i dont think i would be so overly concerned with the carb, other than, just running it dry then prime the fuel bulb till, it is dry as well. The thing that i DO believe would be wise, and that will not hurt is to remove the spark plug and put a teaspoon of good 2 cycle or marvel mystery oil in the cylinder and rotate the engine with out the plug a few times to get the oil all around. replace the spark plug and youre done. The next time you run it it will smoke a lot at first but, you will know all has been well protected while in storage.
