We all recommend a muffler on yours. It will not run better without a muffler, It will sound like it runs better to you, but not to the cops or your neighbors. You will get a headache on an extended trip.
Constant loud sound is how they get secrets from the enemy. So be careful not to give up your pin number.
To be clear, you can run without a muffler if you want to. There just is no known advantage to a 235 stock motor. IF the backfire is cause by low "backpressure", tuning the carb will not help. (not sure what "tuning" you would do to a B1). You may mess up a good running truck however. Adding a muffler may not stop the backfire either.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
