/diy/ - Do It Yourself

The cam follower at the end of the piston goes through a hole at the end of the cylinder. When I insert the piston backwards, it all fits smoothly and slides properly but when I try and install it correctly, the hole for the follower is slightly misaligned with the bore and the piston cant go all the way in easily.

I can open the follower hole a little as it is not critical if it seals but if I make it too large the spring for the valve will not have an edge to push from. Any ideas on how I can get this to work without turning a new cylinder?

In the attached image, the dot in the hole is the center of my follower, as you can see it is out of concentricity by a fair amount.
