    That is what we thought Mike,looked like someone tapped a hole ,maybe its been there since the engine was rebuilt, I should of pulled the pan when I bought the engine but never thought of it, I will be inspecting the oil filter on every oil change from now on.Ed , Karlo Kunner built this engine and redrive,I had his number but he must of changed it, no longer in service

    Well, my the last assembly attempt held through two quick full throttle bursts.  I'll have the entire engine break-in period and some pretty extensive water trials to convince myself that it's solid. 

     

    It's the warp drive 3 blade, square tip, with nickle leading edges.   After the plane is flying, I'm going to assess how it gets off the water.  I'm definitely not near that point yet, so hesitate to spend to much time thinking about it,  but two tricks I might consider would be one of the adjustable propeller hubs and a Rotax Rick 670 conversion.   If I do end up shopping new props, moment and weight will definitely be a prime factor!

    first thing that came to my mind was chips from a tap.my rotary flight int. redrive requires tapping the end of the crankshaft from the obscure 9 mm to common hardened 5/16 thread  , those look like the chips that came off my crankshaft  . but I don't know where they would have been hiding for 200 hours.

         I don't know what dual point / pickup conversion you have, but there have been problems with some of them.  I have the plans for the conversion, but don't plan to use it. 

          I think that SuberAvid may have had some bad experience with that.  The dual coils are OK, and I think he runs them.  But, I have been around cars since the 1940s, and have never known of a coil failure.

          There are no "hours/time" on the distributer parts, just routine inspections and setting/replacing points/rotary button as needed.

         I saw EA-81 Soobs in Alaska with 3-400K miles on them, without an overhaul, and still going, although the old bodies were badly rusted out.

    Some of the early computers had to be replaced, but with good general maintenance, these engines last a long time.

    After 20hrs on the engine since I have owned it I decided to pull the oil pan off since the gasket was no longer sealing and was just going to silicone back up .once I got it off and looked inside it wasn't pretty , alot of chunks of aluminum were laying in the bottom.I cut open the oil filter and it to was loaded with aluminum bits. We tore the engine right down  and have not found anything damaged. The gear reduction was inspected and also nothing wrong there either. If the previous owner was telling the truth there is now 220 hrs total on the engine and shows very little wear. The only thing we could find was maybe a poor casting on the case were it looks like maybe some pieces may have come from. I'm am sending the cases away  guess they can pressure test them and look for cracks, Just wondering if anyone else has come across this mystery

    I thought I better start a new thread Ed. What specifically would be considered proper ignition maintenance on the soob ea81 with the nippon denso electronic distributer? Buy new every ? many hours. They are about $500 if I remember right. I bought all the stuff to do the dual LS 1 coil conversion with a dual pickup distributer but just haven't got around to it. Going to change my belt right away as well as it has been a few years. B

    I have heard only 2 reports of EA-81 failures - but there may have been others.  In both cases it was ignition failure because of poor maintenance.

    I would say that the EA-81 has a better record than some other engines.

    A friend of mine wrecked his new RV with an Soob-2.5, but it was not the fault of the engine - he had put an untried, untested, experimental, Eggenfeldner Supercharger on the engine and it failed.

    Robert,

          Unless you have a magneto engine, and the high-powered strobe lights, you shouldn't have to worry about induced static.  Although you could get an alternator whine in some cases, but a condenser on the alty usually cures that.

    I've had my radio mounted on the left side in all my Avids and never noticed noise from the master switch.  I use a Vertex Standard VXA - 220.  I like it mounted where it's easy to change the channel and such.  Jim Chuk

    just curious what others have done regarding their panel layout. I'm going to be using a handheld radio (currently have Icom IC-A6) and the best place for me to mount it is on the left side of the panel but this puts it right next to the master switch and I'm concerned about getting unwanted noises from the engine. would I be ok if I ran shielded wire to both the master and radio power supply? and a good ground? I've seen others have them next to each other just not sure if they have issues or not. I believe Joey's is like this?? or should I try and relocate the radio to the right side of the panel which I don't want to do. I will be cutting a hole for the radio and making a box riveted to the back side so the radio will be flush with the panel but still able to be removed easily if needed. input and pics would be great. I'm hoping to finish cutting out the panel this week :)

    Mr. Perry, Sir!

     

    Thanks for sharing my tiny little seaplaneforum.com here with the gang. :)

     

    Mark,

     

    The answer to the security question is in the logo and its "ʞɹoʍʇǝN" (including the five most common ways to misspell that word). Makes sense to type the word right side up. Generally those who can't figure it out will eventually contact me and I'll set them up. Thank the Chinese & Russian computer pro's for this requirement.

    Says the guy whose gone to funerals of Subaru pilots. My minor gearbox issue, stemming from a too heavy prop, didn't KILL me. Don't even try going there.

    I've derailed this thread too much already, sorry cowlove. I'll go away now.

    10 mm from spruce is garbage. Go with the 1/2 inch aircraft grade. 8 wraps even spacing on wide gear. Can't remember the total length eye to eye but 110 inches comes to mind. To tight and you bend stuff, To loose and the suspension sags. Check old posts on here as this has been hashed out before.  Use a set of spark plug boot pliers to pull on the cord. Cheers. B
