  If your Forest King Chainsaw engine won't start, there are several potential causes. First, make sure the ignition switch is turned ON. If the engine is flooded, reference the digital starting section of this manual. Also, check if the fuel tank is empty and fill it with the proper fuel mixture if needed. A faulty spark plug can also prevent the engine from starting, so install a new one. Finally, ensure that fuel is reaching the carburetor by checking for a dirty fuel filter (replace if necessary) or a faulty fuel line (repair or replace if necessary).

Why my Forest King Chainsaw engine will not accelerate properly?

  Scott TylerAug 12, 2025
  If your Forest King Chainsaw engine won't accelerate, lacks power, or dies under a load, it could be due to several reasons. Check if the air filter is dirty and clean or replace it. A faulty spark plug can also cause this issue, so clean, replace, or correct the gap. Ensure that the chain brake is disengaged. If these steps don't resolve the problem, the carburetor may need adjustment, so contact an authorized service dealer.
