MarvelSchebler Carb diagram

Think I figured out how to add a picture. Don't know about the size though. Hope this helps you out INcase. NorminN.B.

This diagram was posted under my handle in parts & pieces photo gallery. You need to shut the fuel off at the sediment bowl when not using it. Also try a needle seat kit in another brand maybe? I've had trouble sometimes with ones from Zenith/Marvel Schebler kits not fitting right but not often. Usually threads are messed up from someone tightening it too tight or crossing threads from installing a poor fitting generic one. Sounds like the threads on seat or needle is still leaking. Thread repairs in casting and refacing the seat thread surface may be needed. Also shake the float to make sure it isn't laden with fuel inside. You can also hold the float with a pair of pliers in a pan of hot water (not boiling) and see bubbles spewing from it if it has a leak. After draining fuel you can solder leaks shut on them but new floats are available reasonably. The TSX floats are also bad about collapsing some and if it's like that replace it with a new one to get back the buoyancy needed to keep the needle shut.
