  If your TOLSEN TOOLS Portable Generator engine misfires, it might be due to several reasons. The spark plug cap could be loose, or the spark plug itself might be damaged or have an incorrect gap. A defective spark plug cap, old or low-quality gasoline, or incorrect compression could also be the cause. To resolve this, check the cap and wire connections, re-gap or replace the spark plug, replace the spark plug cap, use fresh 87+ octane stabilizer-treated unleaded gasoline (avoid gasoline with more than 10% ethanol), and diagnose/repair compression issues.

  Your TOLSEN TOOLS Portable Generator might stop suddenly because the fuel tank is empty or contains impure or low-quality gasoline.

To address this, fill the fuel tank with fresh 87+ octane stabilizer-treated unleaded gasoline (avoid gasoline with more than 10% ethanol). Also, ensure the engine oil is at the proper level, test or replace the fuel tank cap, have a qualified technician service the magneto, and secure the spark plug cap.

  If your TOLSEN TOOLS Portable Generator engine backfires, it could be due to impure or low-quality gasoline, the engine running too cold, a stuck intake valve, an overheated engine, or incorrect timing. To solve this, fill the fuel tank with fresh 87+ octane stabilizer-treated unleaded gasoline (avoid gasoline with more than 10% ethanol). Use cold weather fuel and oil additives to prevent backfiring. Have a qualified technician diagnose and service the engine, and check the engine timing.
