Since Monday was a holiday, the parts and materials ordering has been delayed.

These connection points are hoses. You can really feel the age in this carburetor.
Since it’s exposed to the elements, deterioration might be faster, I suppose.

There was no significant rust or anything; it was in good condition.

I didn’t want to get too deep into it, but I went ahead and set it to four for now.

Dirt has accumulated on the inside as well.

Carburetor small parts are supplied in only the bare minimum from a product liability standpoint. This fiber packing near the shaft isn’t supplied either, so I’m always torn between reusing it, finding a substitute, or something else.

The more work I do, the more I wonder if it’s really just a matter of taking it apart, cleaning it, and reassembling it for an overhaul.

The starter valve has collapsed. This is the first time I’ve seen it go this far.

p1630019
Most are center pin type, but back in the day there were plain ones too. Some ran poorly depending on how they were adjusted.

p1630022
One acceleration pump rod was bent. Since the part isn’t available, I straightened it and reused it. The seals around this rod area aren’t supplied either.

I clean up what I can on my own.

It’s already clean, but let’s clean it up as much as we can.

It’s cleaner than new.

The parts won’t arrive for a little while. Since I’m making a carburetor box, I can put them in here so they won’t be in the way, and there’s no risk of parts going missing or getting mixed up.

Bosch

For boxes used in organizing and tidying, I think it’s good to choose something that lasts a long time and looks nice even when sitting around.
I was able to handle it with a 3 mm inner diameter Honda bulk item.
