Yes there is. However I didn't realize that the projection that fits in the slot of the slide was relatively soft plastic, and I think I've scuffed it enough to cause the drag--and using a Sharpie marker to see where the drag is confirms that the drag is in the slot rather than along the diameter of the slide.

According to the diagrams I've seen the slot that goes all the way through the piston should mate up with a tab inside the carb. I can get it to line up, but with what seems to be excessive friction--it doesn't freely slide, and I doubt the spring has enough strength to hold it shut. What can I do to fix this?
