Hello everyone ;

While the egt values ​​increase normally during takeoff or ground run, the #1 cylinder drops back to around 150 degrees (C) after passing a value of around 700.
when i checked the spark plugs, i saw that only the first cylinder has darkened, the carburetor synchronization has just been done, the difference between the 3 and 4 cylinders is only 3-5 degrees (egt)
brand new carburetor sockets,brand new and checked floats.all rubber parts are almost new . And also run up magneto check is in limit no vibration or above 300 rpm drops 

whatever happens, it happens after 700-750 degrees. There is also vibration and noticeable power loss. I checked with a heat gun to see if it could be an Egt sensor. It works correctly.
