Hi, My55. Sounds like overheating from a failing water pump. Replace the impeller. It may not be the problem, but it should be done regularly anyway. Other possibilities are a poorly vented fuel tank or obstruction in the fuel lines.<br /><br />Red sky.<br />JB

check compression and plugs could be carbon build up fuel line filter carbon build up can be cured
