● ● ● ● ● ● ● ● ● ● ● 3 absorber. Otherwise it is probable that vibration could rebound back to the engine and serious damages may occur during the break-in period. For your safety and the safety of others, please do not stand in front or in line with the propeller when the engine is running. Keep onlookers away from the running engine, especially small children. Always use a balanced spinner and a balanced propeller.
● For optimum performance please use fresh or recently purchased 93 octane gasoline (87 octane gasoline will suffice) with a 30:1 gas/oil mixture. GAS/OIL Mixing Guide 1 Gallon Gasoline(128 fl oz/3.78L)/2-Cycle Oil(4.26floz/125.68ml)=30:1 ratio ● Always install ignition system kill switches on the aircraft used. ● Do not install your throttle servo or kill switch servo inside the engine compartment. Doing so could cause radio interference.
● To avoid permanent damage to the electronic ignition systems, NEVER rotate the propeller on your DLE engine with either of the electronic ignition systems switched on and the plugs not installed in the plug caps. ● If you elect to not use a smoke system with your engine and aircraft, the two included brass fittings must be installed in the muffler and then obstructed to prevent exhaust from leaking into the cowling.
3. Connect the ignition kill switch leads to the red connector from the ignition control module using the lead from the kill switch or with the included three pin connector with pig tail. Use the included three pin securing clips to secure the connections. 4. Connect the ignition module batteries to the kill switches. Any two 4.8-6.0V, 1000mAh and above capacity batteries will work well for this. Use heat shrink tubing to secure this connection. 5.
between the modules and the mounting surfaces and that Velcro® is used to hold the modules in place. 10. Secure all connections with heat shrink tubing (not included).
Installing the DLE-222 on Your Airplane Note: The DLE-222 must be installed on at least a 1/2" [12.5mm] firewall. The firewall must be securely glued to the airplane. Use triangle stock and pin the firewall with hardwood dowels to reinforce the firewall glue joints. Never install the DLE-222 onto a firewall thinner than specified because it may fail due to the power of the engine. Note: The distance from the firewall to the propeller washer is 11" [280 mm]. 1.
plug on the fill line. It’s a good idea to add an extension to the vent line as shown, that goes up and to the rear of the tank. This helps to avoid draining fuel from the tank when the model is pointed down. 4. Install the throttle servo at least 12" [305mm] away from the engine. Make sure that you get both carburetor’s full range of rotation with your servo travel. Be sure to use a non-metallic linkage with the included 6-32 link.
on both sides of the propeller, drill only half way through the propeller with the 13/32" (0.406/10.31mm) drill bit. Then flip the propeller over and drill completely through the hole. 3. Next, set the engine at the beginning of the compression stroke. Note the position of the ignition magnet with engine inverted. 4. Place the propeller on the crankshaft at the one o’clock position. 5. Mark the location of one of the outer holes on the propeller.
drill only half way through the propeller with the finishing drill bit. Then flip the propeller over and drill completely through the hole. 7. Use one of the 655mm SHCS with 6mm lock washers and flat washers to align the propeller washer on the propeller and use the Dead Center Hole Locator to mark the position of the remaining holes. 8. Drill the remaining five holes in the propeller using the same technique as step 6. 9.
Idle Adjustment Turning the Idle Adjustment Screw (No.3) clockwise will increase the idle speed. Turning the Idle Screw counter-clockwise will decrease the idle speed. Low Speed Needle Adjustment Turning the Low-speed Needle (No.4) clockwise will lean the fuel/air mixture at low speeds.Turning the Low-speed Needle (No.4) counterclockwise will richen the fuel/air mixture at low speeds.
Solution: The low-speed needle “L” is too lean. Open it up about 1/8 of a turn and try again. Problem: If The idle is not steady. Solution: The low-speed needle “L” valve is too rich. Close it 1/8 of a turn and try again. Problem: If Engine stops at full throttle. or Engine hesitates when accelerated rapidly. or The engine will not come up to full rpm at full throttle. Solution: The high-speed needle valve “H” is too lean. Open it up 1/8 of a turn and try again.
4. Switch the ignition switch to ON. 5. Flip the propeller counter clockwise several times briskly, until a popping sound is heard. This indicates that the engine is firing. 6. Move the choke levers to the OPEN position. 7. Set the throttle to a high idle. Set the propeller so that it is at the beginning of the compression stroke. 8. Flip the propeller through compression rapidly. If this is done properly, the engine will start after several brisk flips of the prop. 9.
Symptom Engine does not fire Engine starts, then rpm increases till engine cuts out Diagnosis Fix Ignition battery voltage low Charge or replace battery Battery wires faulty or loose Replace wires or Re-connect/check connections Faulty spark plug or not firing Replace spark plug or check for spark * Engine flooded Remove plug, disconnect fuel lines, rotate prop to remove fuel Fuel not reaching engine Check for: a) fuel in tank b) fuel tubing cut, blocked, or kinked c) carburetor clogged * Thi
sure to secure all connections and to secure the Digital Tachometer or leads on the aircraft used. Engine Maintenance Please clean the fuel filters in the DLE Carburetors periodically. Failure to do so may result in miss-calibration of the needle adjustments. In order to do this it is necessary to remove the Phillips head screw which secures the carburetor filter cover and the carburetor filter gasket. Use only carburetor cleaner to spray around the opening of the filter.
