I'm running a holley 3310 with the acc pump tweaked
and have it jetted and spring'd for my engine. Eddy
air gap RPM manifold, eddy performer RPM cam, head
work on stock heads, don't know compression ratio
exactly as I didn't build it, but compression
tests put me about 190 psi cyl pressure.

It's weird, it's like my no 2 cyl is "off" some.
It smooths out once I have my advance set up to
about 25-30 before (yikes)checked degree on camshaft
last year when I replaced the timing cover and that
was good. There's a noticeable difference between
the old disty and this (high performance) one.



Any chance you broke/bent the #2 plug wire? Wires laced correctly?

Check the rotor and make sure it's on correctly. Remove it and turn it upside down. Look underneath near each of the screw holes are. One side had a small male square, the other side a small male circle. Make sure they're oriented correctly on the dizzy. Check the PN on the module while you're at it and confirm it's correct

You're capping the vac pot while setting the initial, correct?

Going by your combo you probably ought to be near 15* initial w/ silver springs and the 20* limiters.
