Husqvarna yth150 engine surges after warmed up

T.R.K. · Mar 23, 2021

If feathering in the choke part way helps the surging, then its not getting fuel somewhere. Most likely a gunked up carburetor, but it could
be also a plugged fuel filter, collapsed fuel line or trash in the pickup tube in the tank.

If you can adjust the carb, open up the high speed needle a little. TRK bought up some good points, I would try some Sea Foam before I spent
any money on parts. The high speed jet may have some varnish in it, and Sea Foam will wash it out.

Another thing: The vent in the fuel cap may be stopped up.
