She works!! I adjusted the valve clearances and all of the intake valves were about .002" off. Next, on a hunch, I messed with the timing and I advanced it to about 20 BTDC and she purrs, fantastic acceleration, like she's a brand new car! I tried more retarded settings and 20 seems to be it. Why on earth would the timing need to be advanced so far? I checked the cam timimg mark while I was adjusting the valves and it was right-on at TDC for the #1 cylinder and not much play in the chain. Does someone have a good reason for such a difference from the 4 ATDC recommended setting?
I'm so glad it's finally over! Thanks to everyone for your input - I couldn't have stuck with it without your support. Now, what else can I work on.....
