    New Engine Questions

    Just bought a new 80cc engine online. Bought it from ebay, its a basic 80cc/66cc (Jet) engine. Ill post a link to the engine on ebay. I Was wondering if you guys have any tips for me regarding break in or assembly. I was thinking about breaking in with Opti2 at 100:1 but open to suggestions...
