So I inherited my grandfathers 650 when I purchased his house last year. He passed back in 2011 and nobody did anything with the house or tractor in that time.
Needless to say, the tractor has been sitting for the last 9-10 years in the garage not running because of some issue. When looking at it further after two other family members had looked at it over the last 10 years, I found the injector pump rack seized. I took apart the front timing cover to get it out because of the position the rack was stuck. I disassembled the pump, put all the parts in an ultrasonic parts cleaner, reassembled it and as smooth as new. Replaced a few other maintenance items, belt, hoses, thermostat, fuel filter, oil change, battery, etc.
Bled the fuel system went to start it and the engine decided to runaway. Was able to kill the fuel valve on the filter housing which cause the engine to shut down, luckily.
I cannot figure out what went wrong here. Any advice would be greatly appreciated. The tractor is a 1987 and has ONLY 200 hours on it. I can remember riding on it as a child with my grandfather and would love nothing more than to get her going again.
