new timing light new question
I decided to check my 70 gto timing with a new light that has the advance dial. I run points. Well I first moved my vac advance to the manifold, and capped the carb. Checked dwell at 30 degrees. Adjusted idle to 1050 idle and about 900 in gear. I run a Ramair 4 cam so it needs a little more to idle right . By turning the timing light knob when the line hits 0 on the balancer I am at 30 degrees per the knob on the timing light. Is this about right?
I went to check it by disconnecting and plugging the vac advance but it ran real rough back fired and by the time I turned it off I fouled number 1 plug. In fact the timing light would not work with the back fireing. I pulled the plug cleaned it , checked wires and decided to call it a day. Needed to get to T ball game.
I see the tuning sticky in this thread, I followed that and one on another GTO site, I did vac check the advance it does work, and I pulled the cap and rotor to visually check it out. It is missing the bushing under neath mentioned in the sticky and runs 2 silver springs. So I just want to know how close am i with the timing at 30 degrees with vac hooked up?
