[DML] Re: Water Pump Blues!

Sorry, I don't agree with your analysis. The engine will not run hot with
an overly lean condition and will not cook the spark plugs. The CIS fuel
system will only operate within a very narrow range of air / fuel mixture
therefore the engine will not run if the mixture is too lean or too rich.
