I think you guys are right on.
When I went to NAPA to pick up the new rings, they gave me the standard compression rings (1 for the top two groves each) and the oil scraper ring with the two smaller rings that line the top and bottom.
I think that ring that was in the back of the setup I pulled out(the hexagonal ring) must have been what Lincoln was referring too-a ring that improves tension.
The second, thinner ring on the second groove must have been to make up the distance in the groove because it was much smaller in width than the new compression ring. The new compression ring fits snug. The old one jumped around alot it there.
Perhaps there was more to not having compression on the engine than a simple valve job. Perhaps the rings were bad as well.
Thanks all!
