Inspect your starter chain and tensioner for excessive slack or wear. Ensure the engine ground wire connection is clean and tightly secured — a loose or corroded ground is the leading cause of intermittent starting issues and low cranking power. CRITICAL FITMENT CHECK: Small 4-stroke engines use either an \"Upper Mount\" (above the cylinder) or a \"Lower Mount\" (underneath the crankcase) starter. This is a lower-mount unit. Physically verify your engine's mounting position and confirm the 68mm bolt-hole spacing before ordering.
