Building in some additional length of the tube is a good thing. Years ago, when the roadster was new, the chute barely came out of the tube and then wouldn't blossom. Lots of dead air behind a real Street Roadster.
Bob Stroud came thru with a longer main line and more spring pressure. It wouldn't fit in the existing tube, so we had to take it out and lengthen it. If it still comes out lazily, you can easily fill in the front of the tube. The way it is now, you wouldn't want to stand behind it. It takes at least two people to load it.
