Welcome 2 GC.
I ended up using Lucas red and tack because that was what's in my grease gun. I had to take the spring off anyways to grease everything so I might as well put a new purple spring on while I'm in there. Right now I'm trying to disassemble the shifter. Too much rust to move smoothly. I can't find any posts of someone else attempting this. I already got the main bar in the bottom off. The bar that the shifter rides on is giving me trouble. Maybe because it's not supposed to come off. Maybe because of the rust. The housing is plastic so I can't use heat. If I can get it off then moving the shifter left to right will be much smootherWelcome from Wyoming. Alot of the guys around here use high temp waterproof marine grease. You can do a shim without a spring. Most people who need the umph add a spring. Personally I plan to do a shim and add a new belt next time I work on CVT.
