Engine & Torque Specifications 


What's the correct spark plug gap?  How tight should that nut be?  What's the firing order again?  Or are you simply looking for that bit of technical information that you may be lacking?  It's probably listed here and we suggest that you use your browser's "find" feature.  If you've got something to add; let us know.  This IS the "mother of all specifications" list!!!
