Pulling V.A at idle

Just make sure the piston is down some and turn the engine by hand.
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.
