I picked up a wisconsin 2 cylinder engine today its a propane engine, how
do you connect the propane. the motor is a Wisconsin THD engine looks real
nice, not sure what I would use it for but the price was right.
In the top photo, that big hose that comes off the right side of the
carb and heads up is the Propane inlet - but it has to be after the
primary vaporizer/regulator at about 2 PSI max. You can NOT just
connect it straight to a barbecue cylinder without a primary
regulator.
(You might be able to get enough gaseous propane flow out of a
barbecue cylinder to run the engine without the cylinder icing up and
the pressure dropping off to nothing... But I wouldn't count on it.
To run this flat-out, you need a forklift style tank with a liquid
output fitting.)
The vaporizer is a large cylinder about the size of a quart paint
can, and it will have a separate set of 3/8" or 1/2" NPT water hose
fittings - in a car, you plumb it into the heater hoses and use waste
heat to vaporize the liquid propane feed from a "liquid" port on the
fuel tank.
If you want to test the engine for signs of life without spending
for an LPG vaporizer, do you have utility-fed natural gas at your
house? That's roughly 8" WC pressure, should feed right into the big
hose... ;-)
I saw a Corvair conversion where they ran the motor oil cooler lines
to heat the vaporizer, worked just dandy. Any waste heat source will
work, Automatic Transmission cooler lines or hydraulic system.
As to what you can do with the engine, it all depends on what kind
of governor system it has on it. If it doesn't have the fine-control
type flyball governor built in (which it looks like it might) forget
using it as a generator plant. You can get external governor systems
that will hold 1800/3600 RPM on the dot, but not for cheap unless you
scrounge it.
I can't tell, it looks like it has either the 6:1 reduction gearbox
or the end bell from a generator (that was removed) on the back end.
Though the engine looks suspiciously like Onan Green... Best use is
to find a good generator with a blown engine and bolt 'em together.
