CARE AND MAINTENANCE
To ensure that you obtain long life and peak performance from your
engine, observe the following.
Avoid running the engine under dusty conditions.
If necessary, lay a sheet of plywood or hard-board in front
and under the nose of the model when starting the engine.
Foreign matter in the fuel can cause the carburetor jet to be
partially clogged.

Therefore:
rinse out the fuel tank with methanol or fuel before installing
it.
Install a fuel filter in the fuel line between tank and
carburettor.
Install a fuel filter in the outlet of your squeeze bottle, or to
the pump inlet if you use a manual or electric pump.
do not leave your fuel container open needlessly.
check filters periodically and clean them when necessary.
Clean the exterior of the engine with a clean cotton cloth.If
this is not done, oil and dirt will burn onto the outside of the
engine each time it is run and the engine will soon become
discolored.
If the engine is not in use for a while (more than two
months) remove the glowplug and rinse out the interior with
kerosene (not gasoline), by rotating the crankshaft. Shake
out residue, then inject light machine-oil through the plug
hole and carburetor intake, again rotating the shaft to
distribute the protective oil to all working parts.
Gasoline, thinner, kerosene and light machine oil cause
swelling and deterioration of plastic parts, "O" rings and
fuel tubing. Use methanol for cleaning these engines.
Avoid unnecessary dismantling of your engine.

Do not leave raw fuel in the engine at the conclusion of a
flying session: it may cause corrosion. The best practice is
to disconnect the fuel line from the carburetor while the
engine is running. Remaining fuel in the tank should also be
drained off.
