Lever changer clanks about/marred finish, used heat-shrink.
Wanted to cut back on (tiny) binding here:
So cut a delrin spacer for here:
This lifts the cocking arm up just a fraction to essentially eliminate any slight catching. Pump resistance increases just a touch, but because it is delrin it does not become rough/binding or anything like that. Slightly heavier but smoother stroke as a result.
