Q: My chainsaw won’t start, and I’m not sure what’s wrong with it. What’s the issue, and how can I fix it?

A : A chainsaw is a great tool to clean up fallen trees , trim undesirable branch , and cut back firewood . These tools can be stubborn when starting up , especially older exemplar with wear and tear . There are a few dissimilar reasons why a chainsaw wo n’t start , depending on whether it ’s a gas or an electric chainsaw .

Before beginning an probe or trouble-shoot the issue , though , always put prophylactic first and function under the premise that the chain saw could bulge at any time . Keep the saw facing aside from citizenry , vehicles , and structures and head off wearing baggy clothing .

Replace the spark plug.

If your chain saw has a defective spark hoopla , it can not create an electrical current to ignite the system . dispatch the electric discharge plug and scrutinize if it is ill-gotten , crack , erode , or damaged . There may also be a operose carbon buildup or a burned - up electrode .

If the discharge jade has one or more of these issues , replace it with a new one . If the twinkle plug seem okay visually , but you have n’t changed it in a few seasons , replace it anyway .

Clean the carburetor.

A chainsaw ’s carburettor mix in air and fuel to set off the interior combustion engine . If fuel has been left in the engine for too long , it can become sticky and clog the carburettor , preventing it from starting . If the clog is minor , sporting out the carburetor . To unclog a carburetor , drain the fuel , spray the carburetor with a specialized cleaning solution , and wipe it clean .

If cleaning the carburetor doesn’t work, replace it.

If the carburetor is too clogged up to be soundly cleaned ( or if echo cleanings do n’t get all the buildup out ) , it may want replacing . It could be damaged or old and no longer function .

To test the carburettor , remove the air filter , swarm a teaspoonful of fuel into it , and pull the starter rope . If the engine starts momentarily and then dies , the carburetor is likely why the chainsaw wo n’t get down . Toreplace the carburetor , buy one that is compatible with the chain saw , then follow the producer ’s instructions to swop them out .

Test the ignition coil.

The ignition whorl is the machine that sends voltage to the spark plug , creating a spark that ignite the fuel and turns on the chainsaw . If the railway locomotive is not turn on , then the whorl may have become bad , which can happen over time with repeat use . Once you ’ve confirm that the spark plug is not the topic , purchase an lighting coil tester and follow the manufacturer ’s instructions . If aspark does not occurduring the testing process , it is likely that the inflammation coil is faulty and needs to be supervene upon .

Check the recoil starter.

A recoil starter allows the hustler to pull up on the starter rope and lock the internal start mechanisms to work on the chain saw ’s locomotive . If the kick appetizer is defective or assembled improperly , then the engine can not start .

To test whether the recoil newcomer assembly is faulty , remove it from the chainsaw to see what ’s happen . The pulley system of rules may be stick and call for to be place back into its proper stance . If you try this and the chainsaw still wo n’t start , the recoil appetizer may need substitute .

Replace the rewind spring.

The rewind saltation is a part of the repercussion starter assembly that rewinds the starter cord after each pull . If , after the initial pull , the electric cord does n’t rewind and the engine wo n’t begin , then the issue is probable with a broken rewind saltation , and it call for supplant . Some chainsaw models earmark you to replace just the rewind spring . On other models , you have to replace the whole recoil starter .

Fix a flooded engine.

A fuel issue is one of the most uncouth reason why a chain saw wo n’t startle . If you have been seek to start the chain saw through the kick starting motor system , you may have unexpectedly flooded the locomotive with fuel . A common indication the engine has been flooded is the smell of gasoline in the air . If you believe fuel has flood the chainsaw railway locomotive , pull the starter cord several times while holding the throttle , dry and supervene upon the spark nag , and then try starting the chainsaw again .

Tried-and-True Advice

“ If you practice your chain saw infrequently like I do , I recommend using afuel stabilizer . I started adding it to my gas pedal , and it keep the fuel from deteriorate too quickly . That way , I do n’t have to interest about sometime fuel clogging up the carburettor the next time I involve the saw . ”

Make sure the choke setting isn’t activated.

Many chain saw have a choke position that is used to jump the saw in dusty conditions . This setting helps increase the air and fuel mixture ’s richness in the carburetor to better the fuel stream . If the choke is activate in mild or tender conditions situations or after the chain saw has been in utilization and is warm itself , it can promptly swamp the locomotive engine as it does not call for that amount of heat to set off . If you are troubleshoot the chainsaw at a ardent or mild temperature , verify the choke is not activate . If it has been on , the engine may be flooded , which can be solve using the steps above .

Replace old fuel.

As with many mechanical devices , the quality and quantity of the fuel used in a chainsaw can impact its cognitive operation and functionality . Check that your chain saw is properly fuel so the engine can run . Gasoline will start to degenerate if left fresh and session , so if the chain saw has n’t been started in a while , be sure to checker that previous fuel is not collecting inside the chainsaw .
