[MR2] Compression ratio

[John Treadwell]

Alright, I will have to get a copy of this book, but if I understand this 
shimmy shimmy process, it involves checking the valve clearance with a 
feeler gauge, and then, if they are off, you somehow, remove the current 
shim for that specific valve, test it with a micrometer, and then replace it 
with a shim that is the appropriate size?
Is that about right?
Thanks,
--John
