Rasp933 Posted July 1, 2013 Report Share Posted July 1, 2013 Whats up .ratsun I have a buddy .that is running 2 weber 40dcoe carbs on his l20b.ok first he does not have fuel pressure regulator install ed in the fuel line.second when the cars sitting idling at the light .n when u start to accelerate the engine stumbles and when u let go throttle it back fires. And also when the car is sitting for a while its hard to start .and stumbles n backfires. What could b this symptoms relating to? Iam guessing the float is sticking. Any inputs in this situation fellas? Quote Link to comment
