I've got an '84 Tomos A3 engine for sale. I'm replacing it with an A35 and don't need it. The engine has around 3,500 miles on it. It has unbelievable compression, but the tranny is very noisy. For $50 plus shipping, this will make a great engine for someone. The cylinder and/or head are worth the price alone.
Email me directly at email@example.com if interested. Engine being sold on a first come first served basis. Payment by money order or PayPal.
