February 22, 201015 yr Author comment_310326 tested test coil today with breaker point dizzy, no change ugh!completed compression check. 1 145, 2 140, 3 145, 4 145, 5 145, 6 145. all looks acceptable.tested test dizzy from a 1978 280z with gm hei. results in. no erratic bounce in timing at idle (great) when checked with timing light. cars runs better (I had to take it for a spin). all spark plug wires are firing at idle (verified with timing light) accept cylinder one. getting late atm so I will have to save the rest for latter but it looks good so far. have to replace the cap and rotor as they are very very old. mechanical advance working correctly. have to work out the kinks over the next couple of days so I dont want to say this one is solved just yet but it looks promising atm.
