    Lubing the stabilator cable

    A smaller diameter pipe may keep it from wanting to tilt all over. The barrow pipe will slide down the cable shaft and keep it straight and lined up.

    Life Limited parts available

    Some door struts were a tad too long and would bottom out when you tried to close the door the last inch or so. The easy fix is to remove the ends with the ball and shorten them about 1/8" and on both ends. This took care of the problem. later on the company for the door struts offered shorter ends which took care of this. The smiley face is a crack on top of the engine usually. It comes from an older crankcase from the mid 2006 era and earlier. People have been warned over the decades not to over pitch their props, but owners and Mfg's did it anyway which at times caused this 2" crack on top of the thinner crankcase. After mid 2006 and later there was a new crankcase which was thicker. That said you are still warned not to over pitch your prop. I think I've said that once or twice.

    EGT question for the experts?

    CHT's are only on cylinder 2 & # and most of our EGT's are on the back cylinders 3 & 4. There are a few with all 4 EGT's, but not many. The EGT is a measure of the burn conditions within the cylinder and the CHT the cooling around the head (or the system itself). So this limits the question to cylinder #3. The answer is yes they can be different. From a loose CHT probe and bad EGT probe or a coolant issue. A reduced flow or using waterless coolant.

    EGT question for the experts?

    Header wrap doesn't affect your EGT reading. because the probe should be 100mm (3.9") out from the exhaust port (many aren't) the fire and heat coming out of there is fairly instant and consistent, header wrap has little to no influence at this stage. Header wrap was originally used by racers to keep the exhaust hot all the way down and out the exhaust pipes. This helped reduced colder gases from creating some back pressure. These guys did this to squeak out a couple more horsepower. For us our pipes are so short it isn't that kind of a benefit. We use it to keep all the hot radiated and convected heat off our hoses and wire insulation. You can test this theory yourself. Tester beware of the first test. Without header wrap would you run your engine and then grab your bare exhaust pipe. If you're this dumb please post the after test pictures of your hand. The second test is with header wrap in place repeat the test. You can not only touch the pipes, but gently grab them and within seconds can hold them.. A greatly reduced radiated heat affect. Because of the material the header wrap is made of and the millivolt use within the EGT over wrapping the EGT probe with the header wrap will cause EGT fluctuations as high as 120F. leaving a 1/4" space on each side is best.

    EGT question for the experts?

    The engine is leaner in the mid 4K's. It runs richer at high rpms to help stave off detonation. No problem here.

    The spacers do replace the spring, but there are some flat washers and another part that goes in at the top. FD USA would probably have those parts. I have never tried to ship any of these out of country. There is probably a duty on them.

    Lubing the stabilator cable

    You'll need a rag or something over the tube end to push on the tube. It takes some force.

    Max rpm or?

    Shoot for 5700-5750. If you see 5800+ then adjust the prop pitch a tad courser.

    Lubing the stabilator cable

    When we had to remove the spring years ago to put a long 2 part steel guide under the spring to keep it straight and from twisting in different angles we removed the spring and then squeezed it back down while out of the plane. You can do this in a vise. Then you put safety wire through it to keep it compressed until you get it back in place then cut the safety wire and release the tension. This spring is NOT a 98 lb. weakling. Call FD and have them send you the Safety Directive on the replacement of the CTSW spring guide that dates back to 2007. I looked and can't find the original. The original one had good pictures. I'm sure they have it and that will tell you how to do this. I had to do it to my plane and a few others and it wasn't that bad. I have learned that unless you really really need to get at something because it's broken some things are better left alone and better to get guidance on doing so first in which they usually tell you leave it alone unless it's broke.

    Stick Shake

    Normal for many. Now the first mystery is solved are we going back to the second stick shake? Is that flying left seat or right seat? p.s. You brought it up. LOL

    Throttle Lever Friction Adjustment

    You can't hurt anything. When you look in there it will be obvious. One bolt and nut. You can't get a wrench on the nut and that's why you use a flat tip screwdriver to hold it from turning while you tighten the only 13mm nut on the other end. After you do the first one you'll be able to do others with your eyes closed and singing, I've been working on the railroad. LOL Better brush up on the lyrics.

