Finally got the old girl running. Took a couple of weeks, but wrapping it up. Adjusted valves, new timing belts, new tires, and rebuild carb. Took me all day to sync the carbs cause of chasing vacuum leaks. Intake tubes need to be tight.... Carb sync seems to be even across the board @ 5lbs.. should I have more? Maybe just an old motor having 88k.
Fuel mixture has me puzzled though. with all 4 at 2 and a half turns out, there is no difference in rpm if changed to 1 and a half. Getting some backfire at rpm above 7000. Pulling out in first gear it seems to be sluggish. I have read ALL of the forums concerning this, but is not specific enough. Backfire indicates lean meaning I should turn screws in to richen mixture.. is this right?
