How old is it? Model? Can you move the auger single stage or augers 2 stage by hand when in neutral. Could be a ice jamb. or bad bearing. Do this with the unit NOT running. If it's a 2 stage take a 2X4 and insert in the chute
and try to wiggle or move the impeller. Bent impeller/auger? Maybe. check them visually.
Hope this helps.
There could be several different things to cause this, if it sounds like it is running wide open the first thing I would check if the butterfly on the carb, I have seen many cases where these come loose and lodge open in the intake. Please let me know if this is the case. Thank you. If you need further help, I’m available over the phone at https://www.6ya.com/expert/steve_f5a6ca85b5d1ffc9
points? unhook the coil and see if it has spark then. if it does there is a short in wiring to frame somewhere. is there resistance on the pull rope? it is possible it may have broken a connecting rod.
Remove spark plug and try to pull. There could be water on top of cylinder. Would replace rope before you beeak as it will be easier to see how it is wound etc. There should be many videos online showing you how.
You may have motor internal problems with governor control. Moving governor arm from engine and see if it operates freely if not try pecking on shaft that does into engine and see if that might free up.
When you installed the new carb did you adjust it for your engine? Idle control, idle mixture, fast misture? Running only with choke indicates that engine is not getting enough gas routinely via the main jet.
I show how to do the annual maintenance on this push mower. This includes changing Oil, Spark Plug & Air Filter on a Troy-Bilt TB110 push mower with a Briggs & Stratton 550EX engine.
