Piper Arrow- Lyconing io 360-c1c engine. No 3 cylinder runs fine when started but when you advance the rpm to 2000 to do the run up that cylinder goes dead, big vibration and temps for that cylinder go cold.
All others are fine and when you retard the RPM to 1000 number three cylinder comes back to life.
The cylinders were replaced about 170 hours ago. The injectors were all clean except number three and spark plugs have been replaced about 10 hours ago. Its done this the past 3 times I’ve started it, Neither changing magnetos left or right or selecting the electric fuel pump helps.
