Re: [T3] Carbs popping


<x-flowed>DougG=> popping thru the carbs under acceleration.
=> ... anyone have suggestions? I'm suspecting an intake leak?

Actual backfire -- fire up through a carb -- is when an intake valve is open as the cylinder is firing. You may be right about the intake leak, but not, I suspect, the sort of leak you imagine. This is a timing or valve-train problem. Very not good, it can cause carb damage and possibly engine fire.

OTOH: To clarify, are you testing and seeing this while standing over the motor, or while driving? if the latter, it's more likely postignition -- fire in the exhaust system -- which is often related to an exhaust leak.
