Back fires under a load on the engine

Post by Jim505 »

Today must be carb day!!

When I drive my AA and go up a hill I get a very sharp backfire just as I down shift. Timing is on, float seems to be ok. When driving on level ground it runs fine no backfires. Any body got any hints.

A leak in the exhaust system will cause backfires on deceleration
