still smoking
i just did a complete valve job on my 1990 yj 4.2 and it still smokes. i also have a slight back fire. its not noticeable unless you were to get close to the muffler. is it because he carb needs to be adjusted? the compression test show a reading of 135 psi to 155 psi.

Why am I here?

Depends.
Is it blue smoke or black smoke? |
