Default Re: Old type of 2 stroke

Very interesting piece.
My take: The valve is on the opposite side of the crankcase from the carb. I'd think that it is more apt to be either a compression relief or part of a governor system. The intake appears to go directly into the crankcase, perhaps a reed or even rotory valve. If I see the pics correctly there is another port below the exhaust for the intake. Very cool with the gearbox and all.
I'd treasure it.
