dieselpilot said:BTW, I have a set of B&S snap gages I can't get to work well at all. It seems when I tighten the thimble before pulling it from the bore it retracts the points a touch and is sloppy in the bore.
I've also had that problem - try putting it in slightly skew so that it is "oversize" - lightly tighten and then tip it straight - this will force it back to true - tighten further - remove and measure.
