Thanks for the link Slick, have you used/ do you know about that kind of lube Cary ? Thoughts ? When i took the piston out there seemed to be some dust that mashed itself into the piston, or so it seemed. It operates fine so i wasint too concerned, but just incase how much could i get a replacement piston for, if i need one eventually ? I dont mean to take up your time here on the forum Cary, but i figure this info could possibly benefit more then a few people.
