Straight 6 timing
Hi all, long time lurker on this site and now I need some wisdom.
I got a 77 300-6. Its been on propane for the last 20 years and I have just switched it back to gas. Fired up and ran great from the start but it keeps detonating.
I found TDC and everything lined up with the #1 cylinder, rotor and teeth on the passenger side. Using my timing light i set it at 8 BTC and it ran good but still detonating. I have from there ran up and down from 14 to 0 and it wont stop detonating.
I have a buddy thats a 300-6 wiz and one hell of a mechanic and we played with it for awhile and he couldnt get it to stop either.
With it being on propane for the last while I didnt think there would be alot of carbon build up. I was wondering if someone might have jumped a cog on the distributor when timing it on propane or something.
I can only find 2 marks on the pulley and there both triangular notches. Should there be a line on there to?
Am I maybe doing something wrong or missing something?
Any input is greatly appreciated.
