I'm more than happy to help if I'm not working 
Having seen the issue I'd say it's definitely rings. Stem seals/valve guides tend to let the oil into the cylinder overnight causing a smoky start, this is worse when its revved.
I'd still try pouring a strong solvent into the bores through the spark plug holes and leaving it a couple of days.
