I guess some us just have harder heads than others. Some have more money than common sense and some of us just like the do things the hard way. haha

If you have a spark plug, it's even easier then drilling and tapping. Break out the plug insulator, find a dowel that's close in size - even a wood pencil will work. Run the piston up close to what you think is TDC (insurance so if you have an awww s@#t and lose your grip on it)put the dowell/pencil in and turn the engine via the crank bolt or whatever you use. A piece of masking tape marked/"gradulated" with a few lines will give you an idea of when TDC is reached.

Yes, that method does work and my big expenditure was a new $2 Wally World Autolite plug since I had tossed all my used ones. It sure ain't rocket science

Sometimes guys get in trouble because the damper doesn't match the timing tab. Here is a short page describing the differences in the three types most commonly seen and how to go about remarking the damper if need be. Cost is zero, but it won't trick anyone into believing you have a Fluidampr...

It's worth mentioning that using a cover still doesn't guarantee the timing marks are accurate- even if the parts all match. Manufacturing difference and tolerance creep can still make the marks off, so the best bet is to go ahead and do the drill to determine true TDC. DV gave a link earlier for determining TDC, here it is again.

The bolt holes in the cover can be carefully elongated in order to index it correctly if you find it's off.

I have a cover on my motor. I drilled and tapped the snout hub (no balancer on blower motors) for a couple of 4-40 flat head screws from the hobby shop. The screws are located so the cover only goes on one way. I can remove it and replace it without losing location.

I recently made one for my Gravely 1 cyl engine. It cost nothing but a little time and the rod is adjustable.
