hey guys, when i adjusted my timing a few weeks ago i advanced it a few, but now at about 4000+ rpms it doesnt sound right, like it is too lean or too rich, i dont know how to explain it...it feels like its bogging at high speed, not the power i expect. Im guessing i need to change the springs in the distributor?? How are those springs classified and which one will i need? Or how do i fix this?

Thanks
Aldo

If you put the timing back where it was does the problem go away?How much timing were you running and what kind of engine are we talking about.

This problem will go away if I put it back at 14*, it is now at 21*. This is on a cleveland, and with MSD 6AL ignition, distributor and coil. The problem though is that at 14* i get really weak low end response, and it feels great now, up until the 4000 mark.

With a timing light and revving the engine above 3000RPM, look at your damper mark with strob light.
