Why does my Pulsar Portable Generator engine stop suddenly?
- J
  Joann ParsonsAug 14, 2025
  If your Pulsar Portable Generator engine stops suddenly, first, add engine oil to the correct level, remembering to check it before each use. If the fuel tank is empty or contains impure or low-quality gasoline, fill it with fresh 87+ octane stabilizer-treated unleaded gasoline, avoiding gasoline with more than 10% ethanol. A defective fuel tank cap can also create a vacuum, so test or replace it. Other potential causes include a faulty magneto (have a qualified technician service it) or a disconnected spark plug cap (secure the cap).

  Karen BarnesAug 21, 2025
  If your Pulsar Portable Generator engine misfires, check the spark plug cap and wire connections to ensure they are secure. Re-gap or replace the spark plug if it's damaged or has an incorrect gap. If the spark plug cap is defective, replace it. Use only fresh 87+ octane stabilizer-treated unleaded gasoline, avoiding gasoline with more than 10% ethanol. Diagnose and repair compression issues, referring to the 'Engine will not start: COMPRESSION RELATED' section.

  Heather JohnsonAug 25, 2025
  If your Pulsar Portable Generator engine knocks, fill the fuel tank with fresh 87+ octane stabilizer-treated unleaded gasoline, ensuring not to use gasoline with more than 10% ethanol. Avoid exceeding the equipment's load rating. If the issue persists, have a qualified technician diagnose and service the engine for potential problems such as incorrect spark timing, deposit buildup, or a worn engine.

What to do if my Pulsar PGDA70BiSCO Portable Generator won't start and I suspect a compression problem?
- J
  Jason GarciaAug 27, 2025
  If the Pulsar Portable Generator engine will not start due to compression issues, pour a tablespoon of oil into the spark plug hole, crank the engine a few times, and try to start it again. Tighten or replace the spark plug if it's loose or broken. If the problem continues, have a qualified technician service the cylinder head for potential issues like a loose cylinder head or damaged head gasket, or adjust/repair valves and tappets if they are misadjusted or stuck.

  Marie BrownAug 30, 2025
  If your Pulsar Portable Generator engine backfires, fill the fuel tank with fresh 87+ octane stabilizer-treated unleaded gasoline, avoiding gasoline with more than 10% ethanol. Use cold weather fuel and oil additives if the engine is too cold. If the issue persists, have a qualified technician diagnose and service the engine for potential problems such as a stuck intake valve or an overheated engine. Also, check the engine timing.
