that's pretty cool.Looks pretty good. That dealer is up in my neck of the woods, and to my knowledge is still in business.
I will use a very thin smear of Yamabond 4 there.getting close to putting the engine back together on the SP70. these are basically clamshell engines, though no plastic is involved. this photo is not my saw, I clipped it from another post on this site. I think it's a Stihl but my question is, do I put red dirko HT around the bearings where I marked in blue on the McCulloch?

thanks for this link to your saw build. it's going to be very helpful. and that's a beautiful saw.
when installing new rings in a used cylinder I always cross hatch the cylinder walls with a ball hone in order to deglaze the cylinder walls and give the new rings a chance to seat. I have done this on many nikasil plated cylinders (mostly dirt bikes) and a few with steel sleeves.
having done a lot of reading on ball honing hard chrome bores last night I see varying opinions. I believe the McCulloch cylinders to be hard chrome plated so would appreciate any information on this. if the answer is no, do not ball hone then how do you get the rings to seat?
