Unable to see the piston you are referring to. Could you draw a circle around it and repost a good clear picture? Those hose clamps are likely to leak. I used to think worm drive hose clamps were the best thing out there. Then I found they weren't. Most cars today have clamps on rubbers hoses and fittings that you have to squeeze with pliers and then slide them off. They are much better than worm drive hose clamps for even sealing all the way around.
On the outside of each carb is a round cover with 3 screws. Those are the coasting enricheners. Behind those covers are a very expensive diaphragm, and a little O ring. If you had a stock airbox, you could use an unlit propane torch just barely opened, and move it around where you think there might be a vacuum leak. The idle speed will quickly go up as it sucks in the propane. But with those filters, it would probably just get sucked through the filters. But you could try it anyway.
OK, I just went and had a look at mine. I think you are talking about the little plungers that the choke linkage is attached to. They move in and out when you move the choke lever, and have rubber seals around them. Are those what you are talking about?
