Thanks for the reply - I cranked the motor until a tap on the accelerator caused the squirters to squirt (my standard drill for refilling the bowls), and I did remember to connect the PCV hose.

I didn't check the carb-to-intake gasket. It's one that's been on the car for a while, and is a thin paper-feeling piece. I also didn't put a whole lot of muscle into bolting down the carb.

Is a carb backfire due to air leaks above the manifold?

Thanks,
