hi all! I need someone who knows holleys. I have a 670cfm street avenger which... idles 100 times better than my carter and runs pretty good down the street. I just have this off idle lean spot when I push the throttle a little harder. Idles at about 13.5 to 14:1 afr and when i hit the throttle hard it goes to 16...17...18...20:1 afr.
I have 65 primary jets, orange pump cam, upped the squirter from 31 to 35 but that seemes to have done nothing. I also get an instant pump shot. I Lready have bent the pumparm a little so it fully runs on the cam, seems to be a common problem...When I slowly roll in the throttle i dont see an afr change on my meter and i can take off slow but without the leanspot. I need the car tomorrow and have to get rid of that flatspot!
