OS 1.60fx cline regulator help
Hello everyone i have had this setup (os 160fx w/cline) for a few years, it just recently satrted acting up. when make a positive G turn or change of direction it loses power during the time your in the turn. im not 100% sure if its going rich or lean but it still has a good smoke trail. other than that it seems to run good, the oil from the muffler is clear. i was thinking about picking up a new diapham...

Steven, a few years ago I had a nice visit with Jim Cline at Joe Nall, He said that in the presence of glow fuel the diaphragms get stiff eventually, he suggested replacing them annually. Just take the diaphragm to your local small engine shop and match it up. It's a fairly common diaphragm used in Walbro carbs.

Loss of power equals loss of fuel. Besides refurbishing the Cline diaphragm, I would look for a hole in the fuel line in the tank. Something that might become "uncovered" during the turn or high G maneuver. That would allow a little air to sucked up vice positive fuel flow and cause a bit of fuel starvation. A stuck clunk can do something similar.

The other thing to think about is the Cline Regulator is sort of the same as the regulator in a Walbro carb too. It has a small hole in the cover that allows atmospheric air pressure in so the diaphragm can perform its job. But in a model airplane, as the plane does its aerobatics the air flow across the regulator can change the pressure being felt and it upsets the fuel pressure regulation. It is sometimes worse with cowled in engines too. Usually the folks will put a fitting onto the cover and route a tube back into the fuselage where the airplressure stays more constant and some other folks use something like a pitot tube in reverse too. pe Reievers at MVVS.NL had a big thread or article about it with pics.
