I want to adjust the sensor air gap in my Volvo-Penta I/O. The Clymer's
manual says use a non-metallic feeler gauge (note: non-metallic, not
non-magnetic). I've checked all around and cannot find one. A google
search of non-metallic feeler gauge bring up references to it's use for
some autos, but no sources. Snap-Ons online catalog does not list one.

It's not a non-metallic feeler gauge you need, it's a non-MAGNETIC feeler
gauge (i.e., brass). A set of brass feeler gauges is put out as a
common service tool for exactly the task you're trying to accomplish, see
