I've got 3 410/4111sst. 1 with about 6 months use, 1 with 12 mos, and 1 with 15 years constant. Parting out the 15, selling the 6 mos, keeping the 12 mos. Good gas tank. Have an extra NOS stand that bolts to engine. Just put a husky bump feed on with 095, seems to work really good ($26 at Lowes). Do you still need amything?Restoring an fs80? I have an fs80 that sees quite a bit of use on 4 acres. Bought it new 20 years ago. Only things replaced has been the gas cap, spark plug, air filter. Wore out 3 stihl bump feed heads. The stihl automatic feed head sucks. Switched to a speed feed head a couple years ago. +1 on the speed feed head
