Yup, another carb question...

I got it rebuilt and it runs much better than before (yay for me, and thanks Pinhead videos)

But the fuel level in the sight glass seems low when it's running. It's at the bottom of the window. When it's not running it's higher, but not in the middle of the window.

My question is where should it be when running and when not running?

I set the float height but had to guess a bit as mine was a little different than the one Pinhead used in his videos.
 
I had to adjust my float a couple times. Pretty sure it's supposed to be in the sight glass center when running and when the engine is turned off. If it rises after engine is off perhaps you need to inspect your float needle valve.
