About this part

ECHO's PB-403 and PB-413 backpacks are old favourites with landscapers, and the C1M-K77 carb feeds them along with the PB-460, PB-600 and PB-620 series. Our kit includes the filter, lines, primer bulbs, plug and gaskets.

Not sure which Zama number your blower wears? Send us a photo of the carb before ordering and we'll match it. We've been matching carbs for more than ten years.
