Looper Quiz

[Gene East]

Are you ABSOLUTELY POSITIVELY SURE those are finger ports????

[Jeff Lytle]

They look like they are directly above the wrist pin hole Gene, what else could they possibly be?

Thinking about it afterwards, I thought it might be the relief area seen on the wrist pin side of some looper pistons. In the pic below, it shows that, but the pistons mentioned before more like finger ports to me.

Now comes the question...............What were they for located where they are?

Here they are:

Jeff, those "ports" above the wrist pin were actually cast-in and were more like big dimples; they were for relief. The finger ports--sometimes called "puff ports" or "boost ports" were cut in the back side of the cylinder opposite the exhaust ports. Somewhere on here, there are some closeups of that piston style. The milled slots were also most likely for relief.
