Hi naj, George,
I recently had my distributor rebuilt. Prior to rebuild the shaft was very wobbly and the timing would jump back & forth by as much as 5 degrees. Now it's nice and tight, no timing jumps, and its clean and looks great!
BUT, I cant get the timing set per the book.
It does not "jump" around the 2200 range to 30 degrees BTDC. The only way for me to have it set to 30 degrees BTDC at 3000 RPMs is to have the lower end at ~10-15 degrees BTDC at 1000 RPMs in Park/Neutral(in gear the idle is ~800 RPMs). In this setup, the car is very responsive, but the high idle bothers me and when I shift from Park to a drive gear, I get a thud vs a smooth shift.
I have darn just about replaced eveything else, except the 2-way valve. It seems to test ok, but I have ordered a new one in order to fully eliminate this item as a possible culpit.
Thanks for your continued interest and comments, advice!
