About this kit

The FS85 is the trimmer landscapers kept for fifteen years, and many of them are on their second or third carburetor. Our replacement follows the C1Q-S186 pattern that Stihl used across the range, so the same carb bolts onto hedge trimmers, pole pruners, edgers and the SP80/85 harvesters as well.

Both kits include two gaskets, two grommets, two feet of tubing, two fuel filters, two primer bulbs, an air cleaner, a pre-filter and a plug. The second option lists a few more HS and HL models; the carburetor body is the same, so choose on price.

  • Fits FS80, FS85, FS74, FS76 and FS85RX
