RE: 52 cc tuning problem

Could you post a picture of the baffle you made around the carb? I have a DA-50 in a WH 300LX. It burbles almost exactly as you descibed your Sachs.
When flying upright and level at 1/3 throttle, the burble (or blubber) is very prominent. When I turn the plane inverted at the same throttle setting, the burble goes away completely. The carb low needle has been leaned for the best transition with high side peaked and backed off slightly. No burble on the ground.
Also, I spoke with a Rep at Desert Aircraft today. He suggested the carb plate mod. DA is also selling them now.
