Too Rich: SBC 670 Holley Street Avenger

[c10seth]

Hey, all.

I have a 360ci SBC with an Edelbrock top end kit #2022. Compression ratio is about 10:1. 93 octane fuel with Stabil left over from winter storage.

I have the timing set to 12* BTDC at idle and 36* of Mechanical timing ~2,500 RPM (Vacuum advance disconnected & plugged). I installed a fresh set of spark plugs gaped to about .040" and within about 20 min of idling the truck wouldn't idle any more because the plugs were fouled out. I was getting between 5" and 10" of Hg at idle and I know it should be higher than that. A knowledgeable buddy of mine suggested it could be the Power Valve (PV) or my floats are set too high. I think my floats are ok as the the fuel level is just below the threads, from what I can see. As anyone had any issues like this? Thank you.

Kindest Regards,
