If you do heat cycles don't use a propane torch, use a hot air blow dryer.
All else has been said.
See you next week for an update!

I have heard of people adding a zerk fitting to an old spark plug base, installing the ex-plug in the cylinder and pumping grease in to create pressure on the piston. Any thoughts?

I have used this method on serval as motors , it works awsome until the piston clears the exhaust port , IT WILL move stuff , think about how you pump up dozer tracks with a grease gun , that requires alot of pressure , it will get the tracks so tight they cant flex at all , so this said please soak for a long time then try this method .
I welded a coupling that will accept a grease fitting to a fitting that you use in a spark plug hole so the blow by oil in the cylinder will not foul the spark plug , i will try to post a pic of my contraption..

I feel your pain.....hey I just bought a brand new earthquake for $35 delivered to my door....why do we do we mess with this old stuff.....:msp_scared:
oh cause we love it....have a Poulan 8500 that I will take to my grave....(wife will sell it later at a yard sale foe $20)

I have used this method also. You can develop a tremendous amount of force, without the "shock" load that striking can produce. IIRC, a handheld grease gun can produce aroud 1500 lbs of pressure, mutiply that by the size of the bore....you can see what kinds of pressure you can make.
Can the spark plug threads stand up to these pressures ? I was just wondering ...
Yep, but be sure to remove the cylinder bolts. LOL
