RE: Super Tigre G-75 Piston/Ring Problems
[b]First double check my memory. Assemble the engine without the ring on the piston, after using your "Sharpie" marker to show the position of the ring pin. With the piston at the bottom of its stroke you will be able to see all the ports, the pin, as memory serves, will be fairly close to the edge of the boost port, the port across from the exhaust. Now looking at the ring you can see how to install the ring so gap will be on a solid part of the cylinder wall. I'm remembering the gap as being the way I said in the earlier post, but if putting it on that way would put the gap in a port then turn the ring over and install it the other way around.
Now with the piston out again, set the ring on top of the piston with its notch directly above the pin in the ring groove and the gap positioned in the way you have proven to be correct.Slide the ring slightly over the edge of the piston to where you can push the notched end down to the groove. Then carefully work the rest of the ring into the groove, stretching it a little as you can.
Before you put the piston back into the sleeve oil the ring liberally, being sure to get oil into the groove behind the ring. And you now know to put the ring notch over the pin, and not the ring gap. Haw.
Enjoy your engine.
Bill.
