Quote: Randy, my new-style continentals/steel don't seem to have the lock/set screw for the rocker pin and other than one bushing you replaced awhile back I don't seem to be having problems.Lear31A's cylinders look like the older style bosses? The orange bases are throwing me off...[/quote]
Lear's cylinders are not Superior brand. They are the traditional early cylinders and the orange does identify them as chrome bores.
The lock/set screw on one version of the newer cylinders was a problem. It held the shaft in one position and the rocker bushings and one side of the pin took all the abuse. A floating pin like yours have is the way to go in these engines.
