I've spent a couple hours searching for an answer to my question. I hate to ask (because I'm sure it's already been answered), but I can't find the answer, so here goes.
#1. I'm attempting to set the timing on my '73 F engine. My flywheel has the metal ball, but no other timing marks. I understand that the timing needs to be set to 7 degrees BTDC, at 630rpm.
Here's my question.
Does the metal ball represent TDC, or does it represent 7 degrees BTDC?
I'm assuming that IF it represents TDC, I need to adjust my timing light to 7 degrees advanced, and then rotate the distributer until the flywheel ball lines up to the timing pointer.
Yes?
#2. The cylinder compression numbers are: 140, 150, 140, 150, 165, 127 .
Once I get the timing set, I'll move on to adjusting the valves. The exhaust is currently pretty black, and it definitely smells strong. The motor also feels like it extremely week. The spark plugs look black. They're not oily, but seem to have a lot of carbon buildup fouling? I originally thought it might be bad rings, but the compression numbers look pretty good. Do you think lifters/valves could cause these issues?
Thoughts?
Thank you for your help.
