Cylinder fins
« on: October 05, 2022, 04:53:57 AM »
I was looking at a saw today and on two of the corners of the cylinder, around 3-4 fins broken. And on that same side between the corners one or two are completely broken off. The cylinder is OEM Mahle. This is kind of more of a project. Just wondering if that cylinder will majorly affect performance in future. The piston looks great in it, I can certainly say that. The fins broken are on flywheel side on a 2171

Sounds like a bit too many. 2 x 4 equals 8 busted fins. A couple off of 1 corner is no big deal, but 2 corners like that and she's gonna run hot.

Rule of thumb used to be no more than TWO broken off. I get leery when I see one broken.
