check and see if you sheared the key on the scavange pump gears, also did you lap the check ball in place and check and see if the seat might have a spot where the ball doesnt seat. make sure u dont steatch the spring longer to compensate cause this doesnt work well. if ya did get a new spring and make sure you use the setup from the manuel on setting pressure

Butch, If you need any parts to try out give me a holler. I have the engine out again. If you want to try another scavenger pump.

Take the camcover off and check the Flutter-
valve. It´s the most common problem on the
U and W engines.
