From: "fighterguy" Hello All, I would like to ask your opinion on an engine issue: I have one cylinder on my M14P that is running about 40 deg C hotter than the rest. (I have a fancy, 9 cylinder CHT instrument, like a JBI). It was #3 running hot I swapped the leads with #4 cylinder and the indication followed the cylinder - #4 is indicating hot now = so, in fact the cylinder #3 is running hot and indicating properly I think....? I checked the intake tube for tightness and such, pulled the plugs - they look OK, perhaps a bit white....ish (hot) but not real bad. I am not sure what to check now or where to look for the problem........and ideas? I really appreciate any advice or help you can provide. Thanks all!

From: "fighterguy" Hey Dennis, Sorry for the confusion. #3 has been indicating hot for a while, but only at high power. At idle and low power it was normal. So I swapped leads with #4 cylinder. Then #4 was indicating hot and #3 was normal - so I assumed the leads are OK and the #3 cylinder is actually running hot. :) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=488487#488487 ________________________________ Message 5 _____________________________________ Time: 12:32:06 PM PST US From: "A.

No, I disagree.=C2- If after swapping the probe #3 was normal and #4 was reading hot, then your problem is most likely a bad lead.=C2- ie:=C2- The problem followed the probe.=C2- Did not stay with the same cylinder.D ennis On Wednesday, April 3, 2019, 3:23:30 PM EDT, fighterguy wrote: il.com> Hey Dennis, Sorry for the confusion.=C2- #3 has been indicating hot for a while, but only at high power.=C2- At idle and low power it was normal.
