I looked over those threads you posted. A bunch of useless info, but I did find something about the wire feeding the coil. Had to make sure I used a big enough wire. I have a 20 amp relay feeding it so no bottle neck there.
I hooked the tach back up, and at about 3000 RPM it finally hits almost 1K on the tach.
From what I have read. The resistors are only if your needle bounces around. Mines rock steady, just way way way to low.
And GOTHALOSISM, you never stated what your problem was.
