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. An unbalanced spinner and propeller combination will cause high levels of vibration and may cause the propeller shaft to break.
● The throttle and choke pushrods should be non-metallic. ● If the engine is not to be used for more than a month, drain the fuel tank and remove any fuel from inside the carburetor. Do this by running the engine at idle until it quits by running out of fuel. Keeping gasoline inside the carburetor over an extended period of time will damage the diaphragm valve and clog passages inside the carburetor.
Installation Instructions Prepare the engine for installation 1. Check to see that all screws and bolts are tight. Check carefully for any cracks, broken or missing parts.Tighten or replace any damaged or missing parts before proceeding. 2. Install the silicone wire cover over the pick up lead coming from the engine (cut the excess silicon wire cover) and connect the lead to the pick–up lead from the Electronic Ignition Module. Secure the connection with the included three pin connector securing clip.
three pin connector with pig tail. Use one of the included three pin securing clips to secure the connection. 4. Connect the ignition module battery to the kill switch. Any 4.86.0V, 1000mAh and above capacity battery will work well for this. Use heat shrink tubing to secure this connection. 5. Install the ignition kill switch on the aircraft so that it is easily accessible through the cowling or the fuselage. 6. Install the ignition module and battery securely in the airplane forward area.
Installing the DLE-30 on Your Airplane Note: The DLE-30 must be installed on at least a 3/8” [9.5mm] 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-30 onto a firewall thinner than specified because it may fail due to the power of the engine. Note: The length of the engine from the back on the engine mount to the face of the propeller washer is 6.37” [162mm]. 1.
4. Install the throttle servo at least 12” [305mm] away from the engine. Make sure that you get the carburetor’s full range of rotation with your servo travel. Be sure to use a non-metallic linkage. 5. Install the choke servo (optional) at least 12” [305mm] away from the engine. Be sure to use a non-metallic linkage. 6. Connect the ignition wire from ignition module to the spark plug. 8 7. Install the muffler onto the engine.
8. Cut all necessary clearance, carburetor adjustment, cooling, and exhaust holes in the cowl. 9. Make sure the cowl is secured to the airplane and that the spinner back plate to cowl clearance is at least 1/8” [3.2mm]. Drill and Install the Propeller The easiest way to drill the propeller to fit the hub is to use a drill guide. If you do not have a drill guide, you can use the following method to drill your propeller. Most propellers within the recommended size range have a 0.
4. Place the propeller on the crankshaft at the one o’clock position. 5. Mark the location of one of the outer holes while the propeller is in the beginning of the compression stroke position. Use a GPM Dead Center Hole Locator (GPMR8130) to center and start the hole.
6. Remove the propeller from the engine and drill the outer hole on the drill press using a #35 (.110”/ 2.81mm) drill bit as a pilot hole. Next use a #22 (.157”/ 4.01mm) drill bit to finish the hole. In order to achieve a clean finish on both sides of 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.
Adjustment of the Engine Each DLE Engine has been factory preset. However, higher elevations will influence the performance of the carburetor. To obtain optimum output of the engine, slight adjustment of the carburetor maybe necessary. Engine Functions and Adjustments 1. Choke Control (the choke control should be used when the engine is cold) 2. Throttle Control 3. Idle Adjustment Screw (adjust the idle speed) 4. (L) Low-speed Needle (adjusts the fuel/air mixture at low speeds) 5.
or factory setting of the Low-speed Needle is as follows: turn the needle to the fully stop/closed position and then turn back 1.5 turns) High Speed Needle Adjustment Turning the High-speed Needle (No.5) clockwise will lean the fuel/ air mixture at high speeds. Turning the Low-speed Needle (No.5) counter-clockwise will richen the fuel/air mixture at high speeds.
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. Problem: If Your engine does not reach full rpm. or Carbon build-ups appear consistently on your spark plug. Solution: The high-speed needle valve “H” is too rich. Close it up 1/8 turn and try again.
8. After starting, let the engine idle for 30 to 45 seconds. Open and close the throttle slowly until the engine runs smoothly at idle and at full throttle. Acceleration should also be smooth. If acceleration is not smooth, adjustments to the carburetor may be necessary (see Adjustments of the Engine page 12 – 14). 9. If your engine does not start, repeat steps 2 – 8. B. Electric Starter Starting A 24V electric starter is recommended to start the DLE-30 1.
Engine Troubleshooting If your engine fails to start after the preceding starting procedures please check the following.
Optional Digital Tachometer (not included) An optional DigitalTachometer is available that can be directly connected to the ignition and display the RPMs of the engine. This unit can be installed on the aircraft or used to spot check the Engine RPMs. Do not install or uninstall the Digital Tachometer while the engine is running. Many of the DLE Ignition modules have an additional lead to plug into the optional tachometer.
