How to tune ThermoQuad secondaries?

MopeKid - Don't give up on it. Sorry the re-jetting didn't work out...but richer is better than leaner - and it'll end up closer to .140 than .125 by the time your done.

I guess I owe you a bridge! LOL!!

Do what Dave suggests, he's the guru and then you should get back to us.

Make sure to tell us what the cars doing exactly so we can tell if things have changed ....

I remember asking if you checked the secpndary valves - Did you check to see how far the secondaries are actually opening? Are the butterfly valves vertical, or slightly angled?

FWIW there's still some other things to check as well, but get back to us on Dave's suggestions.
