    Hunting with your Avid, August 2018
    I was not a very successful hunting year this year (so far) but it is always full of fun, challenges and a great chance to enjoy the beauty of God' creation.  Getting to hunt with your plane adds another element of fun and challenge to it for sure.  This year the winds and rain made us pretty happy to make it home without some serious damage.  We ended up bugging out of our sheep spot earlier than intended after getting blasted by the winds.  We had double duck bills and tie downs on each wing and tails and were glad they held.  The tents were smashed and a constantly havening to be restaked and retied down.  When the river started flowing heavily between our landing area and our camp spot we found another place we could get to to take off, then when the water started flowing between our camp and that area we decided to get out as soon as the winds gave us a chance.  Spent 2 days at the Rohn cabin which was kind of relaxing but wishing we had enough fuel to get out to another hunting spot.

    I've put over 500 hrs on mine.  It's been good to me.  Early solid lifter engines are better than later hydraulic lifter engines.  Supposedly, the third generation engines are good as well.  I would ask what the serial # is on this engine.   JImChuk

    Are you using paper element fuel filters with pre-mixed gas or is that part of your new system?

    I was mistaken.  the 1990 version of the 582 manual states, on page 15: "Cylinder head temperatures are measured at the spark plug seat.  Exhaust gas temperatures are measured at 100 mm (3.94 in.) from the cylinder sleeve."   It would seem logical to use the flange as the reference for these probes, but no!  I had now better check the locations of my EGT probes. Thanks for the correction.

    I've been turning wrenches on 0-320's for many years and they are solid engines if treated right. I've had several go 2400-2500 hours without a major OH.  And I've had several barely make 1000 without a cyl change. Mainly due to poor operation by the owner/pilot. As long as compression, oil pressure, and temp is good, I wouldn't be too concerned.  A smart operator could squeeze 3000 hrs outta one. You will rarely see a cont make TBO without serious rework. Not counting the old A-65's and 85's. I've seen them fly for years carrying 10-15 lbs oil pressure at full throttle and just enough compression to start. When Cont went with the 0-200, things went south somewhat. Probably trying to squeeze more HP outta the same basic engine. I've seen a lot of cracked heads on the 0-200 thru the years. Just my worthless hillbilly opinion.

    Not sure where you got those numbers. 38mm or 1.49 inches from the flange face.

    Manu, 
    It occurred to me that your airframe may not have the pully and rope guide mounts welded on.  Here is a picture of mine.  They are welded on to the V-strut.

    I know someone that just had their 320 rebuilt after 2990 hours since major. I don't think they did much other than change the oil either. If compressions are good and it runs smooth, keep the sucker in the air!

    Hi Manu,
    My plane has a pulley allowing the pull-starter to be operated from inside.
    With this set-up it's easy to do the pull-start while seated inside the cabin.   At first I thought I had to do it from outside, but not so!  It's much easier with shoulder belt slipped down; usually I un-clip the seat belt for the start.  I push with my foot against those two slanted tubes in between the rudder pedal sets.  Effecting a re-start while flying could be challenging, though - not enough hands to fly the plane too.  Maybe if I had a better trim setup...  I'll be keen to find out how well your trim tab works.

    I got ahold of a c model rear dash and got it to work in my mk 4 . I'm sure there are more out there. I like how it came out now I have room behind me with a pocket and the baggage compartment.

    I was in the same boat when I got my plane. I got it in a April and didn't fly until October because of the mess the previous owners made. It definitely sucks but you'll get a better understanding of your plane if you rip into everything and inspect it yourself.

    The unquenchable EGT
    Since day one of my little planes new life I have been unable to get my cruise EGT temps to acceptable levels.
    Here is the things I have done or tried:
    1. Checked probe location and found that someone had placed the probes holes 3.5 inches out on the Exhaust Manifold. Welded up the holes and re-drilled them 38MM (1.49 inches) out from the face of the port. Installed new probes.
    2. Rebuilt cards with new jetting and leaned the Idler circuit
    3. Needle clip to the richest setting. Anything leaner that the richest position made the EGT temp rise over 1200 in cruise. 
    4. Added pitch to the prop. This was the only thing that seemed to help but it took so much pitch that the performance was not acceptable for normal operation.  
    5. Purchased a longer propeller to load the engine. Again high pitch setting was the only noticeable difference.
    6. Purchased and installed one size bigger Jet needle. Didn't see much of a change to the mid range as reported by others. In fact I seen a slight raise in the temps.
    7. Read every article I could find. CPS, Ultralight news, several independent articles, this form, Kitfox form, and the Rotax form. Most articles I copied and saved in my builders reference manual.
    8. Monitored Plug color per Jimchuk. The plugs said I was OK so I continued to keep searching.
     
