I have a 5 HP Tecumseh Snow King engine on my snow blower.
The fuel line that comes down from the gas tank goes to a Tee fitting,
and the line that goes to the carburator has both a fuel filter and a
shut off valve on it. The other line is about 3 feet long and is
attached to the handle with velcro strips. At the end of that 3 foot
long line there's a hose to 1/8" NPT male thread fitting and a 1/8 inch
brass threaded cap.
Whenever I'm finished blowing snow, I move the snow blower to the front
steps of my building, close the fuel shut off valve to the carburator,
and just let the engine run until is runs out of gas.
Then, when I get the snow blower into my boiler room, I use the long
fuel line to drain the remaining gas in the fuel tank into a plastic
Wedco gas can.
I'm thinking that running the engine out of gas every time I store it
for a week to a few months until I next need it keeps the carburator
clean. And, I'm thinking that draining the remaining gas in the gas
tank after each use of the snow blower allows me to put fresh gas in it
each time I blow snow.
Is there anything I'm doing that may be harmful to the engine,
carburator or the starting ability of my snowblower? Is there anything
you'd recommend I change to ensure the carburator continues to work well
and that the engine continues to be easy to start?
