Why Predator Engines 61614 misfires?

  moraleskathrynAug 12, 2025
  Several factors can cause a Predator Engines engine to misfire: * Loose spark plug caps can disrupt the spark. Check the wire connections. * Incorrect spark plug gaps or damaged spark plugs can lead to misfires. Re-gap or replace the spark plugs. * Defective spark plug caps can also be the cause. Replace the spark plug caps. * Using old or low-quality gasoline can affect engine performance. Use only fresh 87+ octane stabilizer-treated unleaded gasoline, and avoid gasoline with more than 10% ethanol. * Incorrect compression can cause misfires. Diagnose and repair the compression issue, referring to the "Engine will not start: COMPRESSION RELATED" section for guidance.
