[QUOTE="PALMER84ONE, post: 174562, member: 6"] Try jetting, and 32:1 Yamalube premium pump gas. If the seals are done you will find oil on the ignition side, and it would run like crap. You can check the bearings for slight movement by pushing on the crank with a big screw driver or pry bar and looking at it off center to see if it moves. Kind of tricky to see, and don't leverage off anything fragile with the prying tool. [/QUOTE]
