Did every trick we could find on the web, while waiting for ur friend Jim's plug tool to find exat position of TDC. Mags were way out. Should have been 25 BTDC but what we found was Left at 26 and right at almost 28. Adjusted and flew get flight with 30C at takeoff and WOT e highest was a short period of time at 400 then everything settled down to under 370. Ottom line is if you have hi CHTs fix the baffle leaks and accurately check e timing
