How old is the chain? Could it be worn out? Maybe that adaptor on the front sprocket isn't centred?
It's getting really close now mate, The cool thing about seeing the light at the end of the tunnel is you just want to get the thing finished and progress happens in leaps and bounds. There's still plenty of nice riding days left this summer!

Just thinking it thru logically, with everything else you've checked like them running true, the only thing I can think of is that one of your sprockets is not a 'perfect circle' ie. that it is ever so slightly oval somewhere, or off centre. Could that be a possibility?
If it's a possibility, is where a way to check that? ie. running something out from the exact centre of the sprockets to the outside diameter, sorta like dividers but would need to be something that worked for this situation...? Or measurements from centre?

maybe try spinning it & try observing what is 'different' when it hits the tight spot; & maybe play around with moving it right on the tight spot & see if you can see what's causing it? may become evident as you keep looking.
you can always use my way...pray

Mike Ive never owned a bike yet that didn't have a tight spot somewhere in it.
The trick is to adjust the chain at the tight spot for the correct chain tension mate.
Hope that helps. scratch

What do you mean by a tight spot?

Could it possibly be just a faulty new chain? If the inner Orings are off in one of the links it can bind and go funny.
