Finally got time to verify timing and valve lash . Why will one pump never ever change in 30 years and timing on another pump will change in 2000 hours ? I talked with the dealer and they run an injection pump shop going to send injectors and pump off and have them gone through . Im sure the injectors are coked to point they are near closed off they were 1500 hours when I replaced them last time can they be cleaned ? This is as close as I can get the timing with undoing injection line clamps to turn the pump farther . At one time I was checking valve lash and pump timing every year but my other tractors never got out of adjustment but this 4 cylinder I guess will have to do one a year . And it still has always blown a flame and so do my other tractors .
