I just had the intake manifold gasket replaced and now it’s backfiring out of the carb. It’s making a “popping” noise that increases with the throttle and slows when idling down. Did something happen when the mechanic changed the gasket? The noise was not there before the gasket change and is there the first time starting it after the repair.
