This is what I found on my 360 piston. Every time I tried getting it in my cylinder the bottom ring kept catching. Well, check ring gap, checks out. Measure rings, measure the same. Pulled everything off to play with it. That's when I noticed the bottom ring pin was located more in the ring groove than top top pin. As the ring was compressed, the ends could not fit under the pin just enough that it was larger than bore. So even OEM has oddities.

2 years ago I grabbed a new ms391 off the shelf and fired it up. And and while checking the oiler it locked up tighter than dicks hatband. When I finally tore it down the piston and cylinder was trashed from a missing pin for the top ring. They did call for that piston back. That's the only failure I seen on a start up in 18 years

Because Muggy Weld has made a HUGE business designing their rods and flux for soldering aluminum.
I'd love to see you use a yellow brass rod and get it to adhere to aluminum. By the time you start to melt your brass rod, some aluminum alloys will already be liquid goo
Never said it would work out good just to try. What is the melting point on jug material say stihl OEM?
