Brand New 5hp Briggs Engine

I found a brand new short block in the original box for a 30 year old Briggs Engine that gave up a few weeks ago. (pushed a rod right thru the side of the block. This Piston is sealed in the goo that Briggs used to protect it, and It will not move by using my hands and arms. I am concerned about locking vise gripps on it to get the leverage I need to free it up. Any advice out there on doing this the right way? It is a horizontal shafted 5 hp flathead with a 13000 series model #.

Sure the piston rings not locked in place from rust?
Once you clean out the cosmolene it should move by hand if there's no head on it.
If that's the case then set the motor level with the piston facing up and dump in some ATF fluid into the cylinder and wait a day.

there is not any rust anywhere else on this engine, but obviously I can't see the where the rings are just yet. I will go down and pour in the ATF right now.

Thanks for the tip!

I let it soak in the ATF as you suggested, and during the day I removed the flywheel from the old block. I slipped the flywheel onto the shaft and tightened the nut just to hold it on. Piston broke free with minimum effort. No rust no damage. Now I'm assembling everything else to make it run.

Blower will blow the paint off the walls now....I don't remember this blower ever having this much power, (of course it was new over 30 years ago)
