Tonight it was time to rebuild the carb for Goldie. I'm using a standard C100 carb, which is a 13mm Keihin. I have a small box of old crusty carbs, so I grabbed one and started. First step was to take it apart and then clean all the gubbins in the carb dip.
This is a downdraft carb, with the throttle barrel sitting 90-degrees to the air flow:
It also has a built in petcock on top of the float bowl side:
Choke plate lever in on the right, operating a simple flate plate inside the intake throat:
The two main parts of the carb pulled apart. Air flow on the left, float bowl on the right:
The float side pulled apart, witht he little brass float:
Petcock pulled apart:
All the different little adjustment screws and the throttle valve with needle:
All finished. Thanks to the rebuild kit I got in from Thailand, I was able to replace all the gaskets and o-rings, along with a new main jet and new idle and a/f screws:

Great post. Are you sure the carb is a 13mm Keihin? I have seen other places identify it as 16mm. I am working on an old C100 right now, and the carb seems pretty shot, won't stop leaking gas. I would like to get a replacement, but most of the stuff online appears to be bigger bore and meant for the (relatively) newer C70s.
Would like to know where did you get a rebuild kit with all of the seals.
Thank You
