B&S 20hp twin problems

[JHC]

My 20hp Twin (461707, Type 0145) is acting up. It will only run with the choke on. As soon as I push the choke off, it dies.

I plan to rebuild the carb but am I missing something?

Thanks in advance of any replies.

Sounds like you just need to take it apart and clean it real good and try that before you rebuild it. More than likely the jet is partially clogged with dirt.

If you were sitting in the seat, On the left side of the carb. on the bottom of the bowl there is a good size hex head screw. Remove this screw and up inside is the main jet. If you have a compressor spray some choke cleaner through it and blow it out good, You can reach up in with a allen wrench and remove it for cleaning also. Once clean put the plug back in and give it a try. Oh some models have a fuel cut-off solenoid in place of the screw if yours does just remove it and do the same as above.
