      Bill: Thanks for the info. I like  the tie downs, and intedn to purchase them.
      For installation I will use
      nut plates, and no. 8 screws.  Since these will be on tha flange of one of the
      floor ribs, is not too hard
      to use the Squeezer, to set the nut plates...
      
      On a matter of where to place the fuel meassurement  tube, wheat I did, is on the
      side of the fuselage,
      on each side, took a piece of aluminum, to cover the space between the two longerons
      on the bagage compartment,
      they are about 10" by 8" or so, covered these with cloth, to match the interior,
      and use screws with dimple 
      wahsers.  so now I have on the bagagge compartment  two pockets, one each side,
      to store, things I have
      the Airpot book, theFlight guide, flash lite, and documents, on the other side
      I keep the fuel measurement stick
      I made, and the plastic tube to drain fuel for testing...
      
      I hope this will give you another idea..also.

      Bert,
      
      FYI - the tiedown bases are already chamfered for a #10 screw, thus you might want
      to upsize your platenuts.  I was afraid #8's would pull through.
      
      Had I thought of this while building, like you there would be plate nuts back there
      rather than rivnuts.  Oh well, live and learn.
      
      Thanks for the tip on the fuel cup.
      
      Bill

| Subject:  | Electronic ignition question | 
      
      Ok, guys - questions.  Let's see if I can express this clearly while
      starting to chomp-down a frozen margarita...
      I've got dual Pmags, model 112's, on my Lyc.  Basically no trouble out of
      them for 100's of hours, except I removed and disabled the MP vacuum lines
      when one Pmag developed an internal vacuum sensor leak that was playing
      havoc with my manifold pressure readings... I knew an eventual upgrade to a
      newer Pmag model was in the cards when that happened, but have been putting
      it off.  Recently replaced the plugs.  Old ones looked really good, but I'm
      just anal about cheap & easy maintenance items like that.
      
      Last flight, I noticed a significant discrepancy in mag drops at run-up:
      about 50 rpm on the right side, but 160 running on the left.  Flew okay
      around the patch that day , but it got me to worrying a bit.  Today, run-up
      performance was the same as the last time - big drop with the right side
      off.  Still, I wanted to get some engine monitor number in flight to see
      what might be up.
      
      When I shut off the left mag in level cruise, the rpm dropped slightly, and
      EGT's rose slightly on cyl's1& 2 (I can only read two at a time with my
      ancient EIS).  When I shut off the right ignition, the EGT's again climbed,
      but the #2 went to redline immediately (and I mean fast, from  1510 to over
      1600F) and the engine rpm drop was more pronounced.  I repeated the test
      with the mixture full rich, and even though i was starting with EGT's in the
      1380 range, the #2 went over 1600 again, just a little more slowly.  In the
      seriousness of the moment, I never bothered to check cylinders 3&4; don't
      want a burnt valve or holed piston.
      
      Realizing i had a situation that could damage the engine if I lost that
      right ignition in flight, I called it a day and decided it was a
      safety-of-flight issue that justified pulling the mags for replacement right
      away. Unfortunately, the Emagair folks are taking the slow boat home from
      Lakeland, and it will be Friday before anyone can return my calls.  (Hey - I
      type okay when nursing a bit of tequila, eh?)
      
      So here's the question: what's causing this behavior?  I was expexting a
      lower EGT on one cylinder if it was not firing right, unless the timing has
      jumped.  I can see how a very advanced timing on the left mag might shoot
      the EGT high,but why not on all cylinders?  ANd if advanced timing is the
      cause, why not showing up when both ignitions are on?  The right side would
      be firing too late to help things.  I guess it must be retarded timing if
      anything, but I never knew that problem would drive the EGT up. A plug or
      wiring problem on cylinder 2 would make the cylinder run cold, not hot,
      would it not?  I'm just really not sure what is going on here, but I am sure
      hoping a replacement of the mags with the latest, greatest model will fix it
      all.  Even if resetting the timing on the left mag would fix the issue, I
      still am gong to pony up for the new mags, so I might as well take my
      down-time like a man and do what common sendse tells me need s to be done.
      
      I would like to here what the hive mind thingks is up wityh my airplane .
       I don't liek not being able to fly for a coiupel of weeks.Now that I've
      have finished the margarita, the problem really doens't seem that serious.
       Thanks fro letting me get that offf my chest.  Irt's getting dark but it's
      such a quite evening and the winds are calm.  Screw it, I'm going flying
      whwther the P-mags coperate or not.
      
      Shtormy
      
      point me to th hangar, Mabel

      That sounds reasonable.  Stormy, now might be a good time to trade them in
      for the new 114 P-mags.

      I've got dual Pmags, model 112's, on my Lyc.  Basically no trouble out of

      when one Pmag developed an internal vacuum sensor leak that was playing

      just anal about cheap & easy maintenance items like that.
      
      
      Last flight, I noticed a significant discrepancy in mag drops at run-up:
      about 50 rpm on the right side, but 160 running on the left.  Flew okay
      around the patch that day , but it got me to worrying a bit.  Today, run-up
      performance was the same as the last time - big drop with the right side

      what might be up.  
      
      
      When I shut off the left mag in level cruise, the rpm dropped slightly, and
      EGT's rose slightly on cyl's1& 2 (I can only read two at a time with my
      ancient EIS).  When I shut off the right ignition, the EGT's again climbed,
      but the #2 went to redline immediately (and I mean fast, from  1510 to over

      Don't know much about p/e mags, but late timing will drive cht down & 
      egt up. Fuel is burning in the exhaust pipe instead of in the cylinder.

      Okay, I'll check the plugs and wiring first. I'd hate to install new mags
      and still have the same issues.  But the 114's are on my immediate do-list
      anyhow.

      It was a smallish margarita, actually.  Just playin' with you guys.
