Removed and cleaned carburetor

As I mentioned, this is my first bike with a hidden carb. The carburetor was in pretty good shape, in desperate need of new fuel line and a cleaning.  At some point it had overflowed, evidenced by the buildup of varnish next to the oil pump.  The throttle valve was stuck, but a tiny spritz of WD40 freed it up instantly.
  
Notice the varnish towards the bottom, on the oil pump
I took this picture as a reference for the oil pump cable adjustment
The throttle cap and enricher valve came off with ease
Jet and jet emulsifier removed
Its good to have a picture of the jet number
Mikuni VM17-18
A nice, simple carburetor is a thing of beauty
I believe the replacement fuel line is 7/32, and the OD works well with the grommet in the case
