Alright gents (and ladies where applicable) As much as I'm embarrassed to admit this, I have to learn and need to get this right. I've never properly used a timing light. Yep, not on gassers either. Tried once but that engine had other problems too so it was hopeless. A generous member on here loaned me his timing set up. Snap-On diesel pulse generator and adjustable advance timing light. Timing light set to 8 degrees of advance (can set to 9 but doesn't do halves). Problem #1 I've got everything hooked up correctly and cleaned the #1 line off, but the timing appears to be jumping a bit and the Tachometer on the timing light is anything but reliable. I'm going to go buy a new 9v battery for the pulse generator and try that, can't hurt. Problem #2 I don't know what I'm doing The engine is turning clockwise if you look at the balancer correct? Therefore if the mark is AFTER the timing pointer the timing is too advanced? And likewise if the balancer mark is BEFORE the pointer the timing is retarded right? Or do I have those backwards. Basically if the balancer timing mark is before the pointer do I need to turn the IP drivers (retard it more) or passenger (advance it more). Sorry I'm not normally this dumb but it's been a tiring day.
