Could I possibly have to much fuel pressure im not running a regulator, but I only have a mechanical fuel pump. Another problem I have is if I step on it from a stop it dies when I let off. If I ease in it won't die. If I'm in park I can give it throttle no problem seems pretty snappy. Not sure...
If i get to the point where I feel like I may need to drill the holes, and I have an extra carb for parts whats size holes in which throttle plate would you suggest
I'm at 15 intial now and 36 total, but mixture screws still aren't working properly. The idle actually increase when screws are fully seated. Is 750 cfm too big for a 400 and should VA be hooked up to ported or manifold? It seems to run better on manifold.
Yes idle rpm increased up to 36 and with ran smoother and seemed like the throttle response was smoother. So how much is too much total timing. Seems like most post I see people are looking to achieve roughly 20 initial and and any thing over 38 total is to high. Is that not correct?
