I've got my case together and was checking my deck ht. My readings average from .074" to .080" for all four cylinders without any shims. The problem is I am shooting for .040" to get my compression ratio up to 9.5:1. This is my first T4 build. I have built several Vee motors in the past and never had this problem. Is it possible to shorten the cylinders? I just did a quick measure of the height of one cylinder. It is 3.62" from the case sealing surface to the top. Does this sound about right? Everything was going to well. Something had to go wrong (IMG:style_emoticons/default/mad.gif)
