Here we have a Genuine STIHL Carburettor that fits many of the FS models

as we as the HT75 Pole Saw. I believe that this one is the same as the 4170 120 0628 Carby too. Meaning you can use one or the other.

A clean and fully functioning Carburettor is paramount to good engine performance.

Please check the parts list or IPL for your model if you are unsure if this one if right for you.

You can do no better than Genuine STIHL Spare Parts.

Here if you need one anyways...
