Want to rebuild my 2005 bruin 350. Paid $400 for it. It starts but puts out alot of white smoke. Rebuilt the carb (don't know how to adjust it!) and want to go ahead and put new rings, valve seals etc... I can't find a manual for it and don't know if a grizzley or some other manual will work. Any tips, info or sources would be greatly appreciated. Would like this to be a project for my 16 year old son and myself. Thanks in advance
