I've got a feeling the governed full speed RPM of the 6 HP Tecumseh
"Snow King" engine on my 1964 Ariens Sno-Thro has been decreasing over
the years, as the "Widow Maker"* doesn't seem to be launching snow as
far as I remember it could a while back, and nothing seems obstructed or
noticably worn.

I've got a spark induction tach, but when I looked in the original
manuals this morning, there's no mention of what the full speed RPMs
should be set to.

The governor spring has probably taken a set over the years, probably
because of my habit of shutting it down by leaving the engine running at
full speed and closing the fuel petcock, which leaves the spring
stretched a bit all the time.

Thanks guys and Happy New Year,

Jeff

* So named because it predates safety features. The front halves of the
auger ends are exposed and there's no dead man system, other than the
gas tank running dry.
