@Moparmyway, do you have a ring layin around from the blue pistons? If so, could you mic one and see how thick they are.

Sure do and sure will, as soon as I get home bud !

Mahle new OEM Stihl MS660 (from my ported EC 066 ) and a pair of Mahle OEM Stihl MS661s ( one brand new out of the box the other with hours on it), also an 056 Mag 2 jug, but he never should have run that combination, that model is old enough we knew it was chrome bore. I have same cylinders and rings headed to a lab to confirm actual composition.
@tree monkey @Redbull661 I sent you guys a sample today but don't run it in a Stihl cylinder.

You tried any in jugs that have been re plated?

not yet Deets, but here is the Wiseco ring which is the same as the Caber 1mm ring and is produced by NPR (nippon piston ring) the biggest ring manufacturer on earth apparently and the only place that makes a standard 1mm ring - it would have been cool to know this back in June when we started looking for a 1mm ring for the 181 full skirt race pistons LOL
Live and Learn - we are sending a bunch of cylinder/rings in for analysis Mahle, Gillardoni, Koblen Schmidt, Meteor, Farmertec, New West chrome and nikasil, as well as the Wiseco piston and ring

Update, just heard back from Reilly that he tried a Millenium plated cylinder and the compression is too low to fire at @150, the same cylinder will fire with a Meteor piston that has a slightly smaller crown

Does anyone happen to have one of these mmws kits laying around for a 064 that they are willing to sell?
