I have an idea for TD engines, but didn't try yet: I'll place an o-ring on venturi threads, so the venturi rises in plastic carb body, when fully screwed and tightened. Because venturi rises, then plastic carburetor body do not crack within time. I meant venturi doesn't force carb body too much from top. Is this right?

Sounds to me like you are installing a O Ring on the bottom on the venturi to provide a soft flexible seal to the plastic threads of the carb body. That may work for a while, but I would be concerned about the venturi vibrating loose during flight, as the O ring might take up the space of one or two lands of the threaded inlet. Maybe if the carb body inlet was bored with a smooth recess, and the venturi had a groove turned on it to hold the O ring in place it would allow the O ring to compress and seal the opening, very similar to what is done inside a Babe Bee tank venturi to backplate seal. If you have the precision machinery to bore precisely the carb body and venturi like those aluminum tanks that Bernie had made, it might just work. .....Or, maybe our member Greg and make some all aluminum carb bodies, then you would not have to worry about the plastic cracking!

Even an aluminum housing without the 1/4-32 thread and a bit more meat on it so a different brand carb would fit, like OS or whatever. Even the Medallion spraybar or a pinch bolt would be nice. Carbs and mufflers are kind of the downfall of the Cox TD stuff which is otherwise a pretty good motor.
