I was adjusting the free pedal and noticed that bolted to the inside of the frame is a U shaped bracket. On the top it has the spring for the brake pedal to return to proper height. The bottom part of the U has a hole for a spring but there is no spring.Betsy (1951)3100 has had the clutch pedal returning to about 3 inches( +-)below where the brake pedal does for as long as PA and I have driven it.Is there a return spring missing?? I think I see one in the picture on OCMP but black and white all blends in and can not tell.Thanks
