You'll never guess what happened! ENGINE BLEW UP! Did I do something wrong?

What happens here

This video documents the troubleshooting process for a sawmill engine (Kohler EFI on a Wood-Mizer LT40) experiencing excessive white/blue smoke and unusual engine knocking. The primary issue identified is gasoline contamination in the engine oil, leading to an overfilled crankcase and potential internal damage. The project involves draining the contaminated oil, refilling with fresh oil, and attempting to restart the engine. It also briefly covers the preparation of logging equipment for milling dimensional lumber.
