Hello Toni,
If your problem started after the service, check to see if the heat shield (aluminium plate) and plastic insulator are in place between the engine and the carby. These prevent heat transfer from engine to carby and assist hot restarting.

The manual for your machine is available on the TORO website.

There are also other threads on this site for suzuki engines.
cheers from Mark
