That's a great video ! I'm going to get mine running like that too.
Update: The spray as I described it must be a fuel/air mix being pushed out the carburettor by possibly a leaking inlet valve. But compression feels good. So I'm not sure there. It also starts by hand when warm, and runs great.
But things just got worse. In previous runs today I did hear a weird sound from time to time. When I went to run it just now to make a video of the spray I found out what it was. It was the lever that keeps the exhaust valve open hitting the gear. And just as I was running it now it hit it hard and the lever rotated out of the way letting the engine rev up max. Scary. Stopped it immediately, and I'll have to figure out what caused that. So I have two issues now. I have the idea the flywheel moved and this caused the issue. Don't know, I'll investigate tomorrow and try to upload a video.
Thanks so far,
Hans
