Another thing that makes it harder to go by a measurement of the ring is the way the piston is drilled. The piston has a series of holes drilled around the top. These holes pass from the top (combustion side) of the piston to the back side of the ring groove.

The reason for these holes allows compression and combustion pressure to get behind the ring and press it out against the cylinder wall. This gives better overall compression and allows the ring to last longer as it doesn't just rely on spring tension to keep it against the wall.

The key to this is that the ring groove must be very tight, so that the oil in the fuel will cause a very tight seal between the groove and the ring. I would consider keeping track of the groove measurements as well.

Don't come off the throttle untill you see your GOD!

I've never heard anyone reference Back to the Future, The Pricess Bride, and quantum physics in one post. The only thing that might have made it more complete is some Monty Python. Say maybe something about a self-perpetuating autocracy or the blessed cheese makers.

Agreed, replace the ring.

Holy cow dude - you're good. You're the only one who caught my references. Pretty much ever!

Sweet!

I bet this one blew right by everyone but you:

then I clearly can’t choose the wine in front of me

Here's the entire quote from Princess Bride - One of the best movies ever:

Man in Black: All right. Where is the poison? The battle of wits has begun. It ends when you decide and we both drink, and find out who is right... and who is dead.

Vizzini: But it's so simple. All I have to do is divine from what I know of you: are you the sort of man who would put the poison into his own goblet or his enemy's? Now, a clever man would put the poison into his own goblet, because he would know that only a great fool would reach for what he was given. I am not a great fool, so I can clearly not choose the wine in front of you. But you must have known I was not a great fool, you would have counted on it, so I can clearly not choose the wine in front of me.

Man in Black: You've made your decision then?

Vizzini: Not remotely. Because iocane comes from Australia, as everyone knows, and Australia is entirely peopled with criminals, and criminals are used to having people not trust them, as you are not trusted by me, so I can clearly not choose the wine in front of you.

Man in Black: Truly, you have a dizzying intellect.

Vizzini: Wait til I get going! Now, where was I?

Man in Black: Australia.

Vizzini: Yes, Australia. And you must have suspected I would have known the powder's origin, so I can clearly not choose the wine in front of me.

Man in Black: You're just stalling now.

Vizzini: You'd like to think that, wouldn't you? You've beaten my giant, which means you're exceptionally strong, so you could've put the poison in your own goblet, trusting on your strength to save you, so I can clearly not choose the wine in front of you. But, you've also bested my Spaniard, which means you must have studied, and in studying you must have learned that man is mortal, so you would have put the poison as far from yourself as possible, so I can clearly not choose the wine in front of me.

Man in Black: You're trying to trick me into giving away something. It won't work.

Vizzini: IT HAS WORKED! YOU'VE GIVEN EVERYTHING AWAY! I KNOW WHERE THE POISON IS!

Man in Black: Then make your choice.

Vizzini: I will, and I choose - What in the world can that be?

Vizzini: [Vizzini gestures up and away from the table. Roberts looks. Vizzini swaps the goblets]

Man in Black: What? Where? I don't see anything.

Vizzini: Well, I- I could have sworn I saw something. No matter.First, let's drink. Me from my glass, and you from yours.

[Vizzini and the Man in Black drink ]

Man in Black: You guessed wrong.

Vizzini: You only think I guessed wrong! That's what's so funny! I switched glasses when your back was turned! Ha ha! You fool! You fell victim to one of the classic blunders - The most famous of which is "never get involved in a land war in Asia" - but only slightly less well-known is this: "Never go against a Sicilian when death is on the line"! Ha ha ha ha ha ha ha! Ha ha ha ha ha ha ha! Ha ha ha...

Vizzini: [Vizzini stops suddenly,his smile frozen on his face and falls to the right out of camera dead]

Buttercup: And to think, all that time it was your cup that was poisoned.

Man in Black: They were both poisoned. I spent the last few years building up an immunity to iocane powder.

The ring seals due to the combustion gas exerting pressure behind the inside of the ring. It does not take much wear to make a difference. I used to check the YS four strokes with a compression gauge, a five pound loss was a big difference in pulling power, ten pound loss was worn out. Not saying that holds true fo two strokes never checked. Also what Rockohaulic said.
