Twin carbs, both need work to yield one good one.
While body pieces are out for refinishing, I wanted to get started on the carburetor rebuild. I bought a second complete use one online in case I need any parts, which I certainly will. Unfortunately, both have similar problems. I disassembled the original carb and found exactly what I expected: a lot of gummy gunk in the float bowl. The good news is that the floats are intact and fill valve appear to work. The bad news is that the throttle insert is stuck tight -and I mean TIGHT- in both units.
I had hoped for this to be a one-day project, but it'll take several at my pace. First I've got to strip all of the gunk out of the float bowl and jet insert. I've got some great chemicals that are helping with that. In fact they're soaking over night. Once I get them stripped and can see what I'm dealing with, I'll attach the problem of the stuck jets. None of the industrial lubricants have worked thus far, so the next step is some brute force. I have to be careful not to break the housing, but then again I've got a spare if I need it!
In the photos, the top one is the one I bought online, the bottom is from the bike itself. The purchased one has a rusted source value so I will wind up rebuilding the original rather than the new one. Though the original is dirtier, it's actually in better mechanical shape.
