Troy Bilt Tb32Ec Wont Start. Springassist™ technology for easier pull starts. If the recoil starter assembly is defective, the engine won't start.

I've take apart the carb and cleaned it. This did not fix the issue. You might try dumping all the old gas out and with no throttle, full choke, with spark plug in, spin it over half dozen times to clear the fuel from the carb.
