  1. Nickel Carbide Cylinders

    @CaptRJM, Who’s Ni plated cylinders did you use? I would like to use Ni cylinders when performing a TOH on my TSIO 360 SB. I did not think CMI offered Ni cylinders for the TSIO 360. Bill
  2. I replaced all 12 on my TSIO-360 with silicon gaskets . Done correctly as per the instructions it takes longer than you may think. I torqued them to 25 inch pounds in steps, ran the engine and checked the torque again. I spent all afternoon (4+ hours) You may want to check the condition of your rocker covers before you invest in new gaskets. Make sure the sealing surface is flat. The covers may be deformed, especially if they had silicon gaskets and someone over tightened them. I had to replace several of mine to eventually stop the oil seepage. Bill
  3. New to me M20K - many questions (now AOG)

    Check to see what type of CHT probe your JPI monitor uses for the #2 cylinder. It may be different. The factory or primary gauge is usually in the #2 cylinder and some JPI installations use an under the spark plug sensor as they cannot remove or replace the “primary” probe. The spark plug gasket sensors read significantly higher versus the probes in the other seven cylinders. I agree with what others have said about your fuel setup appearing to be on the lean side, but the problem may be also compounded by an inaccurate reading if that one cylinder has a different type of probe. I had an identical problem when I first purchased my K model. I replaced the spark plug gasket probe with the JPI probe that inserts underneath the factory bayonet. Search for 3/8” JPI CHT probe.

  4. My Encore was in the avionics shop for some work. After reading @donkaye & @Oscar Avalle posts and playing with 6.41 on my Ipad simulator, I quickly requested the shop to update my GTN 750. Tried it out today and it was great! My home base (L31) is in a black hole with no VASI or equivalent. This will not change anything during daylight, but will be a much appreciated additional tool at night. Bill
  5. Only one Whelen strobe not working

    That power supply is for the two wing tip strobes only. The tail is powered by another power supply mounted in the tail. It is mounted on an inspection cover on the left side. If I read correctly, you have already, determined the bulb is OK. You can swap the left wing, right wing outputs from the power supply and determine if it is internal to the power spply or in the wiring. You can also move the inop left side over to the unused output. I have attached Whelen's install manual. The Mooney service manual also contain some information on testing the power supply output with a volt meter. If memory serves correctly, a good power supply output is 400-600 VDC Use caution when handling the output wiring when the power supply is powered up. There is enough energy there to give you more than a mild tingle. Bill HDACF install.pdf
  6. Looking to Buy an Eagle or Early Ovation?

    I am biased, but think a 252 or Encore with Monroy tanks would suit you well. My Encore ( 105 gallons total useable ) flying between 15 & 20 K feet should be able to make that 1000 mile hop on 75 to 80 gallons in no wind. There are several very knowledgeable K model owners on this forum. @kortopates @gsxrpilot @Parker_Woodruff @jlunseth and others. They should have some real world examples. Bill
  7. Is there a 200 kts Mooney?

    The Aspen has a VSI tape that pops up in the HSI window when you are in a decent. 200k TAS is plausible in a 252 @ 25k ft. I think he is level flight. @gsxrpilot, Have you ever looked into why the JPI and Aspen OAT indications don't correlate closer. If the Aspen is reading low you are going a knot faster. Bill
  8. I like the Bogi-bar from Bogert Aviation. It locks solidly onto the axle of the tail wheel. I have used and owned others, but believe the Bogi-bar clamps on the best if properly sized for your particular tail wheel. Generally I only pull with a tow bar and push with my hands. I typically push most tail wheels at the attachment point on the rudder for the flying wires. Place the base of your thumbs on the attachment point and you can push without pushing on the wires or fabric surfaces. Bill
  9. Prepping for Harvey

    Don't need to jack it up. Pull the airplane forward, lay out garbage bags behind the wheels and push it back on to the bags. Then pull them up. This is from experience as I used to reside in a crappy row of T hangars that were susceptible to minor flooding. Bill
  10. Oil in Standby Vacuum Pump???

    If I did it again, 3 to 4 hrs. Doing it for the first time 4+ hrs. Probably the most difficult part was removing the old hose from the manifold under the glare shield. It is difficult to reach and see. Practice on the spring clamp with your tool of choice on the standby vacuum pump end before tackling the hard to get to one. Remove the left rear seat back and screws holding the side panel so it can pulled away at its top and back edge. Remove the carpeted side panel in the baggage compartment. It comes out easy with the side panel loose. From that point I could kneel in the baggage area and reach and see the two difficult spots when pulling the new hose in place. There is a vertical piece of the fuselage tube frame located at the end of the passenger compartment and beginning of the baggage area. The hose is routed between that piece of tubing and fuselage skin which is a tight fit. The other tricky spot is just forward of that area. The hose transitions down and forward through a hole in a flange of the fuselage. As I feed the new hose through that hole, my helper pulled on the old hose over the top of the panel. That is a long pull, but we did not encounter any resistance from that point forward. Bill
  11. Oil in Standby Vacuum Pump???

    After determining the degrading Tygon tubing in my standby vacuum system was the problem, I replaced it with Aeroquip 306 (MIL-H-5593) due to concerns of damaging another vacuum pump. Now I am really glad that I did. The old tubing showed evidence of its oil or plasticiser attacking other plastic pieces that it was in contact with. Surely the long term effects of being in contact with wiring insulation would not be healthy. See the attached photo with the imprint of a tyrap on the Tygon hose. I have learned a lot since my first post. IMHO, Tygon tubing in this service should be inspected on a regular basis and replaced at the first sign of degradation. The replacement wasn't as difficult as I originally thought. I removed the pilot's seat , glare shield, baggage compartment side panel, and all the lower side panels. I joined the hoses together with a short piece of 1/2" wood dowel and a couple of screws. Pulled the old hose from the front and feed the new hose in from the rear. Snaking the new hose in place was the easiest part of the job. I spent more time removing and installing panels. If I had to do it again, the pilot's seat and lower side panels would stay in place. The two tricky spots for snaking the hose in place can be accessed from the baggage area. Bill
  12. Oil in Standby Vacuum Pump???

    Have you removed the glare shield on top of your panel? Access to where it connected to the manifold was from the top on my K model. It is behind the attitude indicator on the fire wall. I was tempted to remove the AI for better visibility but managed without doing so. Bill
  13. Lycoming factory lead times for overhaul?

    I purchased a factory reman from Lycoming in Nov '14. The actual delivery time was 11 weeks vs the 6 weeks quoted. Based on the date on the test run sheet, the engine was assembled in 4 weeks. Apparently it took another 6 weeks for them to paint and prepare it for shipping. Bill
  14. Optimizing 201 engine performance

    What position are you flaps in? The flap toggle switch in your photo looks like it is in the take off position. Bill
  15. Oil in Standby Vacuum Pump???

    Mark89114 Based on the N# your O is a 2000 model. Is the tubing to the vacuum pump similar in appearance? Bill
