Sounds like the idle may be too low and when you engage 4x4 it’s putting extra “load” on it. There should is an idle adjustment thunb screw on the carburator. Run the engine until it’s warm, then adjust the idle until your RPM’s read about 1000 to 1200. You can probably reach the screw without removing the side cover just be careful not to burn your hand on the engine. The idle screw itself won’t be hot. Make sure the transmission is in park and set the brake.
