Took advantage of the sunshine today to get this up on some axle stands on the street and have a pop at adjusting the belt tension.
All went well once I'd figured out how to get it jacked up high enough to get an axle stand in.
The belt adjustment was waaaaaayy out, although I think I may have slightly over tensioned them now. I was pretty excited to drive it, thinking that it may make a massive difference. Although the initial take off is much smoother, sadly the reviness remains. It is slightly better in that overdrive is kind of working, you can feel it change up a bit when you come off the throttle now.
As well as needing diaphragms and a new set of belts (once tensioned you can see that one is a bit more worn than the other), I kind of suspect that something is up with the centrifugal weights in one primary, as at certain speeds it can be a bit jerky, as though one belt is fighting another. It is possible that this could be caused by one diaphragm being worse than the other..
Hey ho.. seems like I'll be spending some coins on parts and spending a few days under it on the street!
I forgot to take snaps apart from this one, but you can see how the adjustment bolt ended versus where it was by the clean section on the bolt.. this takes flippin ages as you can only fit an open ended spanner on and make about 1/16th of a turn!
