Your hedge trimmer uses an engine of a different design to the norm that claims better scavenging or clearing the cylinder of exhaust gas before the next load of air-fuel mix enters the cylinder resulting in lower emissions and increased fuel efficiency.
The 2-mix engine clears the cylinder by pumping fresh air through part of the induction system and up through the transfer ports followed by the air-fuel mixture.

Spitting through the carb is almost unheard of with a 2-stroke engine and in order for that to happen there must be still-burning gas present in the combustion chamber when the transfer ports open and at a higher pressure than in the crankcase.
I guess it is possible a massive compression leak past broken piston rings might cause this but otherwise it could only happen if the port timing was off or the exhaust is causing too much back pressure.

The only way for the port timing to be off is for the piston and cylinder to be mismatched.

Check the tension of the deck belt. See owners manual


If the engine has oil leaks from the valve covers or crank seals be sure the belt is dry. If oil.

If belt has burnished it may need replaced.

Depends in the machine. The Troy Bilt tillers rotate tines in the same direction as the drive wheels.

A few manufacturers chose to "counter rotate" and the tines rotate in the opposite direction of the drive wheels.

If it produces black smoke when sputtering, then too much fuel and likely a carburetor float inlet needle issue.

Does it start back up or does it die and have to cool off for an hour or so? If it it has too cool down then it could be the ignition module. Check for spark.

It has an OHV engine that requires periodic valve adjustment every 100hqrs or so. Check engine maintenance schedule.

Another component to check is the anti afterfire solenoid. If bbn it's not working properly it will cut off fuel.

If you're running with a mix of stale fuel you need to completely drain all the fuel, including the carburetor bowl and refill with fresh fuel.

I would suspect the recoil start cord has some how wound backwards. Simple 2 cycle ported engines will run opposite normal direction, just not as well.

engine rpm would be the only other thing. or you have the belt routed incorrectly. are the blades upside down? I see that on an almost daily basis with customer units.

Two suggestions. One, Are you using the correct oil? Two, have you tried flushing and cleaning the pump, feed lines and the reservoir tank. Old oil can go bad and turns to a thick black toothpaste like substance. Dispose of the waste oil and mess safely. That way you don't get into trouble for it.
