>I got the SA 200 running today.
Just couldn't stand it. SWMBO was late with dinner because of a home
remodeling show on TV, so I went out and put the leads on and fired it up.
Ran four 7018 rods, and it runs great. Used the plug for the Makita
stringer brush to clean them up. Ran them at slightly different settings,
and had one that just curled up and popped right off by itself. I love
those.
Running rods at night has an unusual aspect. The inside lower part of my
NexGen lens is white, and gives quite a reflection and distraction.
I'll get the engine hiccups solved, but the powerplant is okay. It's so
nice when a plan comes together.

If it only runs with the choke on you probably need to clean the carb
again and maybe reset the float level.

Higher or lower? I pulled it again this afternoon and ran some pipe
cleaners through again and blew some more air through, and it was better.
There are still a couple of small brass orifices I could not get out. And
one that takes a very big screwdriver that I cannot find, but will look for.
I tend to think it's something else, because when you put it on automatic
idle, it doesn't drop down when you cease welding. Even though it would
probably die if it did attempt to idle at a lower speed. Like I said, I'll
get it figured out or fix it. I'll pull it again today and repeat. Hell, I
can pull it off in five minutes now and be looking at the float chamber.

You have some trash left in the carb somewhere, having to leave the choke on
is a common problem on these carbs. A passage becomes blocked and you need
to increase the vacuum to get enough fuel. This happens to my Continental
powered fork lift sometimes.
Take great care in removing and replacing the orifices, this is pretty much
the whole ball game with carbs, but it needs to be done. Make sure your
screwdrivers fit correctly. If you round the edges of a stuck orifice and
can no longer remove it, you can just about toss the carb. Also take care
not to over tighen them when you replace them, they will need to come out
again some day. I use "Brake Clean" spray or "Carb and Choke" spray to blown
out the passages, followed by compressed air, unless you have something
better.
NAPA has a gasket set for the carb, and a high quality fuel filter is good
insurance for the future.
Does the throttle linkage have a spring and vacuum chamber attached to it?

There's two arms that run forward, one, I believe to the governor, the other
to a blue box which is mounted in the upper position. Both located in the
fan shroud area.
How much would you guess a carb is for these?
