Quick Fuel Slayer Rich!!!! installed LC-1 wide band
I been tuning my car for sometime now. Its tough being new to an unfamiliar engine and components as we build these cars (novice). The deal is everything is somewhat new to me. New dist., cam, carb, exhaust, ect. It ran like a turd. I re-curved the dist. light springs and made a little more power with 19* initial, 16* in the dist. 35* total with V can plugged.
However, the quick fuel slayer 600cfm carb was running extremely rich. Had it adjusted 1 turn out from the seated position on the idle mixture screws. Was adjusting it to get the best vacuum reading of 17-19". Which I thought was pretty good with the very mild xe256 cam. I was still running way rich.
Well today I got my LC-1 WB installed. My AFR was in the 11's at idle...O-boy. Reset my idle mixture screws about 1/2 turn out from seated position and now my AFR is 13.9 (better). My guess is ill have to jet it down form the #68 mains to probably #66.
I still need to go for a ride tomorrow and see how the rest of the throttle relations are reading. I'm going to order those jets and a new 8.5 power valve. Does this sound about right to the experienced folks out there? Hopefully im headed in the right direction. Got my new fuel pump and regulator installed as well. It's set at about 6.25psi. I figured ill leave it there for now. Don't mind my wires bellow I will get that cleaned up.
