I went flying the Monday morning. Cooler and clear. On climb out the CHT for number 4 head went up to about 330 degrees as is it's norm. I climbed up to 3500 feet and trimed up for max cruise. The Jab 3300 was percing along just fine and it is normal as well that after a brief period the CHTs all drop into the 270-290 degree range. That day number 4 head only reduced down to about 320 and held there. I kept peeking over at the gage and waiting for it to drop. After about three times as long as it should have taken to drop I reached over and tapped the gage and it immediately dropped to 285 degrees. Now I know why I received that covetous Repairman's Certificate !! I am a certified Aircraft Instrument Expert ! So my tip is always tap your gage when the output isn't what it should be. Like banging on the TV for better reception. Best regards, Bill of Georgia 601XL-3300 120 hrs
