The best method for determing cylinder health is with a "differential pressure guage". It is most commonly used in aircraft engines and can be had fairly cheap on e-bay. The differential guage reads line pressure as well as the back pressure build-up in the cylinder. There should not be a significant difference in the line pressure (usually 75 to 90 PSI) and the pressure being read in the cylinder.
To use the differential guage, the piston must be on TDC of the compression stroke. The advantage is, with the cylinder pressurized you can hear air escaping into the crankcase, pressurizing the crankcase as an indication of ring blowby. If air comes out of the exhaust then the valve may be worn or damaged as well as the seat. Sometimes engines that have been run very lean can have damaged or worn intake valves or seats. With the differential guage, if the intake is the problem then air can be heard escaping into the carb or air cleaner.
Glazed cyliner walls can be caused by engines that have been run too rich for too long. Excessive amounts of unburned fuel can "wash down" the cylinder wall accellerating ring wear and "polishing" the cylinder wall making ring seat and thereby blowby a problem.

If you do this, you may have some carb adjustments to make tho... and some oil on the frame.

Repowering doesnt reduce the value. You just wont get the money out of it that put into it.
I think From a collector standpoint, The value would be reduced if there was a non original engine in there.

im gonna rebuild, ive talked 1 friend into helping, funny thing is hes 12 yrs old, not even kidding. hes got more tools and knowhow then some 30 yr olds. its almost freaking scary. can anyone tell me the best place to buy a rebuild kit? psep has pistons gaskets and rings for around 336 i think (cringe)
I would not discount a young mans ability due to his age. I lost a home to a flood last August, was pretty discouraged to see everything I had worked for, for 40 years under water and I had pretty well written it all off.
My grandson 14 yrs old, waded in 3 ft of water to drag my mower, Snowblower, Weed Eater, Chainsaw, rototiller etc out of the mess, take it home and dry everything out and got them all running.
Some people simply have more natural ability than their age would suggest.
