1995 Wolverine sputtering and bogging
My Wolverine runs great when the fuel tank is almost empty. Once you fill it up it sputters and Boggs and may eventually come out of it. If I drain the fuel tank to almost empty it works great. Fill it back up and the problem is back.
I originally thought it was the non-oxy 91 fuel that I had in it so I drained it and ran it at almost empty until it was out of fuel and ran great. To eliminate bad fuel I put standard MN 87 octane in and filled it up and stuttered and bogged again. Drained the tank to almost empty and ran great again.
