How to kill a 2 stroke

#2. Test Amsoil synthetic 2 stroke oil. Use a 60:1 mixture, only mix one gallon.

#3 Run out of gas. Preferably miles from home, and/or anyplace you could convieniently mix up some of that nice Amsoil.

#4 Refill with 50:1 mix of conventional oil.

#5 Decide that the conventional at 50:1 is just as good as the Amsoil.

#6 Go for a good hard run. Preferably ending up miles from home. Always ride with a buddy, but make sure his sled is too small/light to comfortably tow yours, it'd help if his isn't running particularly well either, maybe it should die when it idles.

#7 If you notice the engine making funny noises, be sure to ignore them. Pass if off as belt slap or clutch noise.

Oh yes ladies and gentlemen, I've ruined a 2 stroke top end. Coincidentally now I know what a 2 stroke without enough lubrication sounds like. It goes "ting, ta ting ting" like the sound a loose belt slapping a snowsled clutch makes. Or if you had a screw or something in the exhaust...

Still the Amsoil was good stuff, and I'll try it again once I break in the new top end.

Dealer ship mechanic looked at it and said "let me guess, you have been using brand xmaco gas.

His theory was the alcohol/water content caused the fuel/oil to serperate from the additive/h20.

I use a small amount of extreme pressure/ anti-friction additive in my two strokes one tank each spring.
Run the weed eater wide open all the time. Even after several tanks I can still smell the chemical reaction from the treatment in the exhaust.
