2021 Turbo Motor Blown?

[nostpete]

Unloading my 2021 Turbo last night and it started OK but shut off in a couple of seconds no weird noises or anything. Tried pulling it and it will only give me 1 compression thump at a time. Let it thaw overnight pulled the belt, clutch seems to turn easy enough but same thing. Any ideas?

Compression test, maybe it turned a ring and caught a port. Seen a few 850s that happened to. Ring pin retracted into piston.

Not sure. I am a big believer of warming sleds up before moving them though, especially in reverse.

Was it the first start of the year? If so, change the plugs and try again.
