Greetings and intro from Fond Du Lac, Wisconsin! My name is Bruce and am new to OldMiniBikes. I've liked mini bikes since childhood but I'm just starting out at owning one. I have a Wards Cat Duster that I'm fixing up. I would like to get an idea what to pay for a used engine. There is a tiller down the street for 75 dollars with a nice running 5 horse Tecumseh on it. Is that a good price for an engine for a future project? I'll post some photos later of my project. I've been learning a lot from OldMiniBikes and enjoy the various departments and photos. Glad to have found OldMiniBikes!
