I lean my C aggressively enough that I needto enrichen to taxi uphill . . . Almost never foul plugs. When I do, it's 2000 RPM, leaned less than at cruise, for 60 seconds. Oil change time is good for checking / cleaning plugs.

Oil change advice _ which oil and filter?
Hank replied to Lukon's topic in Vintage Mooneys (pre-J models)
For what it's worth, I've been using AeroShell 15W50 and Champion filters since I bought the Mooney with a wet PPL eleven years ago. That's also what the previous owner used. Our A&P had a huge stack of AeroShell, both 100W and 15W50, and shelves full of Champion filters. Never saw less tha 10 cases of each oil stacked up in the corner. -
Oh oh, Nico--sounds like the smoke got out! That's what makes electronics work . . . . Wish I could advise on the repair, but if the electrolyte has run over other components, they may no longer work, either. I fix lots of things, but always replace "black boxes," since they seem to run on magic and smoke . . . . .

Which cylinder to watch when leaning?
Hank replied to Lukon's topic in Vintage Mooneys (pre-J models)
@Lukon, something changed between your C and mine; my red line on the tach is 2000-2250. Just experiment within the limits of your Performance Charts and fund what works for you. The formula MP + ALT = 46 should be fine. -
How much was the Handling Charge from the FBO? I've also arrived with everything closed, parked myself, tied myself down, used my own chocks. Leaving in the morning, I vehemently protested the handling charge, as my plane was still where and as I had left it the night before, with no help and no handling . . . .

No fee to land, just to park.

Much mode often, FBO policies towards pilots drive us away from the field and away from the restaurant . . . . Yes, I've been charged $25 ramp fee for stopping to eat. Never went back . . . .

Prepping for owner assist annual. Check my list?
Hank replied to ragedracer1977's topic in General Mooney Talk
Get a supply of small ziploc bags and a marker. I pull inspection plates and bag the screws in groups--Left wing, Right wing, tail, spinner, doghouse . . . . Bunch of spare screws (measure each one when they come out, you'll be ready for next year) Baby powder for your new tubes Graphite antiseize for spark plugs Can of contact cleaner Plenty of rags Your favorite belly cleaner (I like Wash n Wax) Can of TriFlow My job is always to remove all inspection panels before the IA gets there. I pull the plugs and clean them while he's checking compression, then reinstall. I always wash and wax (now in one quick step) the belly while it's off. Check what grease is in your prop, and get some of that for next year. There's a sticker on mine under the spinner, it's probably either #5 or #6. I'll probably think of more later. Torque wrench for reinstalling plugs (mine came from Harbor Freight) Something heavy to hold the tail down while on jacks Spark plug socket--I tried several, then bought one from Spruce Various hand tools--screwdrivers (regular & phillips), pliers, needle nose, Standard wrenches, ice pick or similar (for aligning panel screwholes) Creeper Nearby place for lunch -
Which cylinder to watch when leaning?
Hank replied to Lukon's topic in Vintage Mooneys (pre-J models)
Ahhh, leaning a carbureted engine. Forget everytbing above except the definitions of "peak." We have no injectors, therefore no GAMI spread between cylinders. All mixing of fuel and air, and distribution to the cylinders, happens right there in the carb and is pretty much not adjustable. Climb full throttle, full RPM and full rich. Level off and let the plane accelerate. I generally don't do anything until my C is indicating >130 mph above ~6000 msl, or above 140 or so below that. Then I set the throttle an inch below where I want it, and reduce RPM (which makes Manifold Pressure rise). Use the Performance Charts in your Owners Manual for this. I used to use anything outside the Tach's redline as long as the numbers on Manifold Pressure gage and Tach added up to 46 or less. Now I've pretty much settled on three power settings by altitude: Low level (< ~3500 msl): 23" / 2300 Mid-level (> ~3500 -- 7000 msl): 22" / 2400 High cruise (7500 msl and up ): WOT- / 2500 Once power is set, then lean the mixture. As mixture leans out, the plane will accelerate. Watch EGT, it will rise; when it stops rising, yiu are at peak. With plent nof altitude (8000 msl or so), you can cruise at peak, but I rarely do. It's difficult to make a carbed engine run smoothly Lean of Peak, but you can try the following tricks: Reduce throttle slightly (I pull it back enough to make the MP needle just start to move = Wide Open Throttle minus [WOT-]). This will cock the throttle plate in the throat of the carb and hopefully create some turbulence there for better atomization of the fuel and better mixing with the air. Crack the carb heat open a little bit. Experiment to see how much to use, and if it helps. Gently ease the mixture back so that it is leaner than peak. If your engine continues to run smoothly, you can cruise there. Check for loss of airspeed; I lose more speed than the injected models when even slightly LOP. If your engine is rough, push mixture forward and run ROP. (This is what I do.) Work with your A&P if your engine is rough when slightly LOP. Look for induction leaks, lead balls in your spark plugs, etc. I was finally able to run smoothly LOP after rebuilding my carb heat box, but even then only to about 20-25° LOP. Flying this way, 50° ROP (the thought of which bothers many people here), WOT- / 2500, I can confidently cruise 4-1/2 to 5 hours with an hour's reserve. When flying, learn to think of your range in hours, not in miles, as the distance you can cover is affected by the wind during your flight. Leaned at altitude in level cruise, indicating over 140 mph, my groundspeed has been as high as 186 knots and as low as 68 knots . . . . My wife and I have flown 4:45 twice, and both times I had 11-12 gallons left out of the 52 I started with for 8.4 gph average. One of those was 3 legs: home from Mooney Summit (an hour), short flight for fuel (~20 minutes) but pump wouldn't work, then off on my 3-1/2 hour trip to furthest WV. Congratulations, welcome aboard Lukon and fly safe! Hope to meet you sometime; where are you based? -
Removing rear seat backs, 1969 M20F
Hank replied to chrixxer's topic in Vintage Mooneys (pre-J models)
When I removed and put back the seats in my C, it was some of all of those! -
I used to give rides on Airport Day with several 172z and a Cherokee 180. I'd pull back to less than 20" / 2300 and keep reducing throttle to not run over them (16"? 17"?). It worked well when I paid close attention to power settings the first flight or two, then used it the rest of the day.
-
Could you see anything before that? Or tell position of the flight controls?

