When your chain saw starts leaking fuel, it’s time to discontinue its engine and also find the root of the problem. Leaking gas is not simply smelly and messy, in addition, it poses a fire hazard and might be harmful to your health. Your first step must be to wipe down the whole outside of the chainsaw to get rid of any debris, gunk or gasoline. Then inspect the chain saw’s body to look for the source of the leak.
Fuel Tank Cracks
Many modern chain saws include plastic parts that can wear or break. One such area that may be produced from plastic is that the fuel tank where the fuel is stored. Plastic fuel tanks may break or crack when they are hit against an object or even dropped onto a tough surface.
Worn Fuel Lines
The fuel lines which deliver the gas in the tank to the carburetor are generally made from rubber or plastic. Like the fuel tank, these parts can crack or break out of abuse — however they’re also able to only wear out. In case you haven’t used your chain saw in a while, or it’s been stored in a cold, dry place, the fuel lines may become brittle and crack. Check them before you start using the chain saw for the season.
Fuel Cap Damage
The fuel cap which you take on and off to fill up the tank may even get damaged from mishandling. It is rather simple to drop a gas cap to a hard surface, or to crush it under the burden of a heavy log. Inspect the cap of the gas cap and look for cracks, but additionally inspect the threads around the bottom of the cap. If even one thread becomes chipped or cracked, it can cause fuel to leak out while the chain saw is in use.
The Carburetor System
For any motor to run smoothly, it requires the perfect mixture of fuel and air. The duty of the carburetor will be to deliver that proper mix — however if the rubber or plastic seals and also gaskets surrounding it become damaged or worn, fuel may leak out instead. In some instances, a easy, cost-effective gasket replacement is going to do the job; at different scenarios, you may want to rebuild the whole carburetor to repair the problem. If you have ruled out the fuel tank, fuel lines and fuel cap as the source of your issue, take your chain saw to a certified repair center to help diagnose your problem.
