Hi All,

I am trying to adjust my ignition timing on my 1955 235in engine using a timing light. My timing light has an adjustable knob on it. I know that not all the timing lights come with the adjustable knob.
This is what I think I know, TDC on my fly wheel is the triangle mark but the bebee is the 5 degree advance at idle. The timing is done using the bebee.
So, here are some questions.
1. If my gun is set to zero, I should set the timing so that the bebee is aligned with the pointer. Correct.

2. If I adjust my timing light knob to be at 5 degree, should I adjust the distributor so that the triangle is aligned with the pointer?

I am a bit confused with how to use the adjustment knob. When I have the timing light set to zero and I have the bebee aligned with the pointer, turning the adjustment knob seems to retard the strobe so the bebee is being retarded. I think that it actually should be moving the bebee in the advance directions?
Can someone explain to me how I should time my engine using a timing light with the adjustment knob.

Thanks,
skipper
