What to do if my Rato Gasoline Engine is overheating?

  Rebecca FloresAug 3, 2025
  If your Rato gasoline engine is overheating, consider these potential causes: * Check the oil level and refill engine oil if it is insufficient. * Clean the exhaust pipe if it is blocked. * Repair any damage if the shroud is leaking. * Clear any foreign matter blocking the cooling fins. * Reinstall the cooling fan securely if it is loose. Other possible issues include a deformed connection rod (replace it), worn cylinder, piston, or piston ring (replace the worn parts), improper adjustment of the engine governor (readjust it), or a burnt-out crankshaft main bearing (replace the main bearing).

Why does my Rato Engine have abnormal cylinder compression?
- B
  briana23Aug 20, 2025
  Abnormal cylinder compression in a Rato Engine can be attributed to several issues. The piston ring might be worn to or over its wear limit, necessitating replacement. A broken piston ring also requires replacement. If the piston ring is sticking, clear up carbon fouling. Ensure the spark plug is installed tightly with a gasket. Check for air leakage between the cylinder block and cylinder head, inspecting the cylinder gasket and the flatness of the contacting surfaces. Finally, check for air leakage in the valves, assessing their clearance and tightness, and repair if necessary.
