Stihl chainsaw won’t start

Stihl chainsaw won’t start. A chain saw’s two-stroke engine can struggle to start as a result of many mechanical failures.

These failures range widely in complexity and cost but all have one thing in common: no matter the issue that causes it to misfire.

The cause is a part of the ignition and fuel system. Partially due to their design, these parts must be bypassed or replaced in order for your chain saw to function properly.

Stihl chainsaw won’t start. Dirty fuel tanks, fuel filters, hoses, and the carburetor restrict the flow of gas. Inspect all the petrol system parts before moving into the engine as they are trouble makers.

Problems with the fuel intake

The spark plug is perhaps the most overlooked part of an engine that actually serves a purpose.

It converts the gasoline, which is coming up from the fuel tank and being sucked in through the carburetor, into energy.

Energy ignites inside the cylinder at precisely the right time when it’s needed to start an engine running.

The timing on this energy burst is everything, so if something impedes its flow it will create a misfire and cause your vehicle not to move no matter how hard you hit the gas pedal.

Restricted flow can also be a sign of a more serious problem like dirty fuel or spark plugs that need replacement. internal engine problems.

Problems with the ignition spark

The ignition system in your Stihl engine powers a flywheel and when this flywheel spins, two magnets generate magnetic energy. When enough energy is created, the spark plug gets tripped.

This sends the spark up to the fuel mixture where it ignites and makes your motor fire out of control. If you inspect your ignition system at each point starting with the sparkplug and moving back to the flywheel and ignition module.

You will be able to prevent problems from causing serious consequences such as causing your engine to combust out of control by not allowing enough compressed air into the cylinder.

Compression issues

The function of the spark and fuel systems is to work together in order to get the fullest possible effect out of combustion, which is why having a high-quality overall design is so important.

It’s also important that they are properly maintained if your goal is a long life for all of these interconnected components working together.

Along with the engine shaft and cylinder, there is also the crankcase which relies on certain aspects of the compression process in order to keep everything effective like all other internal parts do.

However, whenever something goes wrong or an air leak or blockage occurs, for example, this can cause problems and affect how quickly or effectively compression may work within your engine allowing it to run but only for much less time than it could if it was uncompromised.

The carburetor may be clogged

Carburetors often get clogged for a variety of reasons. For example, if the gasoline left inside of the chainsaw is allowed to sit for too long, some of the fuel may evaporate leaving a more viscous substance behind.

This can eventually clog up a carburetor no matter how well one tries to clean it out with a carb cleaner.

Therefore, your best option as a homeowner is to either rebuild or replace your carburetor entirely which will require you to take your chainsaw in for professional maintenance.

Faulty Rewind Spring

Pulling and releasing the starter cord is supposed to allow the recoil starter to pull the cord back onto a pulley, which in turn should cause rotation of the engine.

If there is a problem with the recoil starter or spring you may have difficulty starting your chainsaw.

Difficulty or inability to start your chainsaw will probably signal an issue with either the starter itself or its spring, both of which may be replaced individually.

Defective ignition coildefective ignition coil

The ignition coil sends voltage to the spark plug while the engine is running. If the ignition coil is defective, the engine may not start.

Before replacing the ignition coil, make sure that the spark plug is working efficiently or if it needs to be replaced as well.

Test your ignition coils using an ignition coil tester and replace any which are deemed faulty.

Recoil starter assembly not working

The recoil starter engages the crankshaft to turn over the engine. If it is defective, the engine won’t turn over and the chainsaw won’t start.

Remove the starter and inspect it to see if it is functioning properly. When you pull the rope, tabs on the pulley should engage with a hub on the engine, causing it to rotate.

The tabs should retract when you release the rope and when rewinding back on itself, so make sure that everything functions as expected if not, replace the assembly.

Recoil starter pulley broken

The recoil starter pulley retracts the starter rope. When the rope isn’t in use, it should be retracted using the recoil starter pulley.

If the pulley is broken or damaged, it can break and not retract the starter rope properly. As a result, you’ll open the engine compartment to replace it.
