Folks,

Thank you for the warm welcome - you are amazing :)
An important first question: What is the right forum to ask for "BASIC STUFF"?
I bought a couple of books (still going through those) and read a lot online about OHV engines and the drive train.
My biggest problem when I read through the forums though is that there is a lot of "jargon" that everyone seems to understand but means nothing to me.
Here's an example:
When someone says "600# valve springs" do they mean "max valve lift is 0.600 in or is that "open pressure of 600 lbs"?
That kind of noob questions.
