I purchased a vintage racing kart that has a Mercury-Diston chain saw engine on it. It was raced in Connecticut in the early 1960’s. I bought it from the original owner. Rather than converting it to a more conventional engine of that period (McCulloch, West Bend, etc.), I’d like to keep it as purchased. It’s very unique. The owner made his own intake manifold to accommodate dual Tillotson carbs. It also has rare after market GEM mufflers. I’ve taken the engine apart and it’s in good shape. I’ll have to go through it thoroughly before trying to start it. I’m going to need gaskets for the cylinder base, magneto, intake and seals for the crank. Does anyone know of a source for these? The only identifying # on the engine is SKD1438DX, Type FM (Fairbanks-Morse). The magneto is marked as H2B70A, A240851. Any help would be appreciated.
