MAINTENANCE
Draining carburetor
The carburetor should be “purged”
of alcohol at the end of every day of
running. Alcohol is very corrosive and
will cause a lot of problems if left in the
carb. The fuel line should be unhooked
at the carburetor and the bowl drain
screw opened to drain any fuel in the
system. Another option is to run the
engine on gasoline until it stalls. This
will flush any alcohol out of the system.
The carburetor should also be drained
at least at the end of the season when
running gasoline.
Filters
Always use an inline fuel filter to
prevent contamination inside the
carburetor. Air filters should fit the
carburetor properly and be kept clean.
Bowl gasket
When reinstalling the float bowl you
may find the gasket does not fit
properly. If the gasket is too small it
can be stretched to fit the groove. If
it is wet it may swell slightly and can
be set aside to dry and return to the
proper size. If you are doing a lot of
disassembly for tuning it may help to
have extra gaskets.
Cleaning/Inspection
Once a year the carburetor should
be disassembled for cleaning and
inspection. Look for wear on the jet
needle and inlet tip. Inspect and/or
replace o-rings and seals. If cleaning
is necessary a toothpick will work
for clearing any holes such as jets.
Remove the Inlet Needle and use a
Q-tip to clean the inside of the inlet
seat. Compressed air is also useful to
remove contamination. The pilot jet
has a very small metering orifice. If it
cannot be blown out it will likely need
to be replaced.
Always use a stop on the gas pedal.
This reduces wear on the carburetor
and the chance of a stuck throttle.
