[Rhodes22-list] Gas Tanks, Vents, and Carburetors

[David Bradley]

Mark,

For my last boat I had a 3HP Yamaha.  Unless I was sure I was going to use
the boat again that day, I always closed the fuel valve and let the
carburetor empty.  The motor worked like a dream for 5 years.  Before that I
had a larger Yamaha outboard on a Boston Whaler.  I was not as diligent then
and the motor really had a hard time starting and running smoothly due to
gas sitting in the carb (turning to varnish, so they said).  In my new boat
it will be part of the shut down routine every time I'm putting the boat
away, even if I plan to use it the next day (those plans have changed too
many times).

Has anybody used a shut-off valve for an external fuel tank, or do you just
disconnect the line, let it run dry, and reconnect?
