For starters, we'll change out that fuel filter. We dont to take any chances on a break and a fire... good recommendation Bjorn.

We're running a new Holley 4150 600cfm. Up until a few days ago, the car was only started to drive in and out of the garage, so it really never got warmed up. It hasnt been until now were the engine gets fully warmed up that we started experiencing this problem. So I'm assuming it has to do with the heat and not a carb adjustment or worn carb parts. Should we try a wood carb spacer? Does that really help keep the carb cooler?
