Gas Powered RC
RC engines that use gasoline operate much like chainsaws and leaf blowers. If you treat them properly and set them up correctly, they will run reliably. Gasoline engines come in a variety of displacement sizes, and all of them are easy to start and are user-friendly. It's important to set up the throttle linkage so the carburetor opens and closes completely over the entire throttle stick’s travel. Avoid having carburetor fully open prior to the throttle stick being full power. Should your engine act up and run erratically, land immediately or, if on the ground, don’t take off. Make sure that all the screws and bolts for the carburetor and muffler are tight and then check your fuel lines, filters, and carburetor.
NO BREAK-IN NEEDED - The best thing about gasoline engines is that they are designed to be run without first having to be broken in, unlike glow engines.
PROPER FUEL MIXTURES - As with any 2-stroke, you need to mix oil into your gas. Typical mix ratios are from 25:1 to 50:1, depending on the oil used. Follow your engine manufacture recommendations.
CARBURETOR ADJUSTMENTS - Don’t run any RC engine lean! Set the top end for maximum rpm without going too lean in the fuel mixture. For the idle adjustment, adjust the idle setscrew for a slow and reliable rpm while maintaining a smooth transition to full power.
SPARK PLUGS - All they need are air, fuel, and spark to make them come alive.
PROPER FUEL LINES - Always use fuel line specifically designed for gasoline. Even when using the correct type of fuel line, remember that, over time, they will become hard and lose flexibility.
