Just got done playing with our BA6 aux. heater by trial and error.  Last
weekend tried it as per Bentley and it makes no sense at all to me.  The
heater started to smoke so I looked it up in the book�diagnosis, too much
fuel.  Test and find that the pump is putting out almost twice what is
called for�back off the adjustment till it is within specs and try it out.
In the driveway, no problem�on a trip into town, low heat output and then a
backfire sound out the tailpipe. Seems like too little fuel to me.  I live
almost at sea level so that doesn't seem to be a question as I've read
about in the archives.  Today I gave it some more fuel w/o testing (about
half of the earlier adjustment) and it seems better.  Anyone with any ideas
of what I should check next?

Thanks,
Mark Sheflo
