Then you must have a serious air leak!

Is this on a reed valve engine?

Yeah i check the reed and it is ok

Then I'm with the rest of the answers. It's sucking air somewhere or it wouldn't run with your finger in the carb. You just gota find the leak.

If the carb has a finger in it how is it even getting enough fuel to run...

I was kinda wondering that too. Maybe it's really only a half a finger.
