Dear all
I have just bought a STS .28 engine for my monster truck. I would like to dissemble the engine for cleansing or porting works. Upon removal of the cylinder from the engine block, I found that there was no cir clip at the end of the piston pin facing to exhaust port. I have also tried to slide and remove the con rod from crankshaft. But unsuccessful

....how to dissemble the STS .28? Thanks you very much