    I was talking to a friend the other day and was explaining to him what I'd been dealing with. He asked if I had tried a larger main jet. I told him that my temps were good at WOT and I didn't believe this was the problem. He suggested I install the next larger main jet, run it at the current needle setting, lean the needle if needed and see if that had any effect on the my mid-range problem. At this point I was willing to try anything. I threw in the next bigger set of main jets and took it for a flight around the pattern. What did I see......hotter EGT temps than before. You have to be kidding me I thought!!! I thought adding fuel cools the circuit?? Why was it that every time I added more fuel with a jet temps showed hotter??? 
    I went home, got my articles out and started reading through them again. I found the answer and it had to do with the installation of the EGT probes. If you use the 1" EGT probe (which I did)you have to shim the probe out with 7 AN-3 washers (which I didnt) so the tip of the probe is placed inside the manifold no deeper than half the diameter of the pipe. If you insert the tip of the probe all the way to the other side you are outside the cone of the flame. The cone of the flame (cooler part of the flame) is where the temperature is supposed to be taken. Anything outside of that area will produce hotter readings. As the article explained.... you will know this by raising EGT temperatures if you enrichen the circuit. When you add more fuel to the system the excess fuel gets pushed out of the cylinder and is burned inside the manifold. The more flame the hotter temp 
    Now you can purchase probes with 1/2 inch long sensors right from Westach. The bayonet probes can be adjusted. Unfortunately I cut the excess clamp off which made one of them to short to add the washer between the probe and the pipe. I was able to install washers under one of my probes. So far it looks like this was the problem all the time. 
    A lot of the headaches I've ran into with buying someone else's project was because things were installed incorrectly some of which I took apart and reinstalled back the same way. If you buy someone else's project it never hurts to double check the installation instructions on everything. 
    I hope this will help someone who may have the same issue or as Joey called it is" Chasing a Mermaid".

  19. NorthIdahoAvidflyer added a post in a topic New prop was a flop   

    Revised Update:  I talked to a friend who runs one of these props on the same engine configuration and he recommended I pull the hub apart and check my pitch blocks. He said he always had solid readings after re-pitching with about a 300 rpm change per degree. He has been very happy with this prop. I was not seeing that kind of RPM change, RPM was erratic and the prop was loud at certain RPM settings.  
    I pulled the prop hub apart and sure enough there was one set of 10 degree pitching blocks with the 11's. One blade was one degree out from the others. Not sure how this happened. I received three different pitching blocks (10,11,12's) so I pulled them all out to make sure that I had equal amounts of each which I did. I thought I was very careful when changing out the blocks not to get them mixed up but I didn't check them out of the bags either. I re matched all the pitching blocks, inspected the blades/hub, reinstalled the correct blocks, re-torqued the hub and did another test run. Boy what a difference!
    The 12's produced 5100 static, 6000 in climb, 6600 wot level flight with a 92 mph cruise. The 11's produced 5300 static, 6200 in climb, 6800 wot level flight and just over 87 mph. I have not ran the 10's because the 11's product the range I want. I am going to run the prop a few hours and see what i think about it. I flew it for an hour and it pulls good on climb and is very smooth. I may have to retract my original statement of it being a flop.
    It's interesting to me that how one blade being one degree out didn't have a major effect on the smoothness. This prop ran smoother with one blade one degree out than the GSC does on any given day. If you were to set one blade out one degree on the GSC I believe you would know it for sure. I believe the flexibility of the Ultra-prop 2 made it harder to detect. 
    Lesson learned. Double checked everything,,, Assume nothing.

    If would do it I would just weld a small bracket on the tube to bolt the strut.

    I don't know how far you are from Tri-Cities Wa, but Jim Fish did my tailwheel training in my Magnum. Jim is a good friend and one of those million hour flys anything really well pilots. His personal plane is "Pinocchio" a 540 powered extended wing and fuselage PA 22/20 thing. He has a ton of tail wheel time. He LOVES the Magnum. He is also our local Designated Pilot Examiner. Here is his Bio:

    My Magnum has a 150 HP 0-320. 7:1 compression. I ran ethanol free auto gas. TBO is supposed to be 2000 hours. I only flew it for 450 hours before damaging the plane in a bad landing. (It is next on my list to fix) Mine weighed in at 1050 empty. There are plenty of things I can do to lower that when I put it back together. I should be able to come in at 1000 and still have decent instrumentation. It performed wonderfully, a real ripper getting off the ground and climbing out. It was my first "GA" air cooled engine, so I don't know how they behave for most people, but I love it. I could cruise along around 90 MPH and burn around 5 GPH all leaned out. The nice thing was I generally flew it at very low power levels so I could really lean the shit out of it without fear of hurting anything, so I could get to within 1/2 to 1 GPH of my friends flying 912's on their much smaller Avids at the same speeds. My lycoming burned exactly 1 quart of oil every 50 hours all 450 hours so I never had to put oil in between changes. That is once I figured out that the "top" quart of oil pumped out the breather tube very quickly making a mess out of the bottom of the plane. Once I learned that and put a quart less in to start with, it didn't really use any oil. Compression was/is all 79/80 right up until I quit flying it. 
    My Magnum would do about 130 at full throttle level flight near sea level, but it sucked gas like nobody's business so I didn't really fly it that way.
    The Magnum is a very special plane, really in a different league than all the other Avids,
    I would be comfortable flying beyond TBO if having oil analyzed and cutting open and inspecting filter element every oil change.

    I installed a set too and they are working good. 
    Turbo, Those other plugs came but I received an email stating that I should check the order, I checked the order and they sent me the wrong plugs. I have an email back out to then asking what The would like me to do. I'll let you know when they rectify the order.

    Thank you Barry. The owner stated that the engine was is good health at it's last check-up.  He feels it will run another 1000 hours no problem. One never knows about those things. Keep checking filters and compression is all a guy can do until something does not look right. 
    Thanks for the information.
