Meteor piston circlip clock position

[fossil]

I am about to install a meteor piston in an MS 260 and was wondering what the clock position of the circlip end gap should be.

There is a semi-circular cutout at about 8 o'clock in the wrist pin hole. Where should I position that circlip gap or does it matter?

Thanks for any suggestions.

You want the gap at either 12:00 or 6:00 due to the up and down movement of the piston and changing directional forces exerted on the wrist pin and clips.

Ever since I first started working on saws I've always put the gap at 12:00.

Works fine until you flip the saw upside down!!

Yep, 12/6...either works fine.

Been a service tech for the last 15 years at a power equipment dealership. I cant remember exactly what manufacturer put out the bulletin but it said to position at the 12 O'clock due to heat at the piston face causing problems with temper in the retainer rings. Its always 12 O'clock for me.
