Wondering about when made... This little gasoline powered unit from CL works great after an afternoon tinkering. Governor holds right at 60hz no load to full load. Preparing for natural gas conversion. Any info on age etc would be great! Planning the simple demand reg with short hose down carb to low pressure region of venturi. Any tips or tricks or warnings? Thanks, Tom
