?

Also, when the tractor wouldn't start after I put everything back together according to your note, I removed the complete mag unit, then turned the lug unit on the back of the mag 180 degrees and tried it again. Still no luck.

I wish I knew more about this mag, but I don't so I reach out to you who apparently do.

Thanks for any assistance.

P.S. The grass is probably good for another week now. Also, there is a big antique tractor show this coming weekend around here, so anyone who knows anything about these old tractors are working their own, so it is impossible to get them.

However, one time, I got a loud Backfire, only one, indicating to me that there is "fire" and "fuel", am I right? I don't think I have a fire problem. Probably just with the timing.

I am also going to look for a needle and seat for the carb. I think it is also probably over due.

In the beginning of your latest letter you indicated that as long as I had the gears (which ones?) lined up, I would need to go to the timing.
I think your procedure for timing will probably work if all else is operable.

The engine was rebuilt a year ago, so nothing is bad there. Were you referring to the timing gear and chain in the engine at the beginning of your letter?

Hope this makes my position better understandable.

Still working on it, Bob in NW Ohio.

I got the old 1947 AC "C" running again. Duey, those photos were all it finally took as there was no marking on the fiber gear at all. Your accompanying letter was the final point to getting it running. I am now going to have to install a carb kit, as the old one looks bad and is in nead of a rebuild kit. The "C": has a slightly sluggish run that it did not have before. Every thing in the mag is apparently lined up and it started right up. What would I have done without your help?

Thanks again!!
