lf your motor has a poor performance check the following points:
Completely open the throttle twist grip and pull the starter rope a few times. lf after this the engine does not start, c l e a n t h e s pa r k p l u g o r a d j u st th e sparking plug electrodg gap, which s h o u l d b e 0 , 5 to 0 ,6 m m , lf it is obvious that the fuel does not enter the carburettor, it is necessary to clean the entire fuel system. Troubles with starting the motor may also be caused by small quantities of water in the carburettor float chamber (clean the carburettor), or else by moist or salt deposits accumulatedon the ignit i o n c a b l e a n d i g n i ti o n ca b l e p l u g ( w i p e dry with a rag).

To protect all moving parts of the motor against rust, if the motor is to be stored for a long period, clean all outer parts and surfaces especially if the motor had been used in salt water. Use a soft rag, or sponge and water. Remains of salt water within the motor should be removed by means of running wa ter. In ne r walls of m ot or leg should be washed out. For this purpose put the motor, with its lower unit into a fresh water tank and run motor for 5-10 minutes under full throttle. You can also f lush out the motor leg by means of water circulation. Water is directed into the motor Ieg by means of a hose connected to a tap and iiked to the water inlet situated under the anticavitation wing, F ig. 2/2 0. lt is most im por t ant t hat during the flushing out by means of a hose the motor stands in a vertical position, so that the water can f ind its way out through the exhaust outlet. After flushing the interior let the engine run out of water for B-4 minutes at quarter throttle to dry.
