What to do if Husqvarna Pole Saw engine starts but stops again?
If your Husqvarna Pole Saw engine starts and then stops, it could be due to incorrect fuel type. In this case, empty the fuel tank and refill it with the correct fuel. Alternatively, a clogged air filter may be the cause. Clean the air filter to resolve this issue.
Why no fuel flows in my Husqvarna 525P4S?
If no fuel flows in your Husqvarna Pole Saw, it could be due to several reasons: a poor carburetor adjustment, which requires adjustment; a blockage inside the carburetor, requiring cleaning; a blockage in the fuel filter, so you should clean or replace the fuel filter; or fuel hose damage or blockage, which also requires adjustment.
What to do if there are sparks at the spark plug on my Husqvarna Pole Saw?
If there are sparks at the spark plug but the Husqvarna Pole Saw still won't start, it could be due to several reasons. You might have excessive fuel intake, in which case you should discharge the excess gas. The fuel could be too thick, requiring you to repair or replace the carburetor. Overflow could also be the problem, so adjust or replace the carburetor. Alternatively, the air cleaner may be soiled; clean it in a gasoline mixture and dry it thoroughly. Finally, poor quality fuel could be the culprit; replace it with good quality fuel.
How to fix no sparks at the spark plug on a Husqvarna 525P4S Pole Saw?
If your Husqvarna Pole Saw has no sparks at the spark plug, it could be due to a few reasons. The spark plug electrodes might be wet, in that case you should dry them. Carbon may have built up on the spark plug electrodes; remove the carbon or replace the spark plug. The spark plug insulator might have cracks, so replace the spark plug. Also, the gap between the spark plug electrodes may be too small or large, so adjust it to 0.65 mm.
What to do if fuel flows, but compression is poor in Husqvarna 525P4S?
If your Husqvarna Pole Saw experiences poor compression despite fuel flow, several issues could be the cause. The spark plug might be loose; tighten it. There could be wear or damage to the cylinder, piston, or piston rings, requiring replacement. Alternatively, gas may be leaking from around the cylinder and crankcase; replace the gasket with a new one and re-assemble.
