Another Massey 65

A friend of mine bought some property and it came with a Massey 65 gas model sitting in the barn in a fair state of disrepair. It is missing the carburetor, the combination intake exhaust manifold is cracked rather badly and the fuel tank is removed with the mounting plate under it missing. It has a radiator that is not close to original requiring a new one if it is worth it.
I forgot to get the serial number off the dash, but from a cursory inspection prior I "think" it was a 1963 model.

He wants to restore/get it running. I think this will be a rather long term expensive project requiring more than a few salvage parts. And thats if its determined to be worth it.

After some inspection I decided that the first thing to do would be to check compression to see if its going to be worth it.
My plan is to check compression dry and then wet to get some idea of condition before ordering a slew of parts.

Book says compression for the G176 Continental should be 145-160 psi at cranking speed.
How much can it be off this and still be considered ok?
 
Don't know the specs but if its been setting like one 35 I own it initially only had 80 lbs but checked it the other day after many hours of use and compression was up past 130 on all. I suppose the rings or valves could of been stuck or corroded.
 
Thank you.

Yes its been sitting for many years. We're going to do the dry/wet test Thursday, and I expect quite a difference due to the time its been sitting. At least it has been in the dry. So I guess we will see what the test says. I'll report back with numbers Thursday.
 

I went over and did a compression test.
I did not do a blowby test to check valves, but I would guess they could use some adjustment.
It has been sitting for years and will need roughly 5-600 in parts before it can run. The carb is missing as well.
Keep in mind it is a free tractor.
What do you guys think?

Results as follows
** Dry Test *** Wet Test
#1 105 psi *** 165 psi
#2 110 psi *** 140 psi
#3 110 psi *** 180 psi
#4 130 psi *** 185 psi
 

I forgot.
Serial number SGM 665591 puts it at 1959.
Continental G176 number 18832.
S = Low Clearance
G = Gas engine
M = Dual, regular transmission
