What is the number on the PV?? I run 2.5 on everything, there isn't any need for enrichment above that number.....if you're vacuum is higher than that you're not at WOT, and that is the only time you need the PV...if the PV isn't working you will run lean, not rich, PV has to be working to run richer. Check your timing, put in lower PV's, then start lowering your jets sizes until your idle screws start to work...
