				Hi all
 
 I'm having problems starting my Yak-52. Symptoms:
 - I can get a normal start, but only if the air pressure is right up over 5 (ie 50). Once the prop is turning, she starts easily.
 - Anywhere much below 5, no start.
 - If I press the start button, no prop movement at all. Not even a twitch. Just a soft whining sound that does not sound much like air rushing through.
 - Using the little override lever at the side of the valve produces the same result, ie no movement.
 - Battery voltages are good, and we get the same behavior using a 28V external power cart.
 
 I suspect that the valve itself has a lot of gunk in it, and that at high pressure the air can make it past the muck. But I'm no expert.
 
 Does anyone have any ideas? Should I be looking to replace the solenoid?
 
 Thanks
 Mike

				Some feedback on the starting problem:
 We eventually replaced the solenoid valve, and the starting improved. Still not as good as I'd like it, but on most days I can get a start without having to drag the scuba cylinder out.

				For both the Yak and the CJ, the pneumatic system is one of the most important aspects, but almost continuously problematic. Over the years, I ended up replacing every check and shuttle value and pretty much all of the tubing before a long list of constantly appearing problems finally disappeared. Replaced the starter solenoid valve early in the game. Just comes with the territory. Here are some thoughts after years of work one the pneumatic system of my CJ.
 
   •  Use the highest quality tubing you can find. Avoid inexpensive, thin wall bargains. 
   •  New B-nuts and collars from Doug Sapp is the way to go. 
   •  Flaring tool that compresses the base of the flare rather than stretches it. Avoids creating a failure point. 
   •  Secure the tubing with Adel clamps. Vibration is the most common cause of failure. 
   •  Replace/rebuild the check/shuttle values at regular intervals. Corrosion is insidious. 
   •  Don’t forget to service the air/water separator twice a year.
   •  Lubricate the system with 50-50 mixture of 98% alcohol and glycerine every 3-4 months if you fly on a regular basis. 
   •  Get/borrow an ultrasonic leak detector. Will uncover much more than is obvious. 
   •  Replace old rubber/cloth actuator and brake lines. They do not age well. 
   •  Bypass everything in the aft cockpit. Not needed and just another source of potential leaks. 
   •  Replace the main and emergency air tanks with new from Doug Sapp. Close to failure-proof. 
 
 Do not get frustrated when some part of the pneumatic system fails. This is what we signed up for when purchasing these airplanes. Just fix it and move on. However, over time be proactive and plan to replace prior to failure the oldest parts, even if they are working. It’s not really if they will fail but rather when it will happen. To my way of thinking, it’s easiest to do this beforehand.

				Thanks Warren. Superb list. Where can I locate a flaring tool that compresses rather than stretches? I have a cheapo one of the latter variety that I've never liked. 
 
 Also, my recollection is that Doug Sapp recommends cod liver oil to lubricate the system. I gather though that you've had success with the alcohol/glycerine formula over the years.

				Agree with all.  Been there done that, proudly wear the T-shirt.  
 
 I would add.  Talk to Doug about his final filter design made from check valves.  
 I have those in my plane.   Cured dirty tubing etc.  Love Doug’s final filter.

				Byron,
 Next time I go to the hangar I’ll take a picture of the flaring tool. Rather than the ¼ inch aluminum line that’s commonly used, I use 6 mm tubing and the flaring tool is metric. 6 mm tubing is often used in foreign automotive brake system applications. Lots of different vendors. This is also available in stainless steel, which is harder to work and flare, but far more durable. 
 
 As any experienced A&P will tell you, properly flaring the end of a tube is something of an art. There are many details that make the difference between creating something long-lasting and something that temporarily gets you by. Also, flaring is only a part of the overall exercise. If the nipple is bunged up, a perfect flare will leak. And if the B-nut is under or over tightened, the connection will not work or last as advertised. My experience has been that most of the fail points in a pneumatic system are the result of something preventable. 
 
 I’ve heard of many approaches to servicing the system: WD40, cod liver oil, compressor oil and glycerine. Glycerine is what I’ve always used and it seems to work well. This is easily ordered on Amazon as “Glycerol Glycerin.” 30 ml of reagent grade glycerine for about $6.

  For both the Yak and the CJ, the pneumatic system is one of the most important aspects, but almost continuously problematic. Over the years, I ended up replacing every check and shuttle value and pretty much all of the tubing before a long list of constantly appearing problems finally disappeared. Replaced the starter solenoid valve early in the game. Just comes with the territory. Here are some thoughts after years of work one the pneumatic system of my CJ.
  
