I noticed an issue while working on my bovee install. My flywheel lacks traditional timing markings on the rear. Instead, I see a " 1 3 4 c 6 7 9"

The 3 is visible when the points touch.

So, has anyone seen this before? Is the c the 25 mark?

I have never seen Bowvee's instructions or kit but I have installed many of these. The Onan flywheel marks vary depending on when they were made. Usually there is a 0 position mark and then a 20, 22, or 25 mark.

If you still can not find it, you might reconnect the points and start the Onan. Then point the timing light at the flywheel and see if you can find the mark that way.

I'm an idiot. I was reading the part number on the flywheel. I eventually
used a screwdriver to find TDC, and found the markings soon after.

It's installed and performing wonderfully.

That is all right. We have all been there. Some will just not admit it.
