  If your Harbor Freight Tools Portable Generator engine misfires, it could be due to several reasons. Check that the spark plug cap is not loose and that the wire connections are secure. Inspect the spark plug for damage or an incorrect gap, and re-gap or replace it as needed. Also, consider replacing the spark plug cap if it's defective. Ensure you are using fresh 87+ octane stabilizer treated unleaded gasoline, avoiding gasoline with more than 10% ethanol. If none of these steps resolve the issue, the engine may have incorrect compression, which requires diagnosis and repair.

  If your Harbor Freight Tools Portable Generator engine backfires, it might be due to impure or low-quality gasoline. Refill the fuel tank with fresh 87+ octane stabilizer treated unleaded gasoline, ensuring it has no more than 10% ethanol. Another reason could be that the engine is too cold; use cold weather fuel and oil additives to prevent backfiring. In some cases, a stuck intake valve or an overheated engine might be the cause, which would require a qualified technician to diagnose and service the engine. Finally, incorrect timing could also be the culprit, so check the engine timing.

  If your Harbor Freight Tools Portable Generator begins to operate abnormally, it could be due to a problem with the appliance itself.

Try lowering the number of items plugged into the generator to stay within the rated capacity, or consider using a more powerful generator.
