Yes Norm that is a serious amount of work you do with that mod, I would need a backup of a dozen carbies before attempting that!
Something I've noticed in my limited fiddling with these is that the couple of replacement diaphragms I've bought seem to be a bit lightweight and flimsy compared with the originals, am I wrong?
Regarding speed, I looked at a workshop manual I found on this forum and it ended by saying something along the lines of " If that doesn't work change the spring under the end cap". It didn't offer any advice on longer/shorter/stiffer or whatever. I tried a shorter one and it marginally brought the revs down.
