Is your welder speeding up when you strike an arc? It sounded like it
was loading down and running slow. It should speed up to 1500-1800 rpm
the moment you strike an arc and drop back down to 700 rpm when you
drop the arc.
It does not do it, for some reason.

Your governor is not working or is adjusted very poorly. Take a picture
of it and I can tell you how to repair/adjust it.

John, here's a few pictures.

Aha! A third method of speed control, other than those that Gunner
and I suggested. I guess it's a mechanical adjustment you'll need to
make, Ig. As the governor slows down, it should open the throttle
slightly.

Degrease that puppy and git-r-done, boy.

MOST welders use both a mechanical governor and a "demand throttle"
The demand throttle tells the engine "load coming" and kicks it up to
the load RPM, which is then controlled by the governor. At low loads,
the RPM is maintained with minimal throttle opening, while under heavy
load the throttle may need to be wide open to maintain the 1500 RPM
called for by the generator.
When no load is being drawn (no arc struck) it returns to idle, which
may be 700 RPM or so. Very few ru with ONLY a demand governor, and
only the cheapies run with only the speed governor (running fast all
the time on the mechanical governor only)

Absolutely NOT! Use something a bit milder, like 409, Simple Green,
Purple degreaser, etc. and hose it off.

Or use a brush and paint thinner.

Or pressure wash it.

Yeah, after Steve pointed out the solenoid, I looked for wires and saw
them in the pics after all. I sit corrected.

Evidently the governor is for overspeeding, the solenoid for
welding-loaded idle.

The governor and the solenoid work in conjunction with each other. The
governor controls the rpm only when the solenoid is pulled in. With the
solenoid disengaged the engine rpm is set by an idle adjustment. What
you may find if the solenoid is not working some operator cranked up the
idle adjustment so the engine runs fast with no governor control. The
first thing is to try and see why the unit is running fast after you
start it up. The solenoid should not be pulled in. The governor will
be positioned to open up the throttle usually working against a
mechanical spring to close the throttle but the arm from the solenoid
disengages the linkage from the governor to the throttle and a spring
pulls the throttle closed to the point where a stop rests against the
idle adjustment screw. Once the solenoid pulls in the governor
controls the throttle and the adjustment for the governor sets the rpm.
When the system is set right it is a joy to here the thing power up
when you strike an arc or pull the trigger on a grinder.

No, the governor is for regulating load speed., and the solenoid for
idling with no load.

The solenoid doesn't pop the throttle up under load? That seems
backwards. A/C solenoids bump the throttle up for the load the
compressor puts on an auto engine. I thought these would be the same.

In most cases with welders and generators the solenoid is energized
when the load is connected, effectively connecting the throttle to the
governor. When disengaged the throttle lonkage disconnects from the
governor, returning to idle. Not sure if the SA-200 works that way or
not.
