Re: Is My Timing Really 55 Degrees Advanced?
Okie Dokie, I used a piston stop and verified TDC. It was actually only off from the original timing mark on the dampner by approx 3/8". I then looked at the rotor, and it looked like it was one tooth off from pointing at cylinder #1, so I pulled the distributor, turned the oil pump back a little, and re-stabbed the distributor to where it was closer to pointing to #1. Put it back together and fired it up. Seemed to run better after turning the cap a little. Then, back to the timing light. I set it to "0", then turned the dial until I hit 12 degrees. Now the timing is at 35 degrees advanced.
Please see if I am thinking about this right; Doesn't the firing of number 1 cylinder have to occur in relation to the cam? I mean, I'm moving the rotor, but I'm not moving the cam, and the cam is what is opening/closing the valves. This car with the old timing was running really rich. I moved the distributor one tooth (27.69 degrees) which is approx. what the dial moved when I re-checked it. It seems to me, if I move it one more tooth, then if I'm guessing right, will bring the dial down to 12 degrees, which will also synchronize the cam (valve opening/closing) closer to where it needs to be.
I apologize that I have not yet done the Degreeing of the cam yet, as I did print off a degree wheel. I know that you are going to say: "If you had done that, it would show you what your talking about", but if this sounds correct, and all I have to do is rotate the distributor back one more tooth, I would be excited to try it.
The fact that dropping one tooth back changed my amount of advance from 55 to 35 makes me wonder if I'm still off one tooth. I guess that is the main question I have.
And P.S; I just want to say Larger Dave, you are a wealth of knowledge. I am really focused whenever reading your replies wherever I run across them. Every time you speak....I listen (just takes me a little more time to do what you say! lol) Thanks for your input Big Dave.
