I am troubled with high cylinder temps on my initial flight of the day. My equipment: RV-6, O-360, 1,000 hrs, Lasar ignition/Slick Mags, VM-1000 monitor.
Usually on my first climb out, my temps climb to about 430 deg, then level off and drop when leveling out. I can do a touch and go and the temps only climb to about 375. Normal cruise is about 360.
I replaced the intake gaskets and checked for induction leaks and rebuilt the baffle seals. Fuel flow on initial climb is about 17-18 gph. I turned off the Lasar system on one test flight with no change. Mags were recently inspected and are fine.
All cylinders run about the same temps with 2 and 4 slightly higher. Both cyl and EGT temps are quite uniform in cruise. All four cylinders are monitored so I doubt it is a probe problem. The Lasar monitors cyl temps and the probe checked out OK.
Oil temp is fine and I can keep it below 200 even on the hottest days.
Anyone have any ideas? Does the Lasar system "run" the temps up initially? Looking for answers, and thanks in anticipation.
