[QUOTE="RossKean, post: 1437656, member: 19880"] What a pain in the ass! I would be embarrassed to say how long that took. There are five wrong ways and one right way - I found all the wrong ways. Probably would take an hour the next time (if there is a next time). I found it very difficult to clearly see if it was in time via the marks on the sprockets. Even with an LED flashlight and an inspection mirror. I relied on the "oil hole" in the camshaft as a first approximation. I have a thin metal ruler I laid along the engine casing which helped. Found that even when I could see the timing marks, parallax made it difficult for me to decide if it was right or not. I think a fiber optic borescope would be helpful. Anyway, engine is back together and seems to run well. Started immediately, good cold idle, came down to around 1200 rpm when warm. Took throttle well but I didn't get a chance to take it for a ride. That will tell me if I did everything right (this time). Started with air screws 3/4 turns out and did a TBS. I was planning to do a throttle body cleaning but I'll leave that for another day. Enough drama with the valve check. I appreciate the suggestions and helpful pointers. Thanks [/QUOTE]
