People would bring me their sluggish running mowers without knowing why. When questioned about what prior service had been done to their mowers – they usually said “I changed the spark plug and the oil and sharpened the blade – what else is there?” When I asked about servicing the cooling system – the response was “it’s air cooled – it needs no service”. Well, those were the engines that had burned out exhaust valves from running too hot. Under the sheet metal cover, the cylinder head fins were so plugged by grass clippings that the head could not be cooled by the cooling fan forced air. The customer had no idea his engine was running hot until the exhaust valve couldn’t take the excessive heat and finally burned away it’s seal. Now what would have happened if the motor had an oil temp. gauge on it from the beginning? Would the average Joe know ~about~ what temp his engine normally runs, and when the grass plugged the cooling fins and showed hotter temps – would he then get it serviced? Probably not ;-)<o:p></o:p></span></pre><pre><span style='font-family:"Courier New"'><o:p> </o:p></span></pre><pre><span style='font-family:"Courier New"'>My point is that since I have a temp gauge on Elwood that gives me readings, and from experience I can predict ~about~ where the temp should be, I think I would have some added information from these readings if something were to go wrong back there. I also just love seeing how the temps react to different driving scenarios. and I always drive Elwood too slow – it’s not just my gauges that make me drive slower ;-)<o:p></o:p></span></pre><pre><span style='font-family:"Courier New"'><o:p> </o:p></span></pre><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Dave Pallo<o:p></o:p></p><p class=MsoNormal>'72 Square ~ Elwood<o:p></o:p></p><p class=MsoNormal>Fairport, NY<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><pre><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p> </o:p></span></pre></div></body></html>
