Mounting the Engine Selecting a Suitable Propeller Most model airplane designs make provision for an engine mount. It is extremely important that the engine mount be securely mounted to the airplane’s firewall and that the engine is securely mounted to the engine mount. Follow the instructions included with the airplane for mounting the engine. The engine should be fastened in place with 4 screws through a conventional beam mount. Use 8x32 screws (26GT2) or 10x32 (35GT2).

Choke Lever Pressure Inlet Adjusting Needle H Adjusting Needle L ( directly below Needle H ) Before you first start the engine, make sure that the spark plug is screwed in and tightened and that the plug socket is fitted in place and fastened down properly. Fix the ignition sensor in the proper position above the magnet with the screws enclosed.
After starting and warming the engine for 30–45 seconds adjust as follows: Step I- Move the throttle to 2/3 high throttle position quickly (fast acceleration). Then repeat three times— if the engine accelerates smoothly go to Step III. If acceleration is not smooth go on to Step II. Step II- Faulty acceleration and a tendency to quit is usually attributable to a poor fuel mixture in the medium rpm range. Stop the engine and recheck the fuel feed (the fuel line must not be pinched or broken).
Trouble-Shooting Guide If the engine does not start Mechanical Faults - check and use a new spark plug if needed. (Check the spark: put the plug into the cable end and by turning the engine you´ll see the necessary spark. Note: The plug must touch a metal part of the engine.) - check fuel lines. - check for proper mechanical function by turning the engine over. - check that the carburetor is correctly installed.