    Throttle Lever Friction Adjustment

    Wear and especially cold weather causes plastic to shrink just enough to be affected.

    Lubing the stabilator cable

    There are springs and a counter weight that may add what you think was drag. It's there to help relieve pressures when flying.

    Throttle Lever Friction Adjustment

    This is quite normal for cold weather. I had two in the last few weeks. Took me 10 minutes to tighten. It doesn't need a washer. I have adjusted tons of them over the decade. It's quick and easy. Take the 4 screws out of the throttle/choke plate. The plate will lift up. Down inside you'll see a 13mm nut on the right of the throttle and a bolt head on the left side of the choke lever. Take a smaller flat tip screwdriver and place it down between the bot head and the plastic block to keep it from turning. Take a 13mm open end wrench and give the 13mm nut a slight tightening turn. It only needs to be a fraction of an inch. Then check the throttle friction. If your happy with the friction you're done. If not tweak it a tad more.

    Mogas Octane

    I would stick with Decalin. TCP has harsher chemicals and is not supposed to be carried in the cockpit. Decalin is a better choice and a newer product compared to TCP. TCP can ruin your paint if not wiped up.

    Mogas Octane

    50.2 liters is 13.2 gallons. Whether you put in 1/4 oz of Decalin or the 1/2 oz Decalin is fine. Putting in the full 1/2 oz won't hurt a thing. Both the Decalin and auto fuel will help delete the leading affects of the 100LL.

    service life

    Same question and answer you got on the Rotax forum by Rob. The TCu and ECU do not have a service life-limit.As long as they pass the overhaul tests they go back into service.The ECU bench test is described in the 912iS or 915iS Heavy Maintenance Manual chapter 76-10-00The TCU bench test is described in the 912/914 Heavy Maintenance Manual chapter 76-00-00

    General stats from Garmin PIlot

    Ed, Being an analytical realist like I am I would ask this of myself. Why do you care about stats at this stage and all these years? You know where you fly, how you fly and how fast. What's it doing for you that you can't live without? Would it affect how, why , when and where you fly?

    Question on Matco nose wheel

    "I will go with my current procedure of: "tighten the axle nut to the point where it is takes up all axial movement but short of binding the bearings". I'm guessing this is what Matco intended?" Yes. The axle nut should be tight, but if you're cranking it down to the point of impairment then don't use the Godzilla torque. Bring it back to human torque. LOL The Marc wheels are a stamped flimsy wheel and will bend and have a different design.

    Question on Matco nose wheel

    The spacer is on the outside of the bearing against the fork. One on each side to center the wheel.

    No fuel crossfeed.

    Nothing's wrong. It even happens on some certified aircraft. It is a function of a flat fuel tank. Plus your instrument panel may not be perfectly square and the instrument may not be perfectly square in the mount. So when you think you are perfectly coordinated you aren't. So from now on fly 1/2 ball out to the right and the fuel will most likely stay equal. If you get real low like this again fly 1 ball out to the right and the fuel will feed the engine an d transfer to the right tank. It is a slow process so it isn't a fast process. It isn't something to seat over and most likely you can't fix it. Most of us have an imbalance in fuel drain we just compensate.

    Question on Matco nose wheel

    Do not put a spacer in. It is not needed or called for by Matco.

    Question on Matco nose wheel

    The Matco nose wheel has no spacer. Just tighten and go. The Marc front wheel does have a spacer due to its design.
  25. Here is a picture of the BRS 12 year rocket replacement kit. You build it from the ground up. You will need a vise and be able to read. Fairly easy, but if your mechanic can't get the plug gap right, set a prop pitch or know how to check the friction on the gearbox you may want to let someone else do it.
