I'M A NEW MEMBER AND HAVE A QUESTION FOR YOU ENGINE GUYS OUT THERE. I RECENTLY WENT OUT FISHING ON MY COUSINS BOAT WHICH IS POWERED BY TWO CHEVY SMALLBLOCKS. HE TOLD ME ONE ENGINE, AFTER IT GET WARMED UP STARTS TO POP THROUGH THE CARB. WE WENT OUT FISHING AND AFTER ABOUT 35 MINUTES RUNNING AT ABOUT 3000 RPM'S THE RIGHT ENGINE STARTED TO OCCASIONALLY "POP" THROUGH THE CARB. I INITIALLY THOUGHT IT MIGHT BE TIMING BUT THEN I THINK IT WOULD "POP" CONSISTENTLY, NOT ONLY WHEN IT WARMS UP. ANY FEEDBACK WOULD BE APPRECIATED.
