Ok 73 2.0 built to a 2056. Currently running points. Checked dwell and set to specs. I was setting the timing and I have a timing light that you can set in the advance.
1st question: Can you use the advance setting on the timing light instead of the 27 at 3500 rpm? 2nd question: My dizzy has 2 vacuum ports. One is advance and one is retard. My throttel body only has one vacumm port for the dizzy. Do I need both hooked up? 3rd Question: Do I have the vacuum line on the correct (advance) side?  4th Question: when I check the timing (just for fun) with the vacuum hose hooked up as shown the timing is not anywhere close to 27 at any rpm. That seems odd. |

That is the vacuum retard that the hose is hooked up to and should be plugged into the lower port on the TB. If you have only one port on the TB then this correct. When you time the engine pull it off the TB and plug it and the port on the TB. Time the engine to 28 degrees BTDC @3500rpms as you are using only the mechanical advance of the dizzy to set the timing. Then plug the hose back in so the vacuum retard is working which only works at idle.
Now adjust the idle speed. |
