Stihl repair manuals where can I find them

SOURCE: replace start cord on stihl fs 36

hello sir, i'm guessing the rope is broken , first you'll need a c-clamp large enough to clamp the spooler, needle-nose pliers,a small tipped screwdriver and a new length of rope.the safest way is to remove the rewind assembly cover leaving the spooler in place in its housing. try to remove the old rope with neddle nose pliers ans small tipped screwdriver.next hand spin the spooler to achieve spring tension until stops back off enough to line holes up, place c-clamp to hold it in place,now try to fish the new rope into the hole in the knot recess,trying to guide it to the exit hole in the cover, ( it's easier to feed the rope if you singe the end of the rope with a bic lighter and form to a point )and with a small knot at the other end,pull the rope all the way until you can seat the knot into the knot recess.next tie a loop knot into the other end of the rope,so the end wont be recoiled all the way into the housing.with tesion on the rope gently remove the c-clamp and let the rope be drawed in.if it draws all the way to the loop knot, check to see if the spooler is full if so,( not too full where rope is binding ) pull the rope about a foot and re clamp the spooler and install the pull handle, if rope is too long you may have to cut to length. if it doesn't draw all the way to the loop knot and the spooler is not full than you may need to add anoyher revolution to the spring tension in the same fashion as described above.there are eisier ways but that evolves removal of the spooler and repacking the reciol spring.( not for the novice ). hope this helps,MrFixIt,thank you. `

SOURCE: My Stihl FS 85 Weed Eater gets no fire to the spark plug

older models have a pick up and condenser for spark. newer models have pick up and ignition module. the pick up rust the condensers and modules go bad. first take apart to expose flywheel then ck for rust on flywheel at pick up if rusty clean set pick up clearance to that of a matchbook or ten thousands of a inch.if still no spark change condenser or module.

SOURCE: stihl FS 80 carburetor settings for high and low screws

Hi F Del
Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
If you have aready tried to adjust them then the adjustments below should get it running for you for final adjustment when warm.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.

SOURCE: hi, have a stihl fs 85, runs fine for 10 minutes, then just cuts out. tried cleaning carb, muffler.

Two things spring to mind, fuel tank breather, to rule this out slacken off the filler cap when the machine starts to die, if it picks up again change the tank breather, or the ignition coil is breaking down when hot, this would require a replacment unit.
