Hi AJ,
When the clutch is engaged you should have no pressure whatsoever applied by the clutch fork and just enough clearance between the cone, pad and fork for free running, but nothing great either. I think that if you've had the engine off then you have a slight alignment issue with the engine being slightly off dead centre, thus the cone is ever so slightly grabbing the cork. This is always an issue when new cork is installed as the cork is at it's maximum thickness and rather grippy until it gets a tad glazed off with usage.
The other issue could also be a slightly worn end of the PTO transfer shaft where it is meant to fit snuggly into the thrust bearing and with some slop it will allow the PTO shaft and associated parts to be able to oscillate inside the bearing and create some grab in the clutch area. But first I'd look at your alignment.
The other thing I noticed was that your primary chain is probably a tad loose and requires a bit of adjustment of the slide block to reduce this somewhat. Not too much though as many folks seem to run their chain too tight and this then presents a whole lot of other issues.
Cheers,
BB.
