ring end gap for 066

[underbuck]

does anyone know what the ring end gap is suppose to be for an 066?

I do not know what factory specs are, but I use a simple rule that the gap should be no greater than half the measured diameter of the stop pins.

I checked my service manual and it does not call out the spec that I can see maybe Lakeside has the data,,,, but Ive put about 3 piston kits together in the last two months and if they are the rings that came with your piston they should be fine,,, just make sure that the radii face up when you install them I have not had a problem,,, put in one Stihl piston kit and 2 AIP's.... be sure to lube the cylinder before you assemble, makes sure you point the arrow on the piston top toward the exhaust port and after you have it together turn it over a few times gently with the plug out to make sure it is good...

Good luck,,,

Brand new they are about 1-2 thou per inch of bore... More than 8 in an 066... I'd be chucking them..
