STIHL Genuine 1106 Series Carburettor Compression Washers (2) # 1106 121 8600

Genuine STIHL fibre expansion washers 
Note: two in each purchase.
These fit under the flared nuts that hold the Tilly or Zama Carburettors in place
On a lot of old saws they are missing, as over time people lose them when doing maintenance
Of course they are there for a reason and a good one as they help keep the Intake flange joints tight and sealed.
