Sep 11, 2014 / B250 McCormick International compression. #1 B blacksmithbill New member Joined Jun 15, 2013 Messages 1 Location Fredericton,NB Tractor Ford 4000 the guage show 30 lbs compression when cold but when warm pressure drops to 20lbs or slightly less. Should this concern me? It starts easily and runs well. I have only had it for 4 mionths and have not sed it a lot.
