Re: 2100 no power in the cut
« on: July 11, 2014, 02:26:53 pm »
The 2100 has a governed carb and must be tuning while under load.  So they might sound fine when rev'ed up with no load because all the fuel is coming from the limiter circuit.  Once in the cut and pulled below the limiter circuit RPM it could be running very lean. 

As well, the limiter circuit could be the problem.  Their spring check valve often gets weak and dumps extra fuel at too low of RPM.  The limiter circuit can be disabled by placing an aluminum disk (cut from pop can) under the check valve (the brass screw plug on the right side of the carb next to the choke shaft).

Also it could be a fuel delivery problem.  Plugged fuel filter, crracked fuel line or the carb could need a rebuild.

Good luck!
