Sloppy piston if measured correctly.
That causes snow ball effect on collapsing skirts also.

Must be one noisey saw!

Not noisy yet but I tore it down because I had purchased it recently. I use bore gauges and a micrometer to measure so I sure hope I was relatively accurate!
20 thou on diameter... so I will change it before I run it again.
