can't seem to get this force to stay running. It only starts when I flood it with fuel and dies right away. All back to factory settings cleaned everything and checked for air leaks. New glow plug and checked the clutch for damage. Nothings working. Bearings are good and compression seems to be good. Don't seem to have any. What else am I missing? What can it be? I'm don't with this thing ready to sell it. The engine was pretty new. Previous owner bought it new and broke in properly only a gallon through it.
