I've got a holley carb that's been freshly rebuilt just this last year. I've tuned it to the my car but it seems like every week I have to retune it just PERFECT or else my car runs like crap! I've heard that holley's were finicky but I didn't think it was that bad. Anything suggestions on how to keep it in tune longer???

I know this is kinda late, but the only way to fix your tuning problem is to junk the holley.

:iagree:
IMHO, holley carbs are not meant for daily drivers, been down that weekly tuning road before... A Q Jet may have 10x the parts of a holley...but once you get them set...they stay set.

If you want a good performance carb get an edlebrock. Lil bit expensive, but they dont change once you get em set
