Default Missing Stover Timing Mark

The timing mark on my Stover CT 2, Hit-Miss, S/N 233953 is missing. Using the key way, I have marked TDC on the outer rim of the flywheel and need to measure back from that to make a new mark. If it is about 40 Degrees that is about 6 inches. Could someone who has a good original timing mark please measure the distance in inches between the timing mark and TDC. The circumference of my flywheel is 53.7 inches. Dividing 360 degrees by 53.7 inches is 6.7 degrees per inch.

I think your getting a little to technical, If these engines are out a little they will still run. It's good having them as close to dead on as you can, but as I said if your a little off it should still run. I've attached a couple charts I got from David Lyons, he had them posted and I printed them to help a newbie.I hope they help, just remember to time your exhaust first.

I dont have my Stover anymore but I do remember that when using the timing marks, it would fire a good distance before top dead center, right around 10 degrees or slightly more before top dead center. After I put a lighter spring in the governor so it would run slower, I changed it so it was firing right at 5 degress before TDC and it was running really well. It would fire and run up to about 400 rpm and then slow down to about 300 rpm before firing again. The original governor spring was really stiff and the engine ran really fast. I didnt like running it until I got it slowed down then I loved it.

It kept my driveway nice and lubricated
