D-7 17a, hyd blade, non turbo. need info on fuel system

Gentleman,

I have had this tractor for approx 10 yrs. we have stored unit for 4 yrs, inside. We are in process of getting unit serviced for use. We, have a miss on #1 cylinder. Checked pressure visual at the pump and the flow appears the same as the other pump outlets. At the injector Nozzle connection appears to have good flow. We suspect injector tip problems. Any ideas how to unclog without removing injector, such as fuel addiitives, etc? we have good compression. Unit cranks very well. This tractor has been and is in excellent shape. Due to high desiel prices we stored unit, now we have timber we must clear and other typical dozer work.

Thanks for any help.

The usual method is to move the suspect injector to another cylinder and see if the problem follows.
