Ok my evil father-in-law just gave me an old Ted Williams 5 hp aircooled outboard motor. It says Tecumseh on the "flywheel" which comes to my first question- HOW DO I GET THAT OFF??? There is no spark on the plug. Seems to have good compression. I mixed the fuel to 24:1, hope that is right. And what is the gap on the spark plug once I do get a spark? Any help will do or information about this motor. Chassis# 217/58541-1, Ser#6A 021248. Help it really looks like a cool motor.
