6. WITH SAFETY IN MIND Use a conventional electric starter with a correctly sized cup for your spinner TIPS amp HINTS FOR STARTING PROCEDURE 1 Eye protection should always be worn when starting and running your engine 2 The crankshaft must be rotated anticlockwise i e the same direction as normal propeller rotation 3 On anew engine or if very cold the engine will feel quite stiff to the turn and until the engine has had a tank or two of fuel passed through it For initial starting purposes we recommend needle should be 2 turns open This should be pre set from the factory At all times ensure that the engine is on a low throttle setting when you start it 1 8 1 4 High throttle will make the engine difficult to turn over 4 When you have set up the starting arrangement as described above you can now start the engine Ensure fuel is getting through to the carb and that the needle is open the correct amount Turn the glow on Hold the starter very firmly but without pressing hard Press the starter button The engine should immediately turn over rapidly and fire within a few seconds 5 Under No circumstances should you keep turning the engine over if it does not fire as this may cause damage to the engine From the earliest prototypes the RCV engine has always been an excellent starter If the engine will not start there is always a logical reason for it In particular check that the glow is adequate and that fuel is getting
