Oops, forgot to address the backfiring.
If it is backfiring when cutting the throttle at high speed or on a down hill then open the idle mixture screw 1/4 turn. Idle mixture screw is located on the bottom of the carb, just behind the intake manifold boot.
If it backfiring at high speed or under high load or while going up hill, check the float level.
If it is hard starting while cold and it backfires, then do a valve set.
If none of these helps the problem then check for air leaks in the exhaust system.
