on the last or bottom hole with the Mod 50 rod and bullet just guna have it TOP pined on the pencil Mark.

So the idea is to make sure the pins and ring gap runs up and down over a consistant surface and not over the edge of tha ports?? Am i on tha right track?????:)
-
yes, you don't want to upset the rings. the gap has to ride on the wall or some what centered in the port. half on the wall and half in the port will never last:eek:, it will just kill it's self in about a hand full of pulls:cool::cool:
you want it so the rings and the piston kinda don't even know the ports are thare, thats guna stay together, ;)
