If Buck's motor doesn't pan out try **** or an American parts supplier. If you can find some one who can pack frugally and ship via US postal service you can beat the high shipping charges. Go for a small box. Even if you buy an engine to convert you have most of the important converson parts (mount and prop adapter). If you buy from an individual have them declare the item as a gift it will cut down on customs fees. Even if you have to pay $20 US it may still be chaper than sourcing an engine locally.
