Apparently Your Engine is different than what I am familiar with. I have not seen camshaft timing marks on the cam sprocket and have no idea how to time it that way, so am no help to you there, sorry.

That is the main way to time the IP, with a dial gauge and extension rod and sleeve. Anything else is just guessing, and luck maybe.

The excess smoke at 3/4 is likely a combination of smoke screw turned in too far, LDA diaphragm adjustments maladjusted, over optimistically modified fuel enrichment pin, and as you indicated, mis-timed IP. But that's just my guesses, based on information given.
