Man, you work on things exactly like I do, but the difference is that I would have not realized about the gasket being off until I had assembled everything and it ran like crap!😂
What is that black hose at 11:50 that disappears into the depths of the engine? I notice mine came off at the carburetor and there was some sooty-looking stuff in the area all around where it was detached. The engine sounded a little weird but was running fine. I wiped off the area and plugged it back in but I can't figure out what it's supposed to do, since it's not the air or fuel intake.
