clean thecarb. there are usaualy two circuits. 1 is slow spped circuit and high.
if it will not help check compresion readings.
when compression is low motor wil die on slow speed setings( idle)

Is your model MFS30B? If so, it is EFI, and there isn't any carb. If you get the diag software, you can connect a laptop, and check injectors, etc.

No carb on an EFI motor.

If you change the TPS, you must reset the TPS initial setting.
