I'd like to put a CHT (Aircraft Spruce, most likely) on my engine, but it seems the spark plug location requires either some grinding of metal, which requires removing a bunch of stuff, that requires removing the engine, etc...
Is there another place to install a CHT? There is a CHT sensor on the engine, but doesn't that have to stay? Or, can I attach a gauge to that one? The only alternative I was able to find was this thread (thanks 76-914) about bending the wire 90 degrees on the spark plug install option: "Like Mark said it's just a piece of metal so open it up a bit so that the plug rotates freely in the ring. Then with the ring on the plug bend it 90 degress. Now turn the plug again to be sure that it rotates freely after the bend. Insert plug into #3 with the wire at the 9 o'clock position (or towards the rear) and tighten. There seems to be a bit more room for the lead when installed in this position. at least my head had a bit more room to the left side of the plug. BTW, I left the plug washer on so I would not twist the sender." |

There's an alternative, I also didnt want to bend it and have it coming up thru the spark plug hole/grommet so I drilled a hole perpendicular to the plug and installed it with a grommet.
 Like everyone has said, put it under #3 plug. |
