L.M.Cox carburetor holder

Discreetly did I make up carburetor holders for L.M. Cox Medallion 15 & Tee Dee 09 for transforming throttle valve equipping R/C use. Shaft rotary intake system in these motors makes it possible if throttle valve might be positioned at the points. ENYA throttles are utilized for the purposes because of air flow adjusting screws in slow condition and their smaller shape and weight. Precision Lost-Wax Casting method is invited as before. Also, relatively big splay bar in these ENYA throttle rotating valves make it easier to adjust the adequate air flow amount at highest speed rpm, to put the throat area at the point of their suction capability.  I know it has much to do with the diameter of muffler end point diameter,not so easy to know but interesting. As obtained I a sophisticated device as shown the other day, some accurate datum sampling and analysis would be performed soon. I'm looking forward to test and check the condition with datum analysis.
