well i have been running this one it has a os 40 four stroke
Wow, amazing!!!!! How did you find parts to fit an O.S 40? (clutch, flywheel, looks like it is pull start) Also any video?
does the ring really matter???
Yes, as mentioned it is like a gasket for the glow plug. If your plug ends up being too long because of the lost spacer, your piston may smash in to the glow plug causing damage.
