Okay, my bad.  I'll take the hit - probably should have been clearer.  May need to get an administrator's help in moving this down to the Engine section.



This is where I was thinking first too.  Tune up status and what you have.  As we get deeper we'll know more and can help more.

Welcomed msk.
We know nothing about the service history of your engine.
There is a small multitude of conditions that effect your trouble.
Therefore you need to follow the factory tune up sequence.
If you have a proper service manual then follow the sequence as printed.
This should get you started.....

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?
