    M20C Cabin Water Leak

    No, not detached. That is the gap between the fuselage and the wing. IT is under the fairing and sealed with duct tape. I told my wife I had to duct tape the wing back on after a maintenance project; who's ready to go for a flight?

    M20C Cabin Water Leak

    Check the duct tape seal between the wing and the fuselage. there's a good chance that has deteriorated and water is running down the wing it into the cabin. Sent from my Pixel 2 XL using Tapatalk

    Fuel leak?

    That's a lot of gas to be losing in 2 weeks without evidence of a leak! . Mine has sat for a month before and not lost a drop. I think I would go with the theory that somebody stealing your gas. Do you keep your tanks full? I have had it piss out of the fuel vent before. But 10 gallons? I will be anxious to hear the outcome of this! Good luck with the sleuthing!

    I need to sit in an M20F

    I have a '75F at C77, but it will probably be going to a new owner in a couple weeks. Sent from my XT1585 using Tapatalk

    This is why I fly an electric gear airplane! Sorry, just had to take a poke at the J-bar guys. [emoji4] Sent from my XT1585 using Tapatalk

    Not the same angle but... Before: After: They are slightly less than an inch larger in diameter.
  11. It's been a long and sometimes frustrating road, but today success was achieved! As most of you that have followed this project know, there was an unacceptable increase in CHT to go along with the very acceptable 4-6kt gain in airspeed. We tried many things to decrease CHT, most of which was only marginally successful. The decision was made to open the inlets to add more air and, after today's test flight, there was a solid 20 degree drop and the CHT numbers are what was being targeted! I personally think the larger inlets look better. Hard climb (Vx) yielded a high number of 367. Cruise numbers leveled out around 357. This was achieved at 50ROP, WOT; much leaner than I usually run it ROP. Oil temp was a solid 190. OAT 22 in the climb and 17 in cruise. On a really hot day, I am expecting to see no more than 380 on a climb and 365 in cruise. I couldn't be happier these numbers! Some rough calculations don't indicate any loss of airspeed with the larger openings. I will do a four-way test when I can though. The next thing to do is removing the third cowl flap and see what kind of difference it makes... if any... in both speed and cooling. The furry kids went along for the test flight

    Erratic idle... SOLVED!!

    You're welcome. I have learned so much from the free flow of information on this site and other sources. I always try and pass on anything I learn. I believe the information flow has lowered my cost of ownership considerably.

    Erratic idle... SOLVED!!

    When the plane was hot (after a flight), it would idle kind of like a big-block Chevy with a performance cam installed. In other words, it would run smooth for a bit, then quit for a split second then catch. Rinse and repeat about every five to ten seconds or so. During this time, there would be an occasional back-fire through the exhaust as well. I had heard the same thing about boiling the fuel in the lines to the injectors and was ready to accept that as the reason, but I couldn't make that reconcile with what I was seeing. The fact it was only happening when the engine was hot, made it that much more frustrating. After a hot-start, I DO believe that is the reason for the rough running, but it should smooth out very shortly after start. Had I not attended the Lycoming induction seminar at KOSH, I would have NEVER figured this out! There was no visual indication of a leak anywhere. The premise of the seminar was people go right to the fuel servo as the cause of rough idle problems, but the servo is almost never the problem and many people end up overhauling a perfectly good servo. Not that it can't be the problem, but it rarely is, according to the Lycoming rep. Strange thing was, that was not the seminar I was supposed to attend; it was a mistake in the schedule printing. Everything happens for a reason. I don't have pictures, but it was an easy job. Pull the inlet side fitting from the mechanical fuel pump and match the o-ring. I am very blessed to have an engine shop on the field with good parts availability. Before going to the trouble of doing this, I would run the clear tube from the servo to the spider and see if there are any bubbles. I only went right to the fitting because of his story of a Mooney doing the exact same thing as mine.
  14. I have been dealing with an erratic idle for a long time now. Nothing seems to help. It would only do it when the engine was hot. There are no intake leaks so I have really been stumped. At Oshkosh this year, I visited the Lycoming tent. They had a seminar on sticky valves, but that particular one got cancelled or rather rescheduled, and the one I sat in on was about induction systems. I wasn't going to stick around, but I thought well, this might be interesting. And it was! One of the things he talked about, was people pulling their fuel Servo and send in for overhaul when it is unnecessary do to idling issues. Not that it can't be the problem, but it rarely is. He said to run a clear tube from the fuel Servo to the spider and watch for bubbles. If there are bubbles, then you have a airframe-side fuel leak. I was all set to do this when I got back from Oshkosh but then he said something else that caught my attention. He said they had Mooney come into the shop with an erratic idle problem but only when it was hot. after 3 weeks of diagnosis, they finally found that the intake side of the fuel pump had an O-ring that had to run up on the threads and when it got hot, created a small leak. I thought to myself, "I have a Mooney that has an erratic idle when hot. Upon his advice, I pulled the connection to the inlet side of the fuel pump and replaced the O ring that had been smashed and had a ridden up on the threads. With the new o-ring in place, no more erratic idle! I can't even explain the joy of fixing this! It has been a huge pain in my butt for a few years now. if you're having a problem with an erratic idle, and you have no intake leaks, take a very close look at the airframe side of your fuel system. the chances are very good you have a leak there somewhere and it most likely will not show blue staining since it's on the vacuum side.

    Will the engine run on water? Almost found out!

    Airplane sat on the ramp in a torrential downpour last week. There was exactly zero water in the tanks. I am positive now the water came from the truck. They had a different place they were fueling the truck and there was a problem with the first place so I am now convinced that's where the water came from. Stay vigilant guys and gals! I have been getting fuel from this, well-known, brand name FBO for 4 years and never had a problem. It only takes once. Sent from my XT1585 using Tapatalk
