Ok, the noises had to do with broken brackets for the lower push rod tube
shrouds, tappets, maybe some subtle exhaust leaks, and some cheap recent
replacement parts.

I cinched up the exhaust fasteners, wedged pieces of wood to hold the
shrouds from vibrating, then addressed the lifters. Added 1/2 quart 2 cycle
oil to the crankcase, ran the motor 10 minutes warm, drained and changed
the filter and oil, added the other 1/2 quart 2 cycle oil. Oversize drain
plug wouldn't hold, brought out the last few rounds of thread. Installed
1.5X oversize plug. This can never happen without over torque. Learn to
feel the crush of the soft metal seal and stop, no more. Lifters now quiet
after driving 5 more miles.

Rumble rumble from bearings of newer wannabe no name loss leader weekend
FLAPS FLYER water pump remains. Not the smoothest sound as well from both
recently cheap reman alternator bearings, same $39.95 loss leader type item
from the looks of it.

Gross black from the initial solvent run proves lots of varnish and tar in
there to dissolve. That's why I don't run them long with the initial shot
of solvent. If it's really heavy in there, it can plug your filter and
bypass chunks to your bearings. All experiments have an element of danger.
I will advise changing the oil and filter again within an hour or two of
hot running. Get the filth out, get it clean and keep it clean inside.
Double your engine life over rule of thumb schedules by keeping the oil
clean by actual inspection. Keep notes!!
