Thanks,
I hope to have the engine back wednesday. I will assemble it AGAIN and hope to have it in and running this weekend.
The bad (old) gas is more volitile and can ignite and explode while in the compression stroke. That exploding gas puts pressure down on the piston while it's still comming up. Then it fires again when it gets to the top when it should. All this creates tremendous heat and pressure in the cylinder. Thats when the ring landings cant hold the ring, and it breaks.
NOW you have more heat and pressure going down the side of the piston, heating the side of the piston and getting in the crankcase. Now you also have pressure in the crankcase hammering up on the ring landings also. Every thing goes to s#!t.
