For two strokers:
empty the fuel tank and unhook the fuel line from the motor. Apply glow to the motor and turn it over with your starter to remove any remaining fuel from the motor. Put about 10 drops of afterun oil or Marvel Air tool oil in the carb opening and turn the motor over about 10 times. Remove the glow plug and shoot about 10 drops in there also and put the plug back in.
thats all I have been doing and it works fine.
For four strokers:
Ask some else
Ten drops? Doesn't sound like enough to do much. When I know I am storing them for a long time I put a lot of 3 in 1 oil in them, not 10 drops, probably closer to 100 drops of 3 in 1.
