Doodle Bug Scooters in Crosley, Cushman, King Midget, Whizzer Posted November 15, 2012 Thanks Scooter Guy for the quick reply! The reason I asked about the crankshaft size is that mine is actually 1/2" and I found that quite odd. That now raises another question. Since mine apparently is for a washing machine will it work on the Doodlebug if I have it repaired? Does it have similar operating characteristics to the fluid clutches for the DB?
