A year later when I had the exhaust off for an unrelated issue, I noticed the spring was gouging the stainless steel tube. Every place the coil touched the tube it ground in a recess. I removed the spring. It hadn't made much difference anyway. What did make a big improvement was to take the intake air from within the engine compartment. That brought the temperature rise up substantially. Although the temperature gauge only indicates a 15 deg F rise it does enrichen the mixture enough to cause the engine to run rough until leaned. This change, of course, prevents the use of the heat muff for cabin heat. Chris Zavatson N91CZ L360 std