Often the big city FBOs publish overnight parking rates and fuel prices, sometimes with a note of "one night free with XX gallons purchased." Then when I stay overnight, there are four additional fees on the bill . . . . Or I drop in for lunch, stay an hour and a half and am asked for the full overnight fee and a handling fee. This type of treatment makes pilots not go back to eat, and often leads to closure of on-field restaurants due to loss of fly-in business. Maybe we should all call the businesses we visited, and tell them that the FBO added $25.00 to our lunch bill, so we will not be coming back again. Then the business could pressure the FBO directly (along with face-to-face pilot complaints) and the airport manager. When paying that $20 parking fee and the $5 handling fee for them to do no handling and only provide a walkway from the ramp to the sidewalk, I always comment negatively and when in a bad mood, vigorously, with comments about never coming back. If only there was a way to spread the word, somewhere to post a true comment that wouldn't get taken down, leaving only the positive ones behind . . . .

Raise the nose, push full rudder to the left for extra working space on the right pedal. Reverse for the left one.

He makes a lot more than 3 posts every two days. Maybe you meant October 30?

Looks like fun!
-
Ask @Wildhorsesracing . . . . I think it looks pretty good!
-
I bolded the easy to do parts that will save money and headaches. Can't comment on LOP, as your injected engine does that much different [and easier!] than my carbureted one . . . Have fun, learn lots and fly safe!

Jerry was my PPP instructor when I first bought my Mooney. I hit 100 hrs Total Time enroute to the clinic; I still use much of what he taught me when I fly.

Click on his avatar. They are on all of our pages . . . Anything to make an anthony-styled bulleted list! Yes, "anthony" not capitalized on purpose. Or should I have used "-a" instead?

Hmmm, here are Anthony's current stats: 19,925 posts 5,566 reputation points 90 days won Joined 13 June '09 Last visited 11 hours ago [just changed from 10 hours ago], so last visit at 0130 CST / 0230 EST. from memory, he is on almost every day early mornings, before my 0500 CST breakfast mid-afternoon evenings nights after I go to bed He is listed as "Non-Stop reader/writer" My guess is that he will hit the magic 20,000 posts on Saturday, maybe late Friday night but in the early hours of Saturday morning. Not a psychiatrist, just an engineer . . . .

Because it's low enough power to avoid the Red Box, but still enough to make good speed. Search and find the chart . . . Should be in one or more of the referenced Pelican articles. DO NOT search MooneySpace for LOP, unless you have hours to kill!! SECOND on the MAPA PPP. The sooner you go, the less bad habits you will have to unlearn. They will teach you how to manage your engine properly, what speeds to use when. My first was a mere 5 weeks after I finished my insurance dual, and I'm still flying like they taught and applying the lessons learned. See www.mooneypilots.com for details.

When my dad retired, he left frigid North Georgia in early February and drove south until he had to turn on the AC in his truck. Stayed in Frostproof, Florida for about 10 years . . .
