  1. IMHP, I would not spend the cash to purchase and install a second 430W. Replace the old Nav/com with an SL30 and call it a day. If you really want another GPS then I would probably go for a 530w and let your existing 430w become the backup. The 530 is not going to be that much more than the 430 and the installation between the two is awash. At least with a 530 you will gain something Sent from my iPad using Tapatalk

    Exhaust and Intake Leaks

    This is the procedure recommended by Savvy for a fuel injected engine. I would think it should work for both but have never tried it in my C. Sent from my iPad using Tapatalk

    Exhaust and Intake Leaks

    Induction leak test This in-flight test is an effective method for detecting leaks in the engine's induction system. It is best accomplished in level cruise flight at about 5,000 feet MSL. It consists of a pair of tests: the high-MP test and the low-MP test. For the high-MP test, start with a relatively high power settingi - wide-open throttle for normally aspirated engines, or MP equal to outside ambient pressure for turbocharged engines - and full-rich mixture. Write down the EGT for each cylinder. For the low-MP test, reduce MP by about 10 inches and again write down the EGT for each cylinder. Disregard the absolute EGT values. Instead, calculate the change in EGT ("delta") for each cylinder between the high-MP and low-MP tests. Ideally, the amount of EGT change should be roughly the same for all cylinders. If one cylinder (or two adjacent cylinders) exhibit(s) significantly less change than the others, suspect an induction system leak affecting that cylinder (or those adjacent cylinders). Here's the principle behind this test: During the high-MP test, the induction manifold pressure is very close to outside ambient pressure, so any induction leak will have little or no effect on engine operation. During the low-MP test, the manifold pressure is significantly lower than outside ambient (by about 10 inches), so any induction leak will cause the affected cylinder (or cylinders) to run substantially leaner than the others, resulting in a smaller drop in EGT than the others.

    Might be interesting to do a GAMI test before and after repair of the induction leak. If the leak is significant it should show a much closer spread after the repair Sent from my iPad using Tapatalk

    Not exactly, your fuel injection or carburetor (don’t know what plane you fly) is trying to feed a correct mixture of air/fuel to each cylinder. You can adjust that air/fuel ratio using the mixture control in your plane. If you have an induction leak in a cylinder then that cylinder is getting a higher air/fuel ratio than your other cylinders; an overly lean mixture. In a fuel injected engine this will result in a lousy GAMI spread, badly tuned injection system, and you may not be able to run LOP. In a carbureted engine, which already have uneven fuel distribution by nature of the carburetor it will make fuel distribution even worse. Sent from my iPad using Tapatalk

    I would not want leaks in either induction or exhaust. Induction leaks will result in lean mixture for the affected cylinder. It will eventually develop into backfire or popping sound at idle settings like when you pull the throttle in short final. You will see a rapid EGT increase in that cylinder while leaning (or maybe not if you don’t have an engine monitor or it’s not cylinder #3). You will have an overly lean cylinder while running the others too rich. Not a very efficient way to run your engine. Sent from my iPad using Tapatalk
  8. Since my POH is all in mph I rather stick with that. Initially it bothered me, but now when a C or P driver asks me what she cruses at I say 165....... Sent from my iPad using Tapatalk
  9. The latest version of ForeFlight will give you an automatic terrain/obstacle warning no matter what page you are in. You have to set that in settings. Pretty cool actually. It popped up for me on a approach to an airport with a very tall antennae near by. Most folks with a C equipped with an engine monitor will tell you they have seen 435 more than once. 1400 hours on mine and I’ve only had an engine monitor for 6 of the 7 years I’ve owned her so I’m sure it’s seen plenty of 435’s and higher before that. That being said, if I climb at 120 I’ll be under 400 even in hot summer days and mostly under 380. Climbing at Vy will take you over 400 during the summer without a doubt on most Cs. Your situation was a bit different in that you were climbing with terrain nearby in IMC. Just make sure you are full rich and I would not worry about an occasional 435 hot climb. If it were that bad my engine would be in pieces and it is still performing strong. Sent from my iPhone using Tapatalk

    They’ve had two or three restaurants at Bartow go under. Too bad. I visit there quite often. Just not enough traffic I guess. Sent from my iPad using Tapatalk

    Do you know the exact temperature? And do you mean to say the climb was 10 minutes or were you red line for 10 minutes (hopefully not the latter) Sent from my iPad using Tapatalk

    Hope X39 stays open. I visit regularly as my son is going to USF and lives close to the airport. Sent from my iPad using Tapatalk

    My C was doing the same and it was an intake leak. Fixed the leak and popping went away. Sent from my iPad using Tapatalk

    That spark plug cover now has a half inch crack that has been stop drilled. Seven years ago my doghouse was a thing of beauty. No cracks whatsoever. Unfortunately they don’t stay that way for long. Sent from my iPad using Tapatalk

    Looks like they are a bit different. Here is a picture of mine taken a few years ago. The red arrow is the piece that is cracked both on the left and right hand side. The tab that goes down between the two rocker covers is completely cracked on both sides. Sent from my iPad using Tapatalk
