I have an STS .21D Pull Start for sale. Great power band and loves the MC59plugs w/ a JP-4 pipe.
Engine has about 7/8 of a gallon through it. Upgraded to a bump start race mill and its just sitting around.
PM if interested. Its sitting on consignment at my LHS for 110. It does have scratches on the Cooling Head
but then again who hasn't flipped their Buggy.
