Self timer problem in KODAK Retinette 1A

This KODAK Retinette 1A had problem with the sticky self timer. First: set the focus to infinity... Remember to set a mark before unscrew the front lens group, and where the lens come off the focus thread. In this camera, the lens has 2 revolution and a little more to come off, then set a small mark. The self timer do not sit with screws. clean the self timer with Isopropylalcohol 99% or lighter fluid, and lube the axel end with very thin sewing machine oil.
