Re: I5 piston rings



> Am I wrong or should the ring gaps be at 120 degrees?

That's where you should put them when assembling the motor but once it's 
running, they will rotate around and settle in wherever they're happiest.  
The two-stroke motors that I built/raced when younger had a pin in the piston 
to prevent the rings from rotating because they could snag in a port.  (I 
also remember pouring a little "Bon-Ami" cleanser down the sparkplug hole to 
help seat the chrome rings when they were stubborn about this ... those were 
the days!).
