Many of us (like myself) may have lived a previous life hot rodding cars where tachometers are easy. In the small engine world, tachs seem to be a less common, but they are more necessary on a governed engine.
So...especially when using a snow blower where you need every rpm available, it is worth checking what you got. I decided to use the "Tiny Tach" ( http://www.tinytach.com/tinytach/index.php ) which is adjustable to different small engine firing patterns. Very easy to install, just one wire to wrap any spark plug wire with, and one ground. I have bought two; I adjusted my 1861 with one (was set 600 rpm low), then installed them permanently on the dash of both my Supers, either of which could be called on for snow blower duty. Incidentally, the Magnum in the 1872 was low as well by about 300 rpm.
I am still waiting for the correct police to come after me for mounting a non-stock accessory to the dash...
Someday I will try posting pics...
