It really sounds like the engine has had it.
It likely has lots of ring wear and cylinder bore taper hasened from lack of oil changes.
Only time I have really seen carbon jamming up the oil rings is in diesels that were not getting the oil changed often enough and were likely being serviced up with gasoline spec oil.
That honda engine is likely so old the valve guide seals are not at all functional.
A quart of oil per day is likely not all due to a head related PCV and valve guide type of problem.
