The part number for the FT120 carb is 46081029. It's a twin-needle carburator with a small intake. Since the engine is quite old, and Tower Hobbies no longer has parts for it, I suggest that you measure the size of the opening for it, and try to find a reasonable alternate. Perry carbs can be cut to almost any size, so that might be a good choice. OS does provide measurements of its current carbs on its web site, so you might just find a modern replacement. However, if you do, you might need to restrict the throat in order to get it to draw fuel or use a Perry pump for fuel delevery. Most modern carbs are designed with larger throats for higher power output.

Lyman, Thanks for the help, but Tower says they can only provide the replacemant for the Gemini II. Mine is the original Gemini.

You might check out the carb for the still being manufactured Gemini 1.6; it might fit. Mine "looks" the same..

I am on the right track!!! I have found that the carb for an FP 40 will fit exactly and mount tightly. I may look into what a carb for an LA 46 might would work like. Maybe more performance than the 40 FP carb. Thanks for all the help and info.

Unfortunately, that carb is an air-bleed type. I don't know why you don't just buy the Perry carb for the 40 FP. Like I said before, they can be provided for almost any engine. They are reliable twin-needle types. Now that you are certain of the size, the rest is easy. They are a Varsane product. (no connection to me)
