Carburetion
- This page has an excellent explanation of how carburetors work.
Cleaning
Rebuilding
- Serius Consolidated Inc sells carburetor rebuild kits, which seem to include:
- float bowl seal
- top cap seal
- float needle
- o-rings
- main needle and clip
- main jet
- pilot screw.
- Partsnmore sells somewhat less comprehensive rebuild kits for vintage carburetors.
- float bowl seal
- five o-rings
- top-cap fiber seal
- float needle
- Compare the Sirius kit to the Partsnmore kit for the 1978 CB750.
Petcock
Sealing
- This thread discusses how to seal a weeping British petcock.
- Jomar Gimme the Green Stuff is a soft-setting sealant which should prevent gasoline seepage.
Connectors
Quick Disconnects
It's often nice to have a quick disconnect on your fuel line to make tank removal much easier. There are several options, and most of them are probably bad.
Plastic
MotionPro sells plastic-bodied quick disonnects. Chances are, they're the same as the ones on BMWs that are supplied by CPC - Colder Products Company. The problem is that there are many, many instances of the plastic bodies breaking on BMWs, stranding and possibly igniting the rider!
MCMaster-Carr sells various plastic bodies that are likely comparable to the MotionPro and CPC connectors.
Metal
CPC also makes a chromed brass series (it still uses plastic internals). The problem is, it's still rated to the same 180°F temperature limit!
The other problem is that all of these options are quite expensive. For example, a 1/4" complete connector (male and female sides) chromed brass version would cost $37.49, plus shipping, from quickcouplings.net. In my case, I need two sets of connectors since I have two fuel taps. That's $74.98 for a set of connectors that still might fail being so close to a hot engine and exhaust.
