Finally got around to looking at the ignition timing after changing the timing belt a couple weeks back. ('83 245)
12 BTD at idle, as it should be. Then the weirdness begins. Rev it up a little and timing retards to ~5 BTD. Rev a little more, say 3500, and it creeps up to 15-18. Rap it and it appears to go up from there. So, what's up with the retardedness? Can't be good for performance. btw, I have the vacuum line on the knock generator plugged so the motor doesn't ping all the time... and, so it will pass smog.- posted
