Walbro wyk33
The one I used is on the page listed below as item ZEN518 halfway down page, not sure if a standard wyk33 would do the job or if the venturi size mismatch would be a problem, however in a heli which sat at half throttle all the time it was excellent.

Rob,
I purchased one of these carbs to fit on the OS at some point. I think it should fit on the crankcase okay and the pressure pulse is not a big deal since the OS already has one in the crankcase. I need to figure out how to change the actuation of the throttlearm for plane use.
I saw the response ofyour DLE35 in your video and I think it is an improvement over the stock carb. I can only hope it will improve the OS; to be sure the OS is pretty good now. If it can be improved, all the better...We'll see
