Got everything back together, and it started right up, no smoke at all (before it smoked a little when cold). The only problem is there is a rattle/ticking noise from the middle part of the engine, possibly the IP. I am thinking it's out of time now. I've read a proceedure to check it, basically you're supposed to be able to get the crank at TDC, then remove a bolt from the IP, look inside and see a notch if it's correctly timed. My problem is I don't know where this bolt is. Does anyone have a pic of it?
