I believe that carburetor is black plastic and is known as G4. I have a personal phobia about them, but if you can compare yours with that one, and consult that diagram & parts list, you may at least be able to see what is missing. When it comes to making it work, I'm sure one of our forum members who does not have my weak stomach for those carburetors will be able to help you. You most likely will need help: they are no picnic to work on, compared with other carburetors.
