OOohh...you have an Acadia? You mean one of the old make-and-break
engines? That must be fun.

Yeah, it is! It's a 10 HP. They were made in Bridgewater, about 13
miles from me and I was in the plant in the early 70s when they were
still making them. They had a contract from the government to make
them for government wharves -- wharves built in many small fishing
villages, owned and maintained by the feds for the local fishing
fleets. Those 10HP Acadias came equipped with a sprocket and a
chain-driven winch to haul boats out on a skidway. That ended in
the
70s and many of the engines were vandalized or stolen.

Mine is the same size but isn't one of those. It's equipped with a
flat-belt pulley. Shortly before the plant was closed, the manager
gave me a photocopy of the "manual" for my engine. I've put it on
line:

Those old beasties are pretty cool to watch running. They had lots
of
folks bring their running engines to the old Vista, CA Gas and Steam
Engine Museum during the Fair days. Ditto the Pottsville shindigs
in
Merlin, OR up here. Everyone called them "hit & miss" engines. I
got
to help a few guys get theirs running (mostly grunt work, but fun),
but never tore one down. The centrifugal governor grounded the
spark
and kept the exhaust valve open during overrev. Simple yet
effective.

I timed a large one idling at a show. It would fire two or three
times, then coast for 45 seconds.


Yeah, with no drag on it. The big one in Vista had a 6" diameter
exhaust pipe which would blow smoke rings when it was running. I think
it was a Chicago Pneumatic 70hp with about a 7' diameter 12" thick
flywheel. It was either that or an Ideal type K. They evidently had an
influx of new Morse engines since I left.

When they had tractor shows, they'd run the old steam traction engines
with belts to do hay baling, log milling, and all sorts of things.
The locomotive-looking types would sure put off the heat! The
blacksmiths would fire up the coal and make tools and trinkets for
sale, etc. It was an all-day fun affair.

She's a big 'un. What's that screech, just before the slight whistle
while it runs? Sounds like an oil cup (or three) is empty somewhere.
