[Healeys] backfiring

[Alan Seigrist]

Bill -

This usually suggests you have to do a complete tune up.  It can be caused
by a myriad of factors but the symptom is partially burned fuel which when
it hits the cold atmosphere gives a pop.  Do a complete tune up first and
then see if you still have the symptoms.
