The Ford
Festiva stalling issue came back when the gas tank hit the 1/4
level point. Something the chainsaw repair guy said after he tuned up
our Stihl recently got me to thinking. His comment was that he had to
use his special carburetor bath 4 separate times to get all the gunk
cleaned out. This prompted me to give the Festiva another Seafoam
treatment, and it took over half the tank before the problem finally
went away, but it's running like it should now and it's all thanks to
Seafoam.
