Hello folks, the problem i am having with my tractor is as soon as i release the Clutch/Brake Control Pedal the engine cuts off. If i leave it running with the brake pedal engaged all is fine. The tractor starts up and runs just fine. Even though it is an 8 year old tractor it has been used for less than 100 hours. It is fully tuned-up with no excessive vibration. Any ideas. Thanks for any help.
