FBO Ignition upgrade

The rotational movement is part of the mechanical advance. As the RPM increases, the weights move outwards and turn the top portion of the distributor shaft/rotor to advance the timing. So what you are feeling is 100% normal.

If you have carbon in the cap, replace it. The carbon can cause all sorts of issues with misfires.

Ok ten four on the rotation I didnt know if that small amount of movement I was feeling was normal.

Movement or slack?

No..rotational movement...just a small amount clockwise or counter clockwise...i had a bunch of old distributors laying around and never noticed that they did that.

Use a vented cap and heavy duty rotor if you're not already.
