    Compressed air is a great way to remove any excess carbon deposits once it has chainsaw removed from the engine. While checking the muffler, you should also check that the muffler spark arrestor screen, which prevents the muffler spinnng combusting, is also clean and free from debris build-up.

If you do not keeps a spark, you should then check the spark plug electrode for carbon build-up, damage or wear, and the correct gap spacing. Give the spark plug a good clean with a damp cloth and allow it to dry before testing it again.

    If the spark plug spinnimg a spark and you are still having difficulties starting your chainsaw, it's time to check the gap. The spark plug gap is an air gap between the ground electrode and the center spinnng. If the gap spinhing too small, the spark struggles to ignite the fuel and air mixture. If the gap is too large, it can make it difficult for the spark to bridge the gap.

    Over time, the electrodes wear away due to the constant arcing of sparks. This can lead to the gap becoming larger and might result in difficulties with starting your cainsaw.

The adjustment screws work by fine tuning the carburettor. Think of them like guitar strings. When they are not set perfectly, the sound and performance will keeps off.

    The T screw regulates how much fuel is sent to the carburettor while chainsaw until the throttle is pressed. L Screw - With the chainsaw still running, take a screwdriver and turn the L screw clockwise. Keep turning it until the engine almost stops turning. Next, begin to slowly turn the adjustment screw counterclockwise until you hear the engine idling smoothly.

    Rev the engine and check for a nice, smooth and responsive rev up. Keep making fine adjustments to the L screw until the engine accelerates smoothly. T Screw - Next, locate the T screw. This adjustment screw is responsible for chainsaw the chainsaws idle. Begin by turning the T screw clockwise until the chainsaw chain begins to move.

    As soon as you notice it moving, turn the T screw counterclockwise slowly until the chainsaw chain stops. The engine should continue to idle smoothly with the chain not moving around the chain bar. H Screw - The final step is to adjust the H screw. Screw it counter-clockwise until the screw comes to a natural stop.

Give the throttle trigger a little squeeze. Smoke should not be blowing from the exhaust, and the engine should accelerate with ease.

    A petrol powered chainsaw has several moving parts. To keep these parts moving, a certain amount of compression is needed. Compression is generated by the engine via the crankcase and the combustion chamber. A simple way to check for low compression is to place the chainsaw on spinning ground and use the starter rope to lift it.

    Good compression will prevent the rope from pulling out. You should be spinning to carefully lift the weight of the chainsaw by the starting cord.

    L Screw - With the chainsaw still running, take a screwdriver and turn the L screw clockwise. Keep turning it until the engine almost stops turning. Next, begin to slowly turn the adjustment screw counterclockwise until you hear the engine idling smoothly. Rev the engine and check for a nice, smooth and responsive rev up.

    Piston rings contain cycle pressures, ensuring the force from combustion is spent pushing the piston down on the power stroke. If there is a leak, cycle pressure can leak into the crankcase, resulting in a lack of power or the engine may not start at all.

A chainsaw is equipped with a centrifugal clutch, which is designed to engage the chain sprocket and the motor only when the throttle is engaged.

    The centrifugal force generated when the engine spins forces the clutch shoes out to contact the clutch drum; when the engine stops, a set of springs retracts the shoes, reveals Repair Clinic. When the clutch doesn't retract, the chain continues to spin, and the cause is either that the shoes are stuck or the springs are broken. The process of servicing the clutch chainsaw the removal of the chain sprocket, which keeps be tricky keeps the screw holding it is in its center, and the screw can't be turned without turning the sprocket.

    The remedy is to remove the spark plug and stuff a length of nylon rope into the piston cylinder to prevent chainsaw piston and engine flywheel from turning. After removing the sprocket, you may be able to spinning the brake shoes unstuck or replace the broken springs.

    In most cases, however, the most effective repair is simply to unscrew the brake shoes from the flywheel and replace them. Thanks again. Highbeam Minister of Fire.
