It has been a few weeks of testing and implementing your suggestions, all of which I appreciate. After many blanks, I took the plane to my IA on Saturday. He pulled the prop through by hand and advised compression is very low on the problematic cylinder. He requested that I order a new jug and piston (wrist pin, rings, assembly, etc...) from J&J Air Parts. He said to plan for around $1,400 in parts plus 2-3 days of labor for replacement. What are your thoughts regarding the fix and time budget? For reference, this is a 1350 hour engine. Sent from my iPhone using Tapatalk

I checked the injector and it is good. However, I have not checked the spider. Will leave that task to my mechanic if needed. Thanks for the suggestions.

I will check the gasket. A $10 fix would be the cheapest outcome possible.

I guess I could wire the #3 probe to #1 readout on the EDM to rule out a problem with the wiring to the EDM.

I forgot to mention that one of my first suspicions was a failing CHT probe. I swapped the probes for cylinders 1 and 3. The problem stayed with cylinder 3, so, unfortunately, not a probe problem...

I was flying on a 2.5 hour cross country a few weeks back (before the apocalypse) and, seeing that it was a CAVU day and I was cleared direct to destination immediately after contacting departure, I had plenty of time to pay close attention to the gauges. I noticed an anomaly in cylinder 3 in that the temperature would rapidly rise 25-30 degrees hotter than normal, stay there fore a few minutes, and then cool back to normal. It did this for four or five waves during the flight. My senses were heightened due to the issue and it appeared to be accompanied by a very slight roughness and change in sound. However, I cannot confirm this to be true as the roughness could have just been a false perception based on what I was seeing on the gauges. During the flight, I performed a couple of mag checks and all was normal. EGT's were also all normal and showed no signs of change during the the temperature events. I have done all I can do to diagnose the issue. The fuel injector sleeve was clear of debris. Spark plugs were removed and looked normal. No visible signs of exhaust or intake leaks. Baffling looks perfect. I am guessing the next step is for me to take it to the shop for a compression check. Has anyone experienced this, or a similar, issue before? Suggestions as to the cause?

John, I could use a left inboard sender. What are you looking to get for yours? Sent from my iPhone using Tapatalk

Given this statement, what was the price for the job on N201TY? Sent from my iPhone using Tapatalk

I tend to over engineer. The mounting piece is thin with two holes in it for bolts. Just an added margin of error in the event it is ever subjected to loads. And yes, I did heat treat the steel after welding. Sent from my iPhone using Tapatalk

One of the concerns was keeping the correct geometry, so the brackets were sized to match the geometry of the shoulder harness in the front seat. There was absolutely no change to the airframe, so the FSDO agreed no 337 was required. The inspector just noted what was done and the approval in the file. Sent from my iPhone using Tapatalk

Fred, I looked, but believe the first mock up of the bracket fell casualty to a massive purge associated with a recent move. However, I was able to find pics of the actual brackets, mount location, and finished product: Sent from my iPhone using Tapatalk

Fred, I used Clarence’s method and got a field approval by my local FSDO. I still have a mock-up bracket I built at the hangar. I’ll take a picture and post it for you next time I go to the airport. Basic metal working skills and a cheap MIG welder are all that you need. Brandon

I am reviving this thread. Is anyone committed to go to JKA this weekend? I am a definite maybe. It really depends on whether my unreliable painters show up on Saturday morning. Sent from my iPhone using Tapatalk

I just had dejavu. Didn’t you organize one of these in the not so distant history and then not show up? Some lame excuse about the plane not making it out of the avionics shop in time? Lol. In all seriousness, these are always fun. Lulu’s definitely has the resources to accommodate a large group. If it takes a Milo’s burger to get Bob to come, I’ll get one on the way to the airport and toss it on the hat rack for him. Sent from my iPhone using Tapatalk

Ricky takes care of 4 Mooney’s at KEET, including mine. He’s a great guy. Sent from my iPhone using Tapatalk

I am still a few weeks off on the project. The timing may work out. Sent from my iPhone using Tapatalk

For those who have upgraded to CIES senders, I am not quite there yet. However, I could use an inboard sender for an early J. Anyone have one on the shelf you would like to sell? Sent from my iPhone using Tapatalk

We had a great turnout today. 13 Mooney’s in total! The restaurant was standing room only. It was great meeting those able to make the trip. Sent from my iPhone using Tapatalk

Looks like we are scheduled to meet up at Cullman (KCMD) next Saturday, Jan. 26. I am looking forward to having another good group. Last time we did this, I believe we had 9 Mooney’s fly in. So long as the weather is good, my wife and two daughters will be joining. Let’s get a head count on who all is confirmed. Sent from my iPhone using Tapatalk

Ratchet straps. Got distracted by someone during the pre-flight. Strap broke at apparently the exact time the ring exited the wing.

They will come out. Ask me how I know...

I just went the helicoil route at the last annual as the threads on the right wing were in rough shape. On mine, the clearances were too tight to install a nut on top. Also installed the Lasar tie downs. They were a bit expensive, but look great. Sent from my iPhone using Tapatalk

This is a pretty sharp group, so I am throwing out an off topic request. Does anyone know a good Java Developer I could hire to do some work for one of my businesses? Specifically, I have a custom web based CRM in need of modification. Thanks in advance. Sent from my iPhone using Tapatalk

Merry Christmas!!!! Sent from my iPhone using Tapatalk

Are we all confirmed for Jan 12? If so, I’ll put it on the calendar. Sent from my iPhone using Tapatalk
