Engine cant idle

[nennedk]

What's going on here? There's no problem in starting the engine (after a couples of priming), but it keeps dying soon after as heard in video 1.
I can keep the engine running if I keep it above 1500 rpm.
Video 2 shows how revs is going up and down by it self, before it dies (when the engine is warmed up a bit)

You have a leak at the carb base. You can see it in the video

It looks like the hose is off the valve cover PCV valve.

I think its just some oil liquid shaking on top of the engine

Ha ha, it was the hose. I believe I must forgot to put it back on after I have detached it. Now the engine runs smooth again. Thanks
