Why Husqvarna Chainsaw will not run at full throttle?
- DDaniel WilliamsAug 17, 2025
If your Husqvarna Chainsaw won't run at full throttle, consider these potential causes: a blocked air filter, blocked fuel tank ventilator, blocked fuel filter, or a blocked fuel line. Other possible issues include a loose or damaged fuel line, leaking or blocked impulse channel, a loose cover on the carburettor pump side, or a faulty pump diaphragm. Also, check for a leaking manifold, loose carburettor mounting bolts, a control system that is set too low, damaged or incorrectly assembled control system, leaking control diaphragm/cover, a sticking control system, or a blocked muffler. You can start by adjusting the H-screw.
