SOURCE: stihl fs 45 ignition problem no spark

Disconnect the small spade terminal wires from the coil itself and test for spark. If you do not have spark replace coil. If you do have spark check those small wires for insulation damage and grounding. If wires are OK check kill switch.
NOTE: DO NOT START MACHINE with small wires unplugged! Only test for spark.

SOURCE: how do i set the carburetor on a Stihl FS-55

Over the past 8 years, the FS55 has had at least 5 different carburetors, and they have at least 3 different systems with different adjustments. Many of them do not have much of an adjustment and will not cure running problems. If you are experiencing poor running conditions, I would suggest some basic checks first. The spark arrestor screen is a big culprit on this model.

Basics to check:
1) Spark plug - brown or dark brown - OK
a) is it carbon or fuel fouled
b) is there spark

2) Muffler remove for inspection
a) exhaust screen clean or plugged
b) inspect cylinder wall/piston as the flywheel is slowly rotated
3) Check cylinder compression

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

SOURCE: Replacing trimmer line with blade for stihl fs 90r trimmer

If you bought the trimmer new there should be a rod about 6" long and 1/8" thick. Above the trimmer head below the trimmer gearbox there is a hole. You have to put the rod in that hole and turn the head until that locks it from turning.

From there you can screw the trimmer head off by hand, or a strap wrench if it's really tight. It may be left hand threads.

I am rebuilding a Stihl trimmer model FS 110 R carburetor and I need to know what gaskets to use and where they go


You will need to remove the carb and see who made it as most manufacturer buy there carbs. , ie: walboro, it will have a marking on it along with the carb number such as wt784. Then you can go to ebay or your local lawn mower shop and they should have the rebuild kit. It cost about 4 to 6 dollars. Just reassemble it the same as you take it apart. When you take the jets out be sure to count the turns and then you can put them back when you are done. In addition if you look real close, because the stamp are tiny you will see a L for low idle and H for high speed. Hope this helps.

I have a Stihl Weed eater will a FS 45 carburetor fit on an FS 90


NO. The FS90 is a 4mix engine and the carb has a (sump) on it which has a pulse pipe going to the bottom of the crank. The FS45 is a totally different carb configuration, and doesn't have the sump. FS90 carb is an C1Q-131A

The FS45 has several carbs that fit:-
C1Q-S97
C1Q-S71
C1Q-S66
C1Q-S58
C1Q-S44A
C1Q-S53A

I have a stihl fs 85 whipper sniper will start if i pour fuel in carby but doesnt seem to be sucking fuel into carby


Could be a dirty needle and seat, gummed up over time. Or an incorrect float or punctured float. Clean the carb and rebuild it wit a kit from your local dealer.

My Stihl FS85 runs good for about 20 seconds and then shuts completely off. I have replaced the Plug, cleaned out the fuel system and it still does the same thing. Could it be the coil?


Sounds like the main jet or the diaphrams in the carburetor are deteriorated. Remove carb and soak in a good carburetor dip style cleaner and rebuild with a new kit. Also replace the fuel line and filter and use a fresh gas mix.

ZAMA CARBURETOR REBUILD


Unless you really know what you're doing i wouldn't advice it be carried out by a novice. Carbs contain small one way valves that can get damaged. Avoid using airlines to clean and blow out carbs as these can damage the valves. Diaohrams, gaskets and needles are pretty straight forward tho.

Need repair Manuel for Stihl br-550 blower


A shop like www.arcolawn.com can get you Stihl tools and parts.
It sounds like your carburetor is not meetering the fuel properly. A rebuild may work but the carburetors on many machines have fropped in half in the past 2 years.

You may have a bad seal on the crank shaft or an air leak somewhere. If you take it to a dealer most shops charge less than an hour time to perform a full check on the machine and you can do the work.

Good luck

I need to rebuild the carburetor on a Stihl Model 025 chainsaw. An exploded view diagram would help.


I don't have a diagram or the part numbers to the minor and major repair kits, but a Stihl dealer should be able to help. Tell him you need a kit for a ZAMA C1Q type carb. The exploded view should be with the kit.

Instruction on how to rebuild Stihl FS85 carburetor


The FS 85 was produced in HUGE quantities over a number of years. Several different carbs were used during production and Stihl has several proprietary carbs in use. You will need a Rebuild Kit (NOT just a Diaphragm Kit) for this particular carb. On the carb body you should see a Series and a Model identification.
Example: If this is a ZAMA carburetor, the C1U-S66 might have been used on your trimmer.
Get that info off the carb body and ...
For ZAMA carb lookups click HERE.
For WALBRO carbs click HERE.

Hope this helps.
