There's nothing to think about here. Engines won't run without air, period
If your carb barrel is closing 100% of the way, and it still runs, you have an air leak.
I had a Magnum the same way. I had to re-seal carb, backplate, and needle valve to fix it.
You might give the RTV idea a try. If this is a drawbar type carb holder, you may never
get it to seal with O-rings alone. (Carb or intake may be slightly damaged)
Also, slip a small length of fuel tubing over where the needle valve screws in, so
it's half on the needle, and half on the housing. That will eliminate this common air leak.
