I would show you a pic, but my wife run away with the camera for a few days. Another method which is easier if you don't have machines, is to screw in a pressure nipple just above the casting in the venturi. Another regular needle valve can also be used, and just solder up the end with the needle, or set it very rich. Is the XLS .36 a quick motor? My XLS .15 is pretty good, I had been thinking of making a fast combat just for something to try. I have lots of .40's I could use, just wondering.
I pretty much thought about the same thing but i don't have the tools, to make it happen that wouldd be right.I will try the pressure nipple on the venturi, and i didn't want to pay for whole needle valve assy.But i may have too.And i don't know anything about the XLS 36.But i was thinking of putting it on a combat wing of some sort, need to build it.
