The gas pooling in the read block area is not happening, I really thought it was the problem. My problem is with a 3W-150 in a Carden 40% 330. I have flown the thing around at low throttal killed the engine, landed, and checked the gas content-none in the reed block. If you think about this for a while you realize the pump pulse holes are there and the carb wouldn't work if it was full of gas.

I have also put on the elbow and it had no effect, I have even turned it around facing forward, no change. To make this worse I have a 3W-100 in a Areoworks Edge and it works perfectly in every attitude. I just vent the senser to the fuze.

I am increasing the spring length tonight and trying it tomorrow morning, I will let you know.
