Len - if it runs right and passes all the other carb tuning tests I would
think the mixture is about right.

 

What you are describing might be consistent with temporary/momentary low
fuel. You might re-check your float level[s], and make sure you aren't
starving it for fuel at high fuel consumption speeds.

All the best,

Hi all

 

Just finished repairing and reinstalling the carburetors on my BJ7. I
thought I had everything adjusted properly. According to my Haynes Manuel
the engine speed should increase slightly when you lift the piston a very
small amount. Mine does that.  My dwell angle is where it needs to be and
the car starts and idles nicely. Also sounds beautiful when I punch the
accelerator linkages. The problem is that when I get it up to 60-70 mph I
get what sounds like backfiring into my carburetors. Also sounds like it
doesn't have a whole lot left in the tank, so to speak. Does that sound like
I am running too rich or too lean?
