Called my 63C back in the Day "Baby", My 84K is called the "Mistress" by my current Wife.

Is your engine driven fuel pump set to the proper settings that are required for the intercooler? When my pump was starting to go out, I was always chasing the manifold pressure, (did not know it was going south). When it finally went belly up and I put a rebuilt pump in and my A/P set the proper flows it was a whole new plane. Many mechanics will set the pump to stock settings not knowing that they are different with intercooler and Merlyn. Pritch

From a flight a couple of months ago. #5 is the hottest and #3 is the stock probe. #6 is a new cylinder and is the coldest. Pritch

Here is the letter @carusoam scanroy.pdf

I have a letter dated June 22 1984 to Mooney 231 owners from Leroy Lopresti. "For a short field takeoff, I put in the cowl flaps in trail, or when I'm really pinched, close them for the takeoff run; they make a significant difference in the airplane's rate of climb. Be sure to open them again as soon as you have cleared whatever obstacle are in your path." Interesting papers one finds in the collection of files that comes with the airplane. Pritch

So here is a question to you 231 pilots. Would you ever take off with the barn door Cowl flaps fully closed in order to have better performance on a shorter runway? Pritch

Hope you guys and gals have fun. And stay out of the smoke. Pritch

Once you have the velco unhooked tilt the seat forward or backward and just pull it up. Pull the seat bottom out and let the carpeted part out of the seatback lay flush. Pritch

Same with one that I went to look at in the Denver area in 2015, picture looked great but when I got there the left tank was empty and a blue stain on the ground and bottom of the wing. The fellow who bought it also found a major electrical problem and had to tear out the panel. I ended up finding mine in SAC that was owned by a hand surgeon that was well maintained. Pritch

I have a spare Red an Green lens if anyone needs them. Pritch

I don't think you drink, but when you do, you always drink the good stuff Pritch PS Keep it up you always have something good to say

But that 6 cylinder cowling makes it look so darn SEXY. I can get 160Kts at 10,000 while burning 9.1 gph, but the deciding factor for me would be if it was a GB and not the better LB engine. Pritch

Could be the clutch on you Alternator, mine was doing something similar. Pritch

In and out done almost 2 years ago, wouldn't fly without it. Pritch

here is one of my favorites, recharge with USB. Sometimes on sale at Andrew/Amanda.com for $42

The test show that the Alt was good, so next easiest to do is replace the reg. (lot easier that pulling the Alt. which is buried on the back of the case). Next you have to pull the Alt off to check the coupler. So if you are paying an I/A to pull it a $110 an hour and at least 4 hours to R&R, one starts the easy way. Fortunately the I/A know my capabilities and allows me to do most of the work under his watchful eye. Pritch

Charging system quit working last week so off to the Maintenance Hangar to check it out. With the initial testing it showed that the voltage regulator was not functioning properly. Ordered new reg. and installed, test flight, a little better but still not right, the only time I got 14 volts was on short final with next to no rpm's. I/A said to pull the alternator, now this is a TSIO360 Continental so the Alt is mounted on the back of the case between the Mags. 2.5 hours later I have the Alt. off and back to the I/A to have him look at it. One quick spin of the gear and he confirms that it is the coupler that has gone bad. Two days and .9AMU's later I am reinstalling the Alt., another 2.5 hours of close quarters work. Quick engine run up and everything is POSITIVE for charging. Worse part is I had just put a new Alt. on two years ago, but used the old couple as it is more expensive than the Alt. Good thing I am retired and have the time to tinker on the Mistress. Pritch

Here is a leisurely flight from KSAC to KRDD, with a slight headwind, a couple of weeks ago. Pritch

Critical Alt is 19,000, if equipped with intercooler and Merlyn waste gate. The 231's top alt is 24,000. Later models are equipped with O2. Speed and fuel flow depends upon whether you fly LOP or ROP.

That sheet metal is so shiny that it looks like you have @M20Doc 8 cylinder engine on the stand. Pritch

Sheep skin, it's what every dog wants. Pritch

Take the old one into your local Napa Aviation parts store and get one for a couple of bucks. It is nothing special. Pritch

Not the 900, just an 830 but is spot on for fuel flows. Coming home from Sacramento the other day, said she burned 16 gal. and went to the fuel pump and could only put in 16. Install was $0.00 as I did it myself under the watchful eye of my I/A. It is really an easy install. Pritch
