| | Lean tip in
I dont have an ls, but a carbed first gen 383 in my 96 z28. I hope im not bashed for posting in the wrong section, but my question should be universal as far as carbs go. I have a holley 650 dp on top of an airgap. Front jets are 67, rears are 73. Squirters are 31 front, 35 rear. I finally have the car running great. I recently installed a wideband o2 gauge. I am idling at 14.3 - 14.8. Cruising at about the same. My issue is on tip in to medium or wide open throttle, I get a lean spike that jumps in the 18s. It only lasts a second, then recovers. Is this normal, the air moving faster than the fuel is catching up? The car doesn't feel like it stmbles at all. If it wasnt for the wideband, I'd never know it was happening. But..... I DO know, so if i can fix it, i would like to. I tried increasing front squirter and i was fouling plugs within hours. Any suggestions would be greatly appreciated. Maybe Its a sacrifice to be running so good everywhere else? Thanks in advance.
