So i got my exhaust done today and hooked up my wideband. (Its a Auto Meter Sport Comp analog fwiw). i was rich everywhere like low 12's So I fiddled with the Idle screws and now im averaging low 14's, right at 14.1 14.2 average but it ranges from 13.9-14.4. That was as lean as i could get it. Idling at 800rpm (Its a M-20 fwiw) its a vortec 350 with a very mild cam, just a step over stock (Its gonna hit the trash can here decently soon, the cam that is). the Carb: Holley 1850-4 with a secondary metering block. And when i pull it here in a few imma slap on the quick fuel adjustable secondary assembly. Im going to pull it apart and clean it out right quick as well. If i remember right i have 68's and 76's in it now, so Im thinking dropping the primary down to 64's and see where that takes me, i have several of each set of jets so Im going to really sit on this thing. Does that sound like a good jet change to start with? I might grab Chuck and have him hold a camera as i run it through the gears.
