  If your ETQ Engine stops automatically, consider these possible causes: a lack of fuel in the system (add fuel to the tank), a clogged fuel line (clean it out), air in the fuel system (clean the system and replace the fuel), an adhered needle valve of the nozzle (clean or grind the nozzle, replacing it if necessary), a clogged air filter (clean it), or a sudden increase in load (decrease the load).

How to fix very black exhaust from my ETQ 170F?

  Stephanie MendezAug 15, 2025
  If your ETQ Engine's exhaust is very black, it could be due to an overloaded engine. Try decreasing the load, or if the driven machine isn't properly fitted, consider changing the engine. Alternatively, there might be a problem with fuel injection; check the injection pressure and spraying conditions, correcting or replacing the nozzle as needed. Insufficient intake air or air leaks could also be the cause; clean the air filter and identify and fix any leaks.

Why is the exhaust from my ETQ Engine very blue?

  A blue exhaust from your ETQ Engine often indicates engine oil is entering the cylinder. Check the oil level and drain any excess. It could also mean the piston rings are worn or their gaps are aligned, allowing oil into the combustion chamber; inspect or replace the piston rings, ensuring the gaps are not aligned. Worn pistons or cylinders, or worn valves or valve guides can also lead to blue exhaust; replace these components as necessary.
