Tired of the spring binding and crunch sounds i decided to open up my Happ competition. After looking over it it and seeing what makes physical contact i used a synthetic based lube gel. I did the pivot at the top and the cylinder inside after removing the bottom plate the cherry switches are attached to. I also used a lighter synthetic oil and placed a thin coat on the actuator. This stick is as smooth as butter. I even lightly coted the spring and now there is no binding anymore. I dont know if this was discussed previously except for Sanwa and Seimitsu sticks, but i thought i would share.
BTW i used Super Lube oil and gel. They can be found at ACE hardware store’s. One of the finest lubricants IMO, and it wont attack plastic or nylon parts like petroleum based products.
