I need some help in trouble shooting a back fire issue. My cj3b willys runs great at idle and low rpm while it was in the garage. Took her for the first road test. As soon as I give her more gas to increase power (slight incline) it starts back firing. Noise is so loud I'm concerned I will blow her new exhaust system. Any suggestions?
