Adjusting the valve lash on a Honda GX270 engine is important for maintaining optimal performance and efficiency. The process consists of five steps:

  1. Removing the Valve Cover – This will give you access to the valve train components that need to be adjusted.

  3. Checking Valve Clearance – Use a feeler gauge to check that clearance between 0.15mm and 0.25mm, depending on temperature conditions and whether it’s an intake or exhaust valve respectively.
  4. Adjusting Valve Lash – If necessary, use a wrench to loosen lock nut then adjust screw with screwdriver until proper clearance achieved before tightening lock nut again; repeat for other cylinder where applicable
  5. Rechecking Valves – After adjustments have been made, recheck valves using feeler gauge one last time for accuracy