    •  Use the highest quality tubing you can find. Avoid inexpensive, thin wall bargains. 
    •  New B-nuts and collars from Doug Sapp is the way to go. 
    •  Flaring tool that compresses the base of the flare rather than stretches it. Avoids creating a failure point. 
    •  Secure the tubing with Adel clamps. Vibration is the most common cause of failure. 
    •  Replace/rebuild the check/shuttle values at regular intervals. Corrosion is insidious. 
    •  Don’t forget to service the air/water separator twice a year.
    •  Lubricate the system with 50-50 mixture of 98% alcohol and glycerine every 3-4 months if you fly on a regular basis. 
    •  Get/borrow an ultrasonic leak detector. Will uncover much more than is obvious. 
    •  Replace old rubber/cloth actuator and brake lines. They do not age well. 
    •  Bypass everything in the aft cockpit. Not needed and just another source of potential leaks. 
    •  Replace the main and emergency air tanks with new from Doug Sapp. Close to failure-proof. 
  
  Do not get frustrated when some part of the pneumatic system fails. This is what we signed up for when purchasing these airplanes. Just fix it and move on. However, over time be proactive and plan to replace prior to failure the oldest parts, even if they are working. It’s not really if they will fail but rather when it will happen. To my way of thinking, it’s easiest to do this beforehand.

   Thanks Warren. Superb list. Where can I locate a flaring tool that  compresses rather than stretches? I have a cheapo one of the latter variety that  I've never liked.    
  Also, my recollection is that Doug Sapp recommends cod liver oil to  lubricate the system. I gather though that you've had success with the  alcohol/glycerine formula over the years.

				Hi Blitz;
   
  Just read Warren’s post which reminded me I should have advised that use of  the aircraft flaring tool for the 6 mm tubing requires the use of a small piece  of 400 grit (or close) wet-or-dry wrapped around the tubing to take up the .014”  clearance.  A small pain in the ass but not a problem.  For the 8mm  tubing the 5/16 setting is just fine.
  Perhaps Warren could advise if he has found a metric AIRCRAFT flaring tool  which would be great!  The standard (non-aircraft) metric flare is 90 deg.  (inc. angle) while all aircraft (including the CJ) use the universal aircraft  standard of 37.5 degs. (75 deg. inc.).
   
  The Parker aircraft flaring tool is an excellent device and will give you  perfect flares every time.
   
  Walt

				Walt,
 For those using replacement ¼ inch aluminum, the Rigid 377 flaring tool will also do a nice 37 degree flare and does not stretch the base of the flare.

       Thanks Warren. Superb list. Where can I locate a flaring tool    that compresses rather than stretches? I have a cheapo one of the latter    variety that I've never liked.      
    Also, my recollection is that Doug Sapp recommends cod liver oil to    lubricate the system. I gather though that you've had success with the    alcohol/glycerine formula over the years.

 For both the Yak and the      CJ, the pneumatic system is one of the most important aspects, but almost      continuously problematic. Over the years, I ended up replacing every check      and shuttle value and pretty much all of the tubing before a long list of      constantly appearing problems finally disappeared. Replaced the starter      solenoid valve early in the game. Just comes with the territory. Here are      some thoughts after years of work one the pneumatic system of my      CJ.
 
   •  Use the highest quality tubing you can find. Avoid      inexpensive, thin wall bargains. 
   •  New B-nuts and collars      from Doug Sapp is the way to go. 
   •  Flaring tool that      compresses the base of the flare rather than stretches it. Avoids creating a      failure point. 
   •  Secure the tubing with Adel clamps.      Vibration is the most common cause of failure. 
   •       Replace/rebuild the check/shuttle values at regular intervals. Corrosion is      insidious. 
   •  Don’t forget to service the air/water      separator twice a year.
   •  Lubricate the system with 50-50      mixture of 98% alcohol and glycerine every 3-4 months if you fly on a      regular basis. 
   •  Get/borrow an ultrasonic leak detector.      Will uncover much more than is obvious. 
   •  Replace old      rubber/cloth actuator and brake lines. They do not age well. 
        •  Bypass everything in the aft cockpit. Not needed and just another      source of potential leaks. 
   •  Replace the main and emergency      air tanks with new from Doug Sapp. Close to failure-proof. 
 
 Do not      get frustrated when some part of the pneumatic system fails. This is what we      signed up for when purchasing these airplanes. Just fix it and move on.      However, over time be proactive and plan to replace prior to failure the      oldest parts, even if they are working. It’s not really if they will fail      but rather when it will happen. To my way of thinking, it’s easiest to do      this beforehand.

				For 6 mm tubing, the ROL-AIR IMP.507-FBM will do a 37 degree metric flare. 
 For ¼ inch tubing, I like the Rigid 337.
