Yes that is a word for the wise, thank you, fortunately for me the OS 70 4 stroke has the Carb behind the motor and is upside down while the motor sits upright, so I am spared the horrible task of cleaning out the inside of the motor, I have never used a carb filter ever in my life, (more pilot idiotsy) and I sure could have used one more then 100 times over the years, for I have planted many motors around NY, I'm surprised O.S. Trees haven't started growing by now.
