Began by checking the ring gaps... Lubricated and installed Pistons for cylinders #2 and #3. Lubricated, staggered,compressed the rings and installed the cylinders. I chose to install cylinders #2 and #3 first because they share the case through bolts. This way I can maintain the case center torque force while I wait for the other two cylinders. Lubricated and installed the tachometer shaft.
