CAM TIMING

Did this engine ever run with present cam, chain, sprocket set up or is this "new?"

Or does it have enough miles (over 80K) that the chain / sprockets might be worn?

Re--read what I posted earlier. I told you "up there" LOL how to check or at least get some idea of cam timing

Hmm got me thinking.
Somebody had the same start up issue on here about 6 - months ago, turned out that the new camshaft was actually ground on a marine blank which fire backwards compared to automotive.
Highly unlikley but something to check.
