I think Hal is correct about the electric valve being "slower" than the manual valve. Apparently, the electric valve has to have some pressure behind it before it closes. I just inadvertantly tested this theory.
I haven't fired up my engine yet, so I followed the Accusump instruction book procedures for pre-lubing a fresh engine. I depressurized the Accusump, removed the pressure valve core, removed the electric valve, pushed the cylinder down, and filled it with 2 quarts of
oil. I then replaced the pressure valve core and the electric valve. Now comes the interesting part. When I went to pressurize the Accusump, about a half a quart of
oil gysered out the electric valve before it closed! Nothing like a nice
oil shower
Anyone have any suggestions on how to get oil out of one's nose?
