Check for any fuel issue: Check if fuel is sufficient, if it the fuel is the right quality and if it is the correct fuel/oil mix used, usually 40:10 or 50:10.

Check the fuel filter system: See if it is blocked. Use a fuel system cleaner to clean your fuel tank if it is. Do this by putting some fuel cleaner into the fuel tank, allow it to sit in the engine a while to circulate throughout the engine trapping all dirts, then Clean the fuel filter after this. Also ensure that the fuel filter is not faulty. Replace if it is.

Check the spark plug:  Starting issues can be related to a faulty spark plug. To know if the plug is working right, there will be a spark when it comes in contact with a wire.  Corroded spark plugs usually do not spark. Clean corroded plugs thoroughly and dry, then put it back into the saw, when you notice this.

The starter cord may be faulty: A Chainsaw starter cord is an indication of the engines compression. If you notice  when pulling the  cord that it’s a little bit sagged, it may be that the engine compression is too low ( in this case the pressure to build power from the engine will be low hence it won't be able to kick start) you may have to fix the saws engine compression, if this is the case.

Check the air filter: dirts, are filtered off by the air filter, so It doesn’t reach the combustion chamber. If the air filter is clogged, it becomes difficult for air to reach the combustion chamber, and this could cause starting problem. Locate the air filter with your manual and Clean off dirts in it.

Flooded engine: if your engine is pumped with too much fuel, it becomes flooded and will not start.  Unflood  the engine by simply removing the spark plug to dry.

Check for blockage in the carburettor: when fuel is left in the tank for too long it causes blockage in the carburettor. Blocked carburettor can cause starting issues in the saw. If the carburettor is blocked it needs to cleaned thoroughly ( cover the throttle when doing this), and the fuel in the engine changed. After doing this your adorable wild chainsaw should start working.

Adjusting the Carburettor of your Husqvarna Chainsaw

The chainsaw carburettor’s job is to determine by measurement, the right amount of fuel ( not too much and not too little) that will mix with air before entering the engine ensuring that the engine works right

The carburettor has three adjustment screws.  H – High (regulate the air/fuel mix during high RPM), L- low( regulates the air/ fuel mix during low RPM), T- idling.( regulates the amount of fuel that gets into the carburettor while the throttle is pressed(idling).

Adjust your Husqvarna Saw with these Quick Steps:

L Screw: adjust the L screw by screwing it to the left while the engine is running. Do this till the Engine almost stops. After that slowly turn the screw towards the right ( as you do so, you will hear the engine idling smoothly) keep screwing until the engine starts to accelerate smoothly.

T  Screw: Start screwing it clockwise until you notice movement in the saw, then turn  anticlockwise slowly till the chain stops moving. The engine will be idling smoothly.

H Screw: Turn it anticlockwise continuously till it no longer screws. At this point the saws engine will begin to sound roughly. If you noticed this, start turning  clockwise until the engine sound smoothly, then push the throttle a little.
