Clutch action does not sound right, clutches can stick when left unused for several months but not every time. Might be your clutch cable is sticking.
I'm at the carb tuning stage with my 350 Ben (next week as going away till next week) - tuning seems basic. Have a look at page 60 in the workshop manual (in Ash's dropbox)My clutch was dragging a bit too but not test rode it yet - have adjusted most of the drag using the screw and nut adjustment.I think Ash may be the man to ask!

My carbs were in a bit of a state when before I cleaned them up so could be something else, just don’t know what.
Had a go at settings on mine yesterday too Ben. Running awful really. Similar issues to yours. Balanced the carbs but slow to return to idle. Got good compression at 160 on both cylinders. Going to recheck all settings, check for inlet leaks.I'll report back too if any progress Sent from my moto g(50) using Tapatalk

Only occasionally though, most times it returns to idle quickly, but a quick blip of the throttle returns it back to idle, sticking slide maybe?Frustrating thing is I would have liked to work on the carbs this week but with the inspection on Friday it’s probably best to leave the bike fairly complete. I’ll have most of the weekend to work on them and try making changes, I will try to make one or two changes at a time to narrow down the issue.I will investigate for air leaks probably Wednesday/Thursday since I can do that with the bike together. And also run it to see if the timing/valve adjustment has had any effect.Bu yeah please keep updating, no doubt we won’t be the first or last to have these issues, on other forums posts aren’t followed up with results so become a bit difficult to pin point potential problem areas.
Carb diaphragms maybe, was one on here a while ago with that problem, ds does pattern ones when in stock but aint cheap
My 350 always had problems with sticking slides, I've owned and ridden one for 40 years and they were always trouble, especially in wet weather. Sometimes they were happy and other times they were a pain. In my opinion the carbs on these are not a great design so I changed mine to slide carbs (Amal concentrics in my case), i.e. non diaphragm, and it transformed the bike. I know that is no good if you are after authenticity but in all honesty it is a vast improvement. It runs brilliantly and throttle response is instant. I would say it would depend on how much you want to ride the bike.

Always seem to hole for no reason..
