Just for my knowledge, what is the need for a reverse wound spring? I don't think I'm fully understanding.
Another thing is, sometimes it will kinda work. It will accelerate and eventually shift. For some thats good enough but they dont realize the potential upgrade of MORE acceleration and precise shifting in comparison because 'it works' out of the box.CM,
I'm learning also, and not the one to answer with authority, but I'm pretty sure it has to do with direction of the driven pulley's rotation. As a rule, the series 40s are mounted with the springs toward the engine (counter clockwise rotation when viewed from the non-spring side). This more common position takes the regular spring. If you have to mount the driven outboard (a reverse spring is required because you have changed the rotation of the driven pulley.
Don't bank on my answer, 'cause I'm new at this and started this thread because I had the same question.
To complicate the issue, there are TONS of videos with people showing and explaining (what I now think) is improper installation.
