Why Predator Engines 79cc will not start?
- L
  Larry WilliamsJul 31, 2025
  There are several potential reasons why your Predator Engines engine might not start. It could be fuel-related, such as an empty fuel tank, a closed fuel valve, the choke not being in the START position, using gasoline with more than 10% ethanol, low-quality or old gasoline, the carburetor not being primed, dirty fuel passageways, a stuck carburetor needle, too much fuel in the chamber, or a clogged fuel filter. Try filling the fuel tank, opening the fuel valve, moving the choke to the START position, using fresh 87+ octane unleaded gasoline, pulling the starter handle to prime, cleaning out the fuel passageways, gently tapping the side of the carburetor float chamber, turning the choke to RUN position and airing out the chamber, or replacing the fuel filter.

  If your Predator Engines engine stops suddenly, it could be due to several reasons. The oil level might be low, the fuel tank could be empty or filled with impure gasoline, the fuel tank cap might be defective, the magneto could be faulty, or the spark plug cap might be disconnected. Try filling the engine oil to the proper level, filling the fuel tank with fresh 87+ octane unleaded gasoline, testing or replacing the fuel tank cap, having a qualified technician service the magneto, or securing the spark plug cap.

  A Predator Engines engine might misfire due to a loose spark plug cap, an incorrect spark plug gap, a damaged spark plug, a defective spark plug cap, old or low-quality gasoline, or incorrect compression. Check the wire connections, re-gap or replace the spark plug, replace the spark plug cap, use only fresh 87+ octane unleaded gasoline, and diagnose and repair the compression.

  A Predator Engines engine may knock due to old or low-quality gasoline, the engine being overloaded, or incorrect spark timing. Try filling the fuel tank with fresh 87+ octane unleaded gasoline and not exceeding the equipment’s load rating. If these steps don't resolve the issue, have a qualified technician diagnose and service the engine.

  If your Predator Engines engine is backfiring, it could be caused by impure or low-quality gasoline, the engine running too cold, a stuck intake valve, an overheated engine, or incorrect timing. Try filling the fuel tank with fresh 87+ octane unleaded gasoline, using cold weather fuel and oil additives. If the problem persists, have a qualified technician diagnose and service the engine, or check the engine timing.
