Some of you are going to think this is a stupid question but, I'm going to ask it any way.<br />I'am assembling a mcm140,1984 vintage, and I'am<br />at the point of adjusting the valves on the head.<br />The manual has a good explaination of how to do this but, it doesn't identify which valve is which,and they all look the same from the top.<br />Could someone out there explain/define which is which?<br /><br />Thanks.
