What happens when a 372xp crank spreads

[Rich Fife]

Rebuild on a build.
My Buddy bet me I couldn't get the saw running from a broke down state in 1hr...

I missed it by 3 or 4 minutes... I had to run out to the garage, dial the piston in and cut it.

I buttoned it up, took it to the garage and ran some heat cycles through it.

I thought I had a video of it blowing up...
Maybe it's on the laptop.
Here is the aftermath...

During the build/rebuild process.

I machined an adjustable v-block so that i could check my cranks for run-out... the 372xp crank ended up having .025" of run-out... we dialed it in to what I would assume is oem specs... just guessing on that. Most stihl cranks I have checked are .0002" or less.

Back together... is it a 365 or 372?
