Ignition Timing on K161S 7hp engine

[cub61]

Does anybody know how to set the timing on a K161S 7hp engine??? People tell me to remove the starter to see the timing hole behind the flywheel so that way I can shine the timing light at it. But my question is how can I set the timing on an engine if the starter has been removed. The reason I'm interested in checking the timing is due to the fact that the engine sounds a little advanced on the timing. If any of you guys have ever been to a tractor pull you have probably heard how the engine on a modified 2wd pulling truck sounds. It has that constant pattern of high to low rev at low idle. Well, that's what my K161S 7hp engine is doing at low idle. But it runs nice and smooth at high idle. Any help and suggestions will be greatly appreciated.

Static time the engine.

The flywheel is marked with a T (TDC) and S or SP indicates the spark or spark run point - 20 degrees before TDC. The points should just begin to open at the T mark. Point gap is .020. and can vary between .018 to .022.

The timing marks can be seen through the hole in the shroud.

I would just start setting the points at .020 and then .021, .022 till it sounds good. I have used .020 on all my 7 HP cubs and never have a problem. The pulley on the flywheel has notches so you can start them with a rope. I just looked at that picture and the starter is just unbolted at the bracket and rolled down. I just looked at my Original & 73 and it looks like they will roll down far enough to see the hole, so take out the top bolt and loosen the bottom bolts and hold tension on starter to start it and push starter n and knock off belt and roll it out of the way. You may have to take the wires off the starter but you can jump start it with the A terminal.
