Ok, I'll get back to you on that number. I'm running our standard Gas/Glow mix of one part 10% oil & 10% nitro glow fuel mixed with two parts of high test gasoline. I didn't have to modify the carb, though the needles are turned out quite far. In fine tuning I will likely raise the regulator level just a touch. This then flows more fuel and you can run the needles closer to original settings. I find that on some carbs you need to do this for Gas/Glow operation, some not.

Note to anyone thinking of running Gas/Glow: I always treat my Gas/Glow engines just like a glow engine after running. I run the carb out dry of fuel, and then use after run oil in the engine. It's important for several reasons.
