Carb super rich out of the box?
Hello all,
I recently purchased a holley 770 street avenger for my 393 stroker build and it is super rich. I have an innovative lc2 meter that is like 0.1 accurate and it is telling me at cruise im averaging 11.9-12.3 and at wot under 10.9.... I changed the front jet size to a 70 from the factory 72 and now my cruise is around 13.0-13.5 so it helped but I need to still go about 2 more sizes to bring it to 14's. Is this normal for a carb to be this rich from the factory? My WOT is still dipping down to the high 10's low 11's with the new front jet so I will probably have to also change that jet 2 sizes to help it out. Has anyone else delt with a carb being super rich?
