Mark, I can't stress enough the need to have a feeler gauge calibrated primarily in metric units. The SAE ones have a conversion lasered on them but you loose the precision needed to zero in on the exact clearance. Spend the $14.23 at mytoolstore.com. I did way back in August of '03. I tried all the local places that sell gauges and no one had one. No one. Another thing you might buy (to help spread out the shipping cost) is a brass feeler gauge. You need one if you ever adjust your ignition pick up (Hall Effect). That gap is 1mm ±.02mm.
