So, i think i've sorted the problem. At first i thought it was a bent selector fork shaft (which was brand new), but check it against the previous one, and another used one, they all have some deflection so i think that is normal. I then messed with the camplate again and when i put it back i think i did not have the o-ring fully seated to begin with so it was pushing on the camplate spindle enough to push the camplate slightly into the gearbox and binding the selector forks. I now have the o-ring over the camplate spindle correctly and that is enough to allow what i think is proper gear changes (it won't go through all the gears without rotating the mainshaft and holding the sleeve gear, but i believe this is normal)
Getting that sorted is a huge relief and now on the next issue, the layshaft end play. I measured around 6 hundreds slop and according to the Old Britts write up, i am supposed to shim on the kickstart shaft (Old Britts pic below).

That essentially pushes the kickstart pawl out of the inner cover by the amount of the shim. With 6/100s to shim, i'm thinking that's a little excessive and am wondering whether to shim on both the kick start shaft as well as the layshaft after the 1st gear (just before the kickstart shaft). This would push the kickstart pawl out of the 1st gear by the amount of the shim. So by doing both, roughly 3/100 on the kickstart shaft and 3/100 on the layshaft, i'm moving the kicstart out by 3/100 and moving it out of the inner cover by 3/100s.
Has anyone done this (shimmed the layshaft)? Or any thoughts on doing this
