Mileage and vents

[jim schroeder <cretin@xxxxxxx>]

I've got 11,700 mi. on Sable now, and remember there was a problem with the vent
line under tank being kinked before the 600 mi checkup (when opening tank it sucked
air) Lift tank and ck. routing of all tubes! Gas mileage has never changed however,
always around 50 mpg whether loaded for a 3 week trip (full camping regallia) or
solo flight thru the twisties. Apparently you've got some other problem with that
minimal of mpg's.
                Good Luck,
                                Jim
