Keith & Janace Harbour --------------Boundary-00=_I3D34961VA4000000000 Yak-List message posted by: "A. Dennis Savarese" There are two temperature probes on the M14. Both are typically attached to the rear spark plug on #4 cylinder. Check the temperature probe connections inside the wiring harness and the connections inside the cannon type plug at the back of the instrument.

My M14PF runs nice and cool - CHTs around 170C (Su26, shutters removed) even during hard acro at full power with timing set at 14deg on the prop flange. I have recently re-timed it to 16.5 deg and my CHTs went up by 20C. My mag drops also went from 1.5 to 2%. She is going back to 14deg today. Jerzy Strzyz ________________________________ Message 4 _____________________________________ Time: 01:03:41 PM PST US From: "A. Dennis Savarese" Subject: Re: Yak-List: High cylinder head temp. --> Yak-List message posted by: "A. Dennis Savarese" You must have M9F mags on your PF if you're setting the timing to 14.5 degrees BTDC. Most PF's now come with M9-35's, which are timed to 4-6 degrees (depends on the number stamped in the boss of the mag under the mag cover) AFTER TDC. With the M9F's, an increased # of degrees = more horsepower. More horsepower = more heat. 190 C at full power during hard acro is VERY acceptable.

The bubble will compress and transfer the same pressure to the gauge as the fluid. Changing a hose of any kind introduces the possibility of a blockage in the line or fitting. A new hose should be pressure tested and then blown out with air BOTH ways to be sure the fitting did not cut the hose and cause a rubber flapper valve to be created inside the hose .

A newbie who has no interest in formation, or aerobatics, or flying his airplane is a bit limited in his choices, but we do encourage *especially* those new to the community and their airplane to attend. Nowhere else will you find such a wealth of information regarding the safe operation of your aircraft as you will at All Red Star. Over 50 pilots, most of the veterans of their mounts, not to mention a gajillion hours of combined military, airline, and other professional type flying time experience to draw on. Most, if not all, are happy to share their experience with the newer pilots...heck, it's in everybody's best interest to help the community, right? Also, consider the following experts donating their time to the event: * Vladimir Yastremski and Bill Blackwell are there giving help and seminars on engine and airframe maintenance. * Jim Fackler is giving a prop balancing, shaft vibration analysis seminar. * Highly renowned aviation photog Tyson Rininger (Sean Tucker's personal photographer) will be giving a briefing on air-to-air photography safety. * Allen Silver doing his emergency egress and parachute maintenance seminar. plus *The only aerial demonstrations event of everything from a Yak-18T to a MiG-21 in the west. *Camaraderie with the most enjoyable warbird community on the planet (and I mean that! No patronizing here...). And don't forget that the prices you see for the event are "all inclusive." The only thing you need extra money for is gas (yeah, that's been cheaper...), merchandise, and booze. Heck, we're even including the keg beer this year. I've looked long and hard for another aviation event where you have this much fun with a great group of people for anything close to what we charge...I'm still lookin'. And after all, that's the whole point of ARS! Hope you can make it out some day, Walt. I simply cannot do it justice in writing....
