Hello Jeff:
I posted a similar request a few weeks ago as I have been having the same
"problem". The car runs good but still cracks and pops on deceleration. I
suspected a burned valve but my compression tests are all in 150 area with no
changes from previous tests. I have noticed that pulling the choke out a
little seems to stop it which would indicate that it due to the engine running
a little lean, but the plugs look normal after a long run. I would be
interested in what you find if you fix it.
