Posted this to misc.rural a few days ago, but got no real answer, so I
was hoping someone here might have an idea:
I've been using saws, cutters etc. for, oh, 30 years. By no means an
expert, but I have used them in all sorts of weather, terrain,
temperatures and elevations.
Yesterday, was using my Husky 232R brushcutter for a little more than
an hour and was on my second tank of 50-1 mix when I decided to take a
break. Swigged some water for about 10 minutes and walked back to the
cutter and noticed that the fuel tank cap was shimmering with
dampness. Looked closer and saw that the gas was "bubbling" out of the
gas cap vent hole.
Unscrewed the cap and it opened with a "whoosh" of escaping air.
Noticed that it kept doing this all afternoon. Now, of course it was
warm. But I've cut in much warmer weather and never noticed over the
And, gas fumes escaping would be logical, but liquid fuel bubbling up?
As I said, no expert, but never saw this before. Normal?
