What to do if my Direct power Chainsaw engine will not start?

  Margaret VasquezAug 2, 2025
  If your Direct power Chainsaw engine won't start or runs only briefly, several factors could be at play. First, ensure the ignition switch is set to "I". If the engine is flooded, fill the tank with the correct fuel mixture. An empty fuel tank is another common cause, so replenish it with the proper fuel mix. A faulty spark plug can also prevent starting, so install a new one. Lastly, a dirty fuel filter or a kinked/split fuel line can impede fuel flow to the carburetor; inspect and replace or repair as needed.

Why Direct power Chainsaw engine will not accelerate?

  If your Direct power Chainsaw engine lacks power, won't accelerate, or dies under a load, start by checking the air filter; clean or replace it if dirty. A fouled spark plug can also cause these issues, so clean, replace, and regap it. Ensure the chain brake is disengaged. If these steps don't resolve the problem, the carburetor may need adjustment, and you should contact an authorized service dealer.
