383 Wont Idle with new to me 800cfm DP. Idles and runs ok with Edelbrock/AFB

I'll start out by name-dropping Vic Edelbrock here LOL that way I'll get some credibility and then you can listen to the rest of the crap. I just pulled a crappy one barrel Rochester off of a 78 and the float was sunk. The thing wouldn't Idol for crap. put help me with tuning my carburetors and I know you don't want to go into this on a tight budget but $150 wideband O2 sensor can tell you a lot about how things are burning. I'm the last one to cyber spend money but this is a great tuning tool for the unlearned...
Maybe. But you didn't need a WBO2 to tell you that the float was shot, did ya. :poke:
Please don't tell me you did!
:p
