Tractor starts but dose not keep running

Thanks

Typically, the ballast resistor is only in the circuit during "Run". In "Start" position, the coil gets full voltage while cranking. If it starts then dies, it may well be a bad resistor.

Ok. Will check that. Thanks

A bad (open) ballast resistor it will have spark while cranking only. No spark in run. So if it cranks up and continues running in run position even a few seconds, the ballast is OK. If it runs while cranking, dies in run I would suspect ballast.

There is a fuel filter in the banjo fitting where the line attaches to the card. Other common carb problem is bad accelerator pump. The S650 is not gravity fed & has a fuel pump. the fuel system is not pressure regulated
