RE: quadra 50
Hi Gail,
There are two considerations. One is that the rings are usually pinned on the intake side because it is cooler and the junction will wear less then on the hot exhust side. Two is that the relief in the case that matches the cylinder transfer ports may not match the transfer ports with the cylinder rotated. In this case I modify the case to match if possable. If you don't rotate the piston, you may need a new ring(s) because it will have to reseat in a new position. It is not hard to rreverse the piston. A friend can help if needed. Many people have done this due to broken coil mounts as I recall.

The piston is not the same on both sides, the intake skirt is about 1/8" shorter than the other side...
Heat the piston with your MonoKote blower..
