OK so I have been doing some tinkering since this morning, I have adjusted the fuel pressure to 40 PSI with the vacuum line off and plugged. Fuel pressure at idle reads about 35 - 36 psi with vacuum line connected. Also, I am seeing roughly 10 - 12 inches of vacuum at idle which jumps as high as 20 inches when giving light revs. I also found that I was missing the screen under the PCV valve which was more than likely allowing oil to pass straight into the intake. So I put a screen in there. Once the car warms up it seems to idle much better however it is still not quite right in terms of running under light throttle. It stills sputters and runs sorta rough. Is it possible to check my A/F ratio without a meter? Is that a dumb question? lol

Also, about the balancer, i have read posts in other forums where guys said they ruined their Romacs (which is what I got) buy installing it misaligned and basically chowing the keyway on the balancer. This happens when you install it the "hard" way which is with a balancer installer (interference fit) and not the "easy" way which is to put the balancer in the oven for a short period of time which allows the balancer to expand at which point it simply slides onto the crankshaft snout taking all the guesswork out of aligning it. I guess i should have done that the first time.

Thanks for your input so far guys.
