You CAN'T adjust the outboards until you have a load on them...meaning until you DRIVE it.
A few things, I found that setting the floats a hair low is better than on the money, You can adjust your idle w/o the outboards hooked up...once you hook them up make sure they open 100% if not adjust the rods, I'd start by turning the screws all the way in and them back out 1.25...
You have much less cam than I do and I didn't have to drill squat. Start it up tunr the idle up to 2200 and let it warm up. set your timing to 36-38* full (vac adv unhooked) turn it back down to 900rpm, set for best idle vaccuum.
Go for a drive, now you can figure your PV/spring settings. What does the vaccuum drop to in gear? That will help w/ your PV selection...how fast do your outboards open? Now you have an idea about springs. I'm running the purples w/ 4.5PV and 35 Squirter.
