I have found a S-650G for sale locally for $1000.00. It shows 881 hours. The owner said the fuel tank needed cleaned out, but would run. He was able to start the tractor by putting his hand over the carb and feathering the air intake until the tractor warmed up. Once the tractor was able to run on its own it seemed like it was stuck on high rpm (about the セ range on the tach). Choke cable is stuck almost closed, hand throttle lever does not move. Carb? Governor? Fuel supply? Any ideas? This seems like a tough little tractor and comes with a bush hog. Should I walk or buy? Thanks in advance
