Don't compress the springs and don't use the ones in the kits.


To get the seats in I use a little silicone dielectric grease on the o-ring then just push them in with my thumb, with the needle out.

Does the needle have to sit a around a certain way meaning the Top surrounding of the needle loop where the arm goes through it has a little bit Sticking out on one side of the needle retainer, as should the needle move up and down freely without a slight catch. As for some reason mine is slightly catching when it's lifted the other thing is should these arms be sitting level when installing them
