[QUOTE="Tazza, post: 97344, member: 82"] That compression is very low, it should be 427 - 469 psi. The shim is needed if the piston to head height is too low from when the top of the block is machined. You can measure this clearance by putting a small piece of lead solder in the cylinder, put the head and gasket on and cranking it over by hand, you then measure the thickness of the solder. Have a look at this: [URL]http://users.tpg.com.au/tazza_/Kubota/Untitled4.jpg[/URL] [/QUOTE]
