Mine comes out as soon as the engine fires up. the "manual" says "plunger must not move in valve body when belt is in high variable speed position with full engine rpm." From that vague description i'm thinking it should always be in. looking at the schematic, when the rod comes out, i'm assuming the ball comes off the seat. I tried to hold it in with large channel lock to test it, I thought i was but the sheave still wasn't holding. quite possible i wasn't holding it in all the way. even with the nut/spring cranked all the way tight it still comes out at start-up. the manual also states if you run out of threads to put a washer under the nut but i can crank it till the spring bottoms with no change so not sure what a washer would do. maybe missing the ball or something, who knows. I know it was suggested to go thru the valve already, i'm just hypothesizing)</p></blockquote><p></p>
