I can't decide if I've set my timing properly or not. When I added a salvaged A/C system several years ago I replaced the pulley. The pulley has two marks on it, the one on the middle belt groove is wide and shallow and I assume is TDC while the one closest to the eng case and left of the other is a V notch which I assume to be the timing mark. The eng runs good timed to this mark (5 degrees ATDC), but it runs better when set at approx. 5 degrees BTDC. Several years ago it failed a state emissions test because of a bad cat and I had a guy adjust it to run it's cleanest and it seems he set the timing BTDC. My dilemma is do I set to recommended timing or where it runs best? Is it possible the pulley mark is wrong for my eng? Anyone have any thoughts about this? Thanks. Tom Smith 83.5 Westie |
