No the cylinder doesnt wear out...its the base that the two screws hold down. Once the base is wore, then they vibrate on the valve area of the cylinder, and thats what makes them break.
The guillotine shaft goes thru the base...if you look at the base youll see theres a oilite bushing in there. On used guillotines you'll notice wear to the coating, but the main problem is the base.
I was lucky enough to buy 2 sets of new OEM bases and valves before they were discontinued for my personal machines...but they still leak.
The reason why mine leak? I run premix, and you have far too much oil that doesnt burn at lower RPM.
I have come to the theory that unless the valves have chunky sludge on them and move freely, they dont need cleaning. To me it acts as a buffer so the valve cant vibrate.
