Stihl fs80 (av?) Replace original carb

The viewer from my other video asked about the non standard carb on my trimmers. Here is how I replaced the original TK carb.
This works with similar models also from the 70's/early80's from other brands (several identical motors\TK carb) such as Echo SRM-200da, Shindaiwa T25, Stihl fs61-65, FS51, FS81/86, (old) Green Machine, Kawasaki, Toro TC3000, among others.
This will also make fs6*, fs56, or any others with 1 fuel hose so you can run it upside down now to trim sidewalk or if u have a saw blade cut branches..


Other tidbits:
-the orange Echo gas cap fits these old Stihls(fs 80, 60-65).
-there is an adapter so the tap feed trimmer head available - ebay item #143531335294.
-I have a workaround if your fuel tank grommet leaks.    • Original FS80 Fuel Tank grommet work ...
