The original linkage setup consists of two plastic bushes and a spring washer, even when new this setup had a lot of unwanted play in it. The linkage will now more than likely be considerably worn, causing the linkage system to feel “sloppy”. There are other kits available which replace the plastic bushes with bronze equivalents but the spring washer design is still utilized, along with the original large shanked bolt.
Only by changing the design of the pivot system (by using this kit) can the sloop be reduced entirely.
