I assumed that the timing is way retarded, but I will be hooking up a "timing light" to actually see how far off it really is.
Once I had find where the timing is right now, then I will start making my adjustments.
My reason for the original question was that I wanted to have a target to aim for.
I checked the compression and came up with #1--60psi #2--55psi #3--55psi #4--53psi (these figure were when the engine was cold--I know that it is normally done with the engine at operating temp but I had the spark plugs out to check them and I didn't want to put them back in (hindsight is always better than foresight) I will be checking the compression again at normal temp later).
I noticed that the spark plugs were very sooty, like it has been run too rich, however that could also be caused by incorrect timing? I will be installing new plugs.

I have never seen a timing pin as shown in the first picture in post #12 slide in that deep. Even when it has seated in the dimple, there is usually an 1/8th inch or more of the shaft showing. This one is right down to the base. Is it a stock timing pin? I don't have the measurement handy, but my best guess is that the length of the pin is about 1 1/4 inches from the base to the tip. If your pin is too short and it's bottoming our on the timing cover, it can't drop into the dimple on the timing gear.
