Metering lever should touch bottom of well if pushed down and return to top. The lever should sit flush with the top of the well as in picture and the needle should be completely seated. Touch the tip of the needle and make sure it's seated and doesn't bind. 

Proper kit should be an RK-23HS and parts should look like the pieces in the above carb.

Ideally you should pull the carb off and test the sealing function of the needle with a pop off tester or use a compressor regulated down to 10- 12 or so pounds to see if the needle holds pressure.  If it doesn't seal it will flood.

If the seat where the needle seals is dirty or has been chingered  up with a tool it's gonna be a nightmare to seal. Go through the carb carefully and inspect the seat and needle for function, and test the sealing if you can with low pressure air on the fuel inlet line or the hole in the opposite side of the inlet needle

While you're at it, make sure the tank vent is functional, if it doesn't vent properly it will pressurize the tank and can dump fuel into the engine.  Don't put a different UNKNOWN carburetor in the mix till you determine what's wrong with this one.

WOW.. thanks for all the information!

The lever will not go all the way down, it is like the needle is binding up.

I will take another look, hopefully tonight after work.
