Running: The 2300 has been run extensively on many different
prop/fuel/plug/muffler combos. The engine provides the most power
with the least amount of fuss as follows:
Mount engine to permit the tank to absolutely center on the carb
AND have the aft end of the tank at approx. 12" aft from the
spraybar (or less distance). Use the medium glow plug.
And This Is A Must-when selecting any muffler you must restrict
the exhaust if necessary, to permit a very broad easily
adjusted needle. This requires about ½ psi pressure OR about
what you get with the stock muffler and one exhaust outlet.
Set the needle for full throttle, max power. With the model held
straight up-set the idle next with the engine running at
about 2000 RPM to give a clean response. Finally, set the idle
speed. Avoid pumps or regulators.
