Now that one I know how to deal with. It could be the needle not seating straight but for me it was something else. Apparently the bodies get a little warped or something. I cleaned up the air piston really good, making sure it was smooth and burr free. The piston was still binding when I put it back together. The secret was to rotate the top and tighten it down carefully. First, play with the torque on the bolts holding on the top, if that is not enough, rotate the top 90 degrees and play with the torque. Repeat until the piston moves freely and the top is on tight enough for you.

With this topic in mind I have one Stromburg that does not work properly. The issue seems to be that the piston does not freely move in the carb body. I have check the diaphram and there are no holes or cracks. Could this be the needle being ever so slightly bent? And how do you tell.

I have several Stomberg CD150's. (Series 5) The way the need attaches to the air valve (piston) is slightly different in each. There is a set screw in the side of the air valve to lock down the needle. On some, the needle then remains fixed with respect to the rest of the air valve. On others, the part of the air valve that the needle locks into moves up and down about 1/8 inch. Therefore the needle moves in the jet. Is this by design or is it broken. How would I fix this? JB Weld (Epoxy). Does it really even matter?
Thanks, Chris
