The specs are INTAKE .10-.15 mm (.0039-.0059 in ) and EXAUST .15-.20 mm (.0059-.0079 in ). Hope this helps. These are from the factory service manual. Go to this link it is the complete factory service manual.

Thanks! Will give it a try!!! You've helped more than you know. We googled all morning for the specs before joining this forum. I can say I'll definitely save this forum site in my favorites.
Thanks again.
