Fix

Question about some power settings and your thoughts about it. If you fly at 65% or below it said that your fuel flow settings doesn't matter since you then are out side the red box. So for 65% on -MB/SB Engine you have either: 65% LOP at 10.4g/h (you can have any preferred setting on MP/RPM, 27" / 2500) and then you are outside red box. 65% ROP, Key #50, ie: 25" / 2500 or 26" / 2400 and fuel flow at 12.6 g/h for 100 ROP. So if I want to fly 65% ROP 25" / 2500 (Key: 50) can I set what ever fuel flow I want, long as TIT and CHT has good temps? Like 11.5 g/h Peak TIT long as TIT is on safe temp like 1500-1600 and CHT below 380.

I also have around 140ktas +/- 5kt at 1000-4000ft at 26"/2500 9.8g/h.

Sorry... I get all from 0.3 to 0.6 depending on when I do it. Guessing that I have OK Gami Spread, and it's my ignition that is the issue. Anyway, we have checked different things, and if it don't work as I hope after a SureFly and carefully timed left magneto, than I will try to get Gami Injectors.

Interesting topic, since I'm trying to get my SB engine to run more smooth on LOP. Maybe I don't do it correctly when leaning to LOP side, but I'm pretty sure that I'm close to doing it right. I have an -SB engine and use 25-27" and 2500rpm and use 9.6g/h. (~ 60% power) When I checked with my engine monitor I'm ~20 LOP but have some roughness. This is from 2000feet to 5000feet. Will test more soon as my aircraft is ready from annual. Want to test 65% with 10.4g/h Since I more or less just bought my M20K 252 I'm still learning. My goal is to have a smooth running engine at LOP. Have FireWire plugs, checked for correct gap. I'm also installing a SureFly at this annual, (Right Mag) and that was the mag that was running most rough for me,

Mine is also "twisted" and don't fit perfectly. Also like yours like it's more narrow in one end restricting the airflow. I have full power at takeoff and the Alt Air don't lit up. This annual we done some work to make it fit better. It got much better, but not perfect as I would like. Will see if I can take some pictures next week.

This looks more like there was an ongoing leak while it got painted, than if you compare with G100UL paint problems.

My direct driven alternator just came back from an 500h inspection and both brushes was worn 6mm left on them. Also drive coupling was worn, so it was out of spec. This on ~600h

Sadly not. it was sent for overhaul, $6200. Then it needed to be repaired for $8000 Almost same as for a new. Problem is that MT has 36weeks delivery for a new.

Nice to hear that they are slowly sending them out. I must have been lucky to got mine from them.

I'm doing my first annual now, and I've been at the workshop helping out best as I can. Also I have an independent mechanic, he is very friendly and we are building a "friendship & trust" together. With a helpful mechanic owning an aircraft is much more easy! Last tip, open your wallet because you don't know what you will find :-) - Propeller sent for overhaul = New Hub, 3x Bearings and repair of 2 blades (MT PROP) = $15000 - Alternator also sent for 500h inspection (Direct driven) = Need of new Drive coupling and new brushes = $2500 Hopefully no more surprises, but we are almost done. This annual we fixed all small stuff I found or didn't like. Repaired Fuel Sender, so I now can see how much fuel I have in left wing :-) New - Air intake tube to engine (Old was scuffed quite badly) Repaired JPI 701 EDM Display. Replace one of the magnetos with a new SureFly Ignition. New Airfilter after 500h Repaired side wall interior from some small cracks.

What altitude is the M20K 252 certified for? M20K 231, has 25000 feet, listed in POH. M20K 252 has 28000 feet, listed in POH. M20K Encore has 25000 feet, listed in POH. What do an upgraded M20K 252 with Encore mod have? 25000 feet or 28000 feet? I'm looking on a uAvionix AV-30-C and this has a limitation for any aircrafts that are certified above 25000 feet. They list M20K in their AML, but has a note about the 25000 feet limit.

So, we already attach unapproved parts and if we can attach a very similar as the original I personally don't care. And who says it's for aviation, it could be for my lawn mover and the gauge happens to fit my Mooney. Of course it would be even better if the part was 100% legal!

Would it be possible to order a "custom" gauge directly from Rochester specified for what we are looking for? Then we can do a group buy here at MS to get the quantity up. I would order 2-4pcs depending on price just to have in stock.

Been thinking about this. If I want to fly 65% LOP on a 210HP Engine (GB/LB/MB) we can use this formula above. But I have an -SB with 220HP, and the same formula says that 65% is 10.5gph. And 10.5gph on the 210HP would be 68.5% Owners with -SB engines do you calculate fuel flow / LOP for 210HP or 220HP?

It appears that Boeing Dist/Dallas ordered 400pcs of V-Band clamps #670105 and there are still 188pcs on back order from Continental. And in this delivery they got 50pcs. Not sure how many AirPower got. Information from Packing Slip.

I use dishwasher soap, not much. It will work as a lube, and it will glide on way more easy!

On my 252/Encore SB engine my intake plenum boot is a little wrinkled, more than I think it should be. But what I can see I have full power 39" to 8000ft without problem. Will try to fix the attachment on the annual, since I think someone did some cowling work. Would be more easy when propeller is sent for overhaul.

I say go for it! I just recently bought an M20K 252 with an Plessy Gear Actuator (The one you can't repair) But the parts are out there, and now I managed to find a nice Eaton Gear Actuator fully working with less than 1300h and around 300h on the spring. Some parts may take time to find, but I order parts that will need in future just to not be grounded. So a little planning ahead is good and solve much.

Interesting... I got an invoice today too. When I ordered mine, I was 1 day late since they had in stock the day before, and it got sold when I placed my order. Wonder how many they get in each shipping since we both place on same date.

Good news! My V-Band Clamp was sent Tuesday, March 4, 2025 from Air Power. No confirmation e-mail or anything, I got a SMS from FedEx about a delivery and when I logged in and checked it says Shipped. I placed my order: October 8, 2024 I'll guess for you guys that are waiting, we now know they are shipping them out soon as they can.

I did buy the Donaldson, since it was already installed. Are there any differences between the two?

Mine is starting to get worn, and side (top) is nagged by some tool or something. Still holing up good, but it wrinkles quite much, will see if I can get at better fit. Think I bought the last one Mooney had in stock.

My idea is to remove probe at put it in water or heat it with something with reference termometer and see how my gauge reads.
