Lippy,

I think I disagree about the four window PV...here's why: at one point I made just one change: replaced the 2 window 7.5 PV with a 4 wind 7.5 PV - no other changes. Tried to start it but ran so rich that I could just barely just keep it running. Vacuum gauge showed why: as I was trying to warm up the car the vacuum kept dropping to just under 7.5"; all that extra flow through the high flow PV richened it up too much. I put the 2 window 7.5 back in; although it was still in warm up mode, it ran OK (well enough to warm it up so that it could just idle at 11.5").

G Edmonds,

I'm gonna try to add the 50 cc pump and bring the squirter down from 42 to 37-40...

Also, I also changed the HSAB and PVCR in the 2ndaries but didn't change the Primaries...gonna make those same changes in the Primaries also to help WOT.

Thanks.
