Immediately, please inspect the Upper Drain Plug in your Carburetors! When viewed from the left side of the engine, this plug is seated upright position and located right behind the top of Diaphragm housing. This plug must be tight AND safety wired!! If it is not and it backs out (as happened to me this past week) you may get to write authoritatively about the CJ-6A (or Yak) as a glider. When this plug backs out, the engine stops dead in its tracks, the Wobble Pump and Primer become only nice looking gimmicks in your cockpit.
Several owners have found their plug loose and not safety wired.
I checked my M14 Manual and there seems to be a mistake on the diagram identifying this plug...see below.
Mine was fine & safety wired.
