I've often wondered the same thing! This pig is gross. I plan on cleaning the heck out of it first before ever turning a wrench. I've already ordered te wheel bearings and hope to have the carb cleaned this weekend.  The PO said he mixed the gas and oil at 50:1. My zilla gas is mixed 32:1. Would it hurt to run the same fuel? I run 110 octane and 927 in it.
