DLA ENGINE OPERATING-INSTRUCTION MANUAL GS R/C IGNITION TIMING, SENSOR: (How to set the timing sensor) The sensor timing is set at the factory to ~ 30O, and you should not have to reset it; however, depending upon several factors including: altitude, temperature, ultimate tuning for specific application such as racing, you may want to adjust the timing. Be sure to check the sensor screws to be sure they are tight and mark the sensor edges with a felt pen for reference.

DLA ENGINE OPERATING-INSTRUCTION MANUAL GS R/C CAUTIONS: 1. 2. 3. 4. Advancing the timing causes the engine to run hotter. (See Temperature Limits) Advancing the timing typically increases the power…. to a limit. Advancing the timing, may make the engine harder and more dangerous to start. Advancing the timing is harder on the engine and advancing beyond 32O voids the warranty.
DLA ENGINE OPERATING-INSTRUCTION MANUAL GS R/C TEMPERATURE, ENGINE, LIMITS: The engine head temperature should never be allowed to reach or exceed 120O C (248O F) and the crankcase should be restricted to 70O C (158O F). Here is where some temperature measurements and perhaps temperature telemetry would be quite useful. On hot flying days, > 95O F, you may consider richening the “rear” carburetor’s high-end needle and reduce the rpm by ~ 200 to help cool the engine.
GS R/C DLA ENGINE OPERATING-INSTRUCTION MANUAL The gas or fuel tank is typically placed with the tank’s center located over the aircraft’s Center of Gravity (C/G) point, thus assisting in lessening the effect on the aircraft’s pitch-moment as fuel is consumed from the tank. DLA engines have a “diaphragm-type” pump in the carburetor and thus the relative level of the tank’s, fuel exit point to the carburetor’s in-take point is not critical.
DLA ENGINE OPERATING-INSTRUCTION MANUAL GS R/C It is mandatory that you filter the gasoline from the source as it is pumped into the aircraft’s fuel tank. Failure to do so can damage the carburetor and cause engine failure. One may also place an in-line fuel filter between the aircraft’s fuel tank and the carburetor. The inline filter must not restrict the free fuel flow from the aircraft’s fuel tank to the carburetor.
GS R/C DLA ENGINE OPERATING-INSTRUCTION MANUAL Use of propeller sizes other than those specified above may either “load” or “un-load” the engine and cause damage. Un-loading the engine has the greater potential to increase the engine’s rpm higher than recommended or safe for the engine. The prop type and styles may have the same “loading” and “un-loading” effect, so always check the engine’s rpm with a tachometer. ALWAYS CHECK AND RE-TIGHTEN THE PROP-BOLTS AFTER EVERY TWO OR THREE FLIGHTS.
GS R/C DLA ENGINE OPERATING-INSTRUCTION MANUAL ENGINE STARTING: 1. Be sure the Ignition Kill Switch is in the off position, and that your ignition and receiver batteries are fully charged. 2. Add the gas:oil mixture to the fuel tank. 3. Turn on your transmitter and receiver. 4. Make sure the transmitter throttle control is in the low or idle position. 5. With the kill switch in the off position a. Close the carburetor choke b. Turn ignition kill switch to the on position. c.
GS R/C DLA ENGINE OPERATING-INSTRUCTION MANUAL ENGINE MAINTENANCE: The engine exterior should be cleaned regularly to prevent build up of oils, gas, dirt, etc. Always store the engine with the cylinder closed to the point where the exhaust port is closed to prevent debris from getting into the engine. Also, it is good to keep the choke closed for the same reason. Fuel tubing will deteriorate over time with symptoms of hardening, and/or discoloration. It should be checked and replaced periodically.
