Have your mechanic clean and re-rack the KN-72 Nav converter. It should be located in the tail. Sometimes a bad connection there can cause issues. Definetly re-calibrate the KA-51. What do you mean you wait and then start aligning it? The gyro in slave mode should self-align once power is applied. It does a quick align in the first 120 seconds, and then fine tunes from there. You should not have to align it yourself just leave the switch in the "slave" position. It's going to be much more accurate than your heading from the whiskey compass. By the way, when was the last time your compass was swung?

@dkkim73 very nice! GPI is my preferred spot to clear customs now that GTF is charging a fee. We were “stuck” there for a couple days last month when my starter clapped out. The boys over at Rocky Mountain had a new SkyTec installed for me within two days and we were back on our way. Kalispell city airport is neat, there are some nice people there. Take a flight up past hungry horse dam, it’s a sight to be seen! As you’ve seen, Glacier Jet center is no more, but even though it’s now a “big box” FBO, I still get treated really well even in my little Mooney.

If you're getting negative amperage it means the battery is discharging. Do you not have a "High / Low Volts" annunciator? What's the voltage showing while the ammeter indicates discharge?

Silicon.

So was it the engine driven fuel pump, or is that one Magneto suspect?

How the hell are these installs getting out of the shop in the first place?? Some very concerning stuff come to light in this thread.

Bump: Reasonable offers welcome. No good to me collecting dust.

The sensor is usually located on #3 because it’s the hottest cylinder. So, you’ve flown it a few times since trying to diagnose this issue, have you fixed the baffles yet?

I was referring to your last post where your A&P diagnosed a “faulty CHT gauge”.

At least that leaves you some money to get this stuff fixed. So, you're sure the CHT gauge is working properly?

The paint on that thing makes it look like it’s been washed with a wire brush. How does a Mooney have an “inadvertent gear retraction after landing?”

Doesn’t matter when something was last replaced I’ve learned. Treat it like it’s all susceptible to failure.

Pre buy inspections are money well spent, no matter if you end up buying the aircraft, or walking away from it. Sure, you spent $5000 on it, but that likely saved you tens of thousands of dollars down the road had you actually gone through with the purchase. Money well spent as far as you should be concerned. Trying to recoup the cost of a failed pre buy online? Why would anyone go there? It’s clearly bad enough to warrant walking away, even with $5000 already invested. That screams that it’s really bad. Pretty much all that a potential buyer needs to know. The details are irrelevant at that point.

It’s probably your push to talk.

The side baffle seals might be okay, but that aft one is horrible. You can see where a large section of it is folded backwards, and there’s a giant hole where there should be a duct attached. If you’re not using ducting there, plug it off. I bet by fixing those two things alone, you’ll drop your CHT’s by 50*. Didn’t you recently purchase this airplane? How did any of this make it past the pre buy inspection?
