Have you checked the seal on your fuel caps? When I first got my J one of the caps wasn't sealing tight. When I topped the tank on that side the fuel level would contact the rear part of the cap during a climb and the low pressure on top of the wing would pull fuel out. I could smell fuel when that was happening and during one flight I could actually see the fuel coming out. Once I replaced the o-rings and tightened the cap a bit it stopped doing that.

SkyVista at KMRT has a good reputation with Mooneys. There's a guy over in Zanesville that @steingar uses. Maybe he will stop by and provide more info. I have the folks at KOSU do most of my maintenance. They are probably more expensive by I have known a couple of them for years since before they were at OSU.

Where in Ohio are you located?

The one next to it looks like it says M-RC217A. With sequential numbering like that are you sure those aren't just identifiers for the connectors/wire bundles? With a bunch of nearly identical connectors they probably labeled them to make it easier to get them back in the right spot if you disconnect more than one at a time.

FWIW, Mooney advises against this. https://www.mooney.com/wp-content/uploads/2020/12/SIM20-114.pdf I am not advocating for following or not following this guidance. I just thought you might want to be aware of this service instruction from Mooney. Someone will be along shortly to tell you why you should ignore this guidance from Mooney.

The applicability paragraph lists engine series like TO-, LTO, and TIO-360 that aren't anywhere in the table so clearly the table is not a comprehensive list of applicability. It is definitely a poorly written AD but I think you will have a hard time convincing the FAA that the M20E and M20F aren't included.

The comments aren't regulatory. Only the text of the actual AD matters. You can see under applicability that it give the series identifiers for the hubs which match what is listed on the type certificate for the E and F models and specifies that they are installed on Lycoming engines including the IO-360 series.. The list of aircraft has the following caveat: "These propellers and engines could be installed on, but not limited to:" Which means the list isn't comprehensive and you have to determine applicability from the prior text.

The list of most recent versions of Mooney technical documents can be found here: https://www.mooney.com/wp-content/uploads/2020/12/Mooney-Technical-Publications.pdf See page 10 for M20K. It looks like the most recent M20K parts manual is from 1998 and the maintenance manual is 2014.

In the clinical trials they divide the volunteers randomly into two groups and vaccinate one of the groups. Then they wait while both groups are potentially exposed to the virus through normal activities. Once they see a certain number of cases in the unvaccinated group they compare that to the number of cases in the vaccinated group and calculate the efficacy. For most diseases this can take years but in a pandemic they quickly reached a useful number of cases in the two groups. In both the Moderna and Pfizer trials they found about 95% efficacy and nobody in the vaccinated groups had a severe case of COVID-19.

Methylene chloride is fairly volatile and doesn't leave a residue. It has a lower boiling point than acetone. There is little reason to be concerned about long term effects on aluminum. Of course you are unlikely to be able to buy any unless you work in a lab so it's probably a moot point either way.

Polyurethanes are a class of polymers that can contain different levels of crosslinking and branching. What may work for one specific polyurethane may not be effective for others. The level of crosslinking in the tank sealant material will determine how effective any of these solvents are. Even DMF may just cause it to soften and swell but that may be enough to remove it. Heat may help but be careful with any heat sources in an enclosed space with solvents.

I'm more of an organic/medicinal chemist so I haven't done any polymer chemistry in a long time but I seem to recall that crosslinked polyurethanes are extremely solvent stable. You probably won't be able to get it to actually dissolve. You may be able to get it to swell and separate from the metal with something like methylene chloride.

I'm pretty sure Raymond just copy/pasted that from the internet. https://www.researchgate.net/post/How-do-I-dissolve-a-polyester-urethane-resin-after-it-has-hardened

The simple solution is to buy one of the new Mooney Ultras with a second door.

Can't you just look at the adapter rings on each tank and see if the notches for the fuel caps are in the same positions?

In my old M20D I found that the heater produced plenty of heat but little airflow. If I opened the vent just a little along with the heat it helped push the warm air into the back seat area.

Looks like the same annunciator as I have on my M20J. The gear down light is the same color on mine. The floor indicator is green.

Have you looked at the original data from when it was weighed at the factory? That information was in the POH for my 1963 M20D.

I have no experience with weighing airplanes but a 50 lb difference between left and right mains looks odd. Is it normal to see that much difference? Is it possible the right main number got recorded wrong?

On the 650 it's even easier. Just go to the waypoint page and there's a "create WPT" button. If the upload doesn't work just do it on the 650. People who live in less crowded areas still fly in busy airspace. That's one of the reasons we have Mooneys. Oh, and the sun sets and we get weather here too.

I think they meant to create and save it while on the ground. Then you can just add it to your flight plan like any other waypoint. https://www.manualslib.com/manual/302087/Garmin-Gns-430.html?page=133

Did you only use car seats in your car because you were legally required to? I always had the kids in car seats in the plane because the kids were too small for the adult-sized seat belts to properly protect them in the event of an accident. The lack of shoulder harnesses in the rear seat of short body Mooneys was another reason to favor using the car seats.

We thought about putting a kid in the front right seat but I tested it on the ground and the car seat interfered with the yoke.
