I own a ford 1700 tcyl. diesel, the engine will ot turn over using the starter. When I turn the key to start the engine, the engine will turn over just a fraction, and then stop. I pulled the starter, and had it rebuilt. With the starter removed the flywheel moves freely. I put a wrench on the balancer, and the engine will turn over going counter clockwise. When I turn the engine cw it will not turn. By the way, I twisted the bolt off trying this. I give up. Does anyone have any ideas as to what is going on with this tractor? Ps. the tractor only sit for about 2 weeks until the last time it was ran. MW
