The old welder/generator I picked up today doesn't look too bad if you
sort of squint at it and ignore the gas engine, which is missing a lot of
parts. I may get lucky and find a parts source, but right now I'm
wondering if it might be possible to just go find another motor with
similar specs and just patch it in.

Anyone done this?

Make sure the generator is OK before putting a lot of effort into the motor.

Note what others have said about the usefulness of a non DC welder and
especially one with limited duty cycle. IMHO this is/was a pretty marginal
unit even when it was new. it is basically a small AC only buzz box with
the added disadvantage of needing expensive gasoline and maintenance.

IMHO, Good tradesmen don't waste time on or with poor tools, they just make
it harder to do a good job, and are much less pleasurable to use.

It may have been a marginal unit, but it is certainly an AC/DC welder. Lincoln
did make AC only models, perhaps you are remembering one of those. There are
some OK pics of a very very similar welder in much better shape than mine on a
current ebay auction (150140941115), here are pics of the gas engine on it:

South Seattle Community College has one of these welders, and Ernie says it has
exceptionally smooth DC.

If I can get it running correctly and completely functional for under about $400
total, then I'm going to do it. If not, then I'm going to part it out and keep
the leads. If it doesn't weld well then I will certainly let it go. I've been
pricing gas-powered welders for awhile, seems like $800 and up is the going rate
around my neck of the woods for clean functional units.

Well, you've got a Briggs & Straton engine. Parts should be available
for it. From the picture the air cleaner is still on it which probably
means that the carb is still there and it probably needs cleaning and
maybe a new float valve.

The exhaust is a piece of water pipe and will be noisy but you can
always weld a muffler on that.

Unless there is something else missing that doesn't show in the
picture I'd say you could get it running in a day or so.

Take the spark plug out and short the threads to the head and give the
rope a pull. If you see a spark that part is working. If you have
spark squirt a little gas in the plug hole, screw the plug back in and
give her a pull. I'll bet she'll pop and it does that it'll run with a
little more fooling with it.

I'd try to find a guy that repairs lawn mowers and have a chat with
him. Most of these guys know something about B&S engines. If you can
find one that is semi-retired and bring over a six pack I'll bet you
can get it fixed.

Once you get the engine running check, and maybe replace the brushes
in the generator, and if necessary bake the windings and repaint them
and I'd reckon you'll have a pretty good little welder.

Lastly, if you are having trouble finding parts ping "Gunner" either
here or on rec. metalworking. Apparently he has most of the parts in
California stored in Bakersfield and knows where all the rest of the
parts in California are hidden.
