Hey guys, Just pulled my head this afternoon to check the condition of everything. I have been chasing a hard starting issue and figured I would open it up and have a look while everything was disassembled. One thing I would like to ask. With the piston at TDC I can rotate it slightly. I can also push it back and forth in the cylinder, on the rings. Is this normal? Cylinder is new from US Chrome. I have never noticed this before and it has me wondering. Please feel free to comment on how it looks. Thanks, George.
