When I got my slant the distrib was one tooth off and the best timing you could get was about 14-20 degrees BTDC. This caused ignition knock and when I finally got round to setting the thing right (About 6 degrees BTDC on my '76?), I noticed another problem has seemed to be resolved. It used to be that on cold startup the engine would make a brief but loud and disturbing "knocka-knocka-knock" sound that would go away almost immediately. I assumed from all I have been told that I just had tired bearings (which I still probably do), but I haven't heard that sound since the timing was rolled back. Is it possible that the wrong timing was the cause of my startup knock? |

...oil pressure coming up slowly PLUS all that initial timing banged on the rod and main bearings with the high cylinder pressure. D/W |
