Installed new Holley Carb
I finally replaced my 4777 DP with a new 82651 DP. Both are 650 CFMs but there seems to be a world of difference. The install was easy since both where 650 DPs. The initial settings from Holley seem good. I used a vaccum gauge to set the idle mixture.
I was planning to continue to run the 4777 and remove the choke tower but I think I made the better decision.
Any things to check besides gas leaks? I will pull the plugs later to check the main jetting / running mixture.
