<div>The car has sat dormant for many years. It has not been driven for many years & is in rough condition. It has had the engine rebuilt, but I do not have any info about what was done. </div>

<div>Gary, I'd echo what Harold asked: What was changed before the car started acting up? Or, did it appear to start backfiring spontaneously?</div>
<div> </div>
<div>Often the issue is "maintenance induced".</div>

<div>At what throttle position does the backfiring occur? One possible cause is the timing is too far advanced. Are you able to check the timing at the point of backfire? Has any work to the valve train been done prior to the backfiring? I would suggest resetting all of the valve clearances.

<div>A club member's BJ8 is backfiring thru the carbs, HD8's. We have adjusted the timing & enrichened the carbs. I plan to revisit both of those settings. What else might be causing this?</div>
<div>Thanks,</div>
