Pulling V.A at idle

Dig that, maybe I'm over thinking it.... it looks like the body screws in the plug opening, then you screw the middle in and out? I just can't envision how that would work, unless I knew the stop was in just far enough, or the piston was already up to the top. I've Lightly probed w/ a screwdriver before, while a helper moved the snout bolt. Man, I apologize for being a pain, and Highly Appreciate all Yer Help over the last 2 years. I'll look into making one, and doing some research. Or buy one in a while. Thanks Rob! I'm gonna get that gasket too. I was thinking, between the One Guy's wacked Distributor, and the fact that it was Dieseln' on shut off, it was too far advanced. But maybe that was the carburetor heat sinking? I dunno.

The middle "plug" of the piston stop needs to be stiff to turn, like a self locking nut, so that it will stay in place when you turn it in. It does not matter how far, as long as it's far enough to contact the piston. Turn the engine by hand clockwise until the piston contacts the stop, mark a mark on the balancer aligned with zero on the timing tab. Then turn the engine by hand counter clockwise until it makes contact again and mark the balancer at zero again. Halfway between those two marks is TDC. It "helps" to have a degree wheel on the balancer and a pointer, but you can do it without that.
