OK, guessing the ring that overlaps it self is the top ring.. also "dots up" will start filing top ring.
any advise is greatly appreciated

youtube is a wonderful thing.. took me 6 videos to get the exact answer i was looking for, but got the rings on ...

back to the piston, with some force i could press my pin in the rod and piston, (with my hands) but there is no clip to keep it in the piston, and no cut out for a snap ring to set in.. do i have to worry about the wrist pin sliding to one side and cutting into the cylinder wall????

What kind of piston do you have? All of the briggs pistons I buy have the clips to retain the in the box. Burris pistons come with them too. Also the top ring is the one with the silver edge. The second ring should be all the same color.

Yes you have to worry about the wrist pin moving.
If there are no circlips and no grooves.
It must need buttons. I have cut some from nylon with no issues, ie: cutting board .
Think faster motors has them.

Stick closer too .004 tight will butt up and score cylinder.

Do you have the dome piston Fastermotors sells? Those and the Havoc pistons both use HDPE buttons instead of clips to hold the wrist pin in place, which I like alot more than the clips, much easier to get the piston off the rod that way
