A club member's BJ8 is backfiring thru the carbs, HD8's. We have adjusted t=
he timing & enrichened the carbs. I plan to revisit both of those settings.=
 What else might be causing this?Thanks,Gary H.=C2=A0

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.

Is it backfiring or spitting? Backfire in a carburetor occurs when the =
air-fuel mixture ignites at the wrong time, often causing flames to =
shoot out of the carburetor. This can happen due to issues like a rich =
fuel mixture, incorrect timing, or vacuum leaks. Spitting is ejecting =
oil thru the carb. At least that is true for my HS4 carbs.

Gary, I'd echo what Harold asked:  What was changed before the car started
acting up? Or, did it appear to start backfiring spontaneously?

Often the issue is "maintenance induced".

Humm, lots of possibilities there (e.g. fuel gone bad, rodent damage to
wires, something amiss in the engine build, etc).

It sounds like it starts and runs, so that's good.

You might walk through the workshop steps for engine timing and carb setup,
just to ensure the basics are correct. It's tedious but likely to reveal
something.
