Whatever you do with your carb, you are going to need both a high speed and a low speed adjustable needle valve to use the engine on an airplane.
With the Ryobi engine, a choke is a good idea but not so important on piston ported engines mounted without a cowl.
Enjoy,

Seeing how the engine was free, I will just look for a new carb. The engine will be going on the Great Planes Big Stick 1.20. No cowl.
Thanks again for the info, parts numbers and help.
