I'm almost embarrassed to ask this question...I used to know the
answer pat, but somehow over the years have forgotten it and for some
reason, I can figure it out...
My 79 B has begun deiseling for 5-10 seconds after I turn it off. To
make matters worse, it recently has stopped this deiseling when it
emits a LOUD backfire.
Here's the dumb question...what do I adjust to stop this? The timing
(advance, retard it?)...lean out the fuel mixture (turn the screw in
the middle of the Zenith diaphram clockwise or counter clockwise?)
Your suggestions appreciated.
