Alright....I stuck a vac gauge on the carb today....it was around 12 inches.....

So the stock power valve that comes with the Demon (6.5) is probably close.

I also changed the jets back down.....put 78's in the front and 88's in the back...Still got a pop or two.....so may contemplate going a little lower. It's definitely not as rich as it used to be....but I hate to get it on the lean side. Just may keep it the way it is now....until I can get it on a dyno.

Also seeing the fuel pressure hit around 7 - 7.5 psi....too high?
