    Piston Kit/Cylinder Numbers

    How important is it to match them up correctly? And how much does honing a cylinder change it? I ask because I had to order a new cylinder and didn't even think about the number of the cylinder. I ordered my new pistons before seeing that I would have to order a new cylinder and now my new cylinder doesn't match up with any of the kits I have. My cylinders are 12, 4, 16 and I have two "A" kits and one "C" kit. I have been told that its such a little difference that I don't have to worry about it, but I also read from googling the part number of the piston that someone just guessed on the kit they needed and I guess the piston got stuck to the cylinder wall and shattered (but this was on that other site...so yea). Does honing them change the cylinder diameter much? Should I just measure my cylinders after they get honed and go from those dimensions?

    Do a search, there are four groups of pistons and cylinders. The number stamped on your cylinder corresponds with the size.

    Well I def wouldnt go any tighter than the one it calls for, that's for sure. One of the more experienced guys here would have to chime in on whether its okay to go a few sizes too small for the jug.

    I got an answer from one of my other threads, thanks And the kits I have are 1 smaller then the cylinder calls for, so it won't be tighter
