        That sure sounds reasonable.   Are you the one with Multipoint Fuel Injection?

    the crankshaft flange isn't in engine but with the engine ready for prsu install the open pan is underneath it,i covered it with a rag and the blew the chips out with compressed air to keep them from going in the pan ,that's why the picture made me think of that I suppose

    What devilish scheme comes in the spring and halts all airplane building?

    I am so sore from it that I cant move without moaning!
    Hoping the recovery wont take too long.

    Sorry, I thought yours had the MPFI (multipoint fuel injection) not throttle body - guess someone else had MPFI?  I know how TBFI works - like a carb, only better in some ways.
    Thanks,  ED

    Is MFI mechanical fuel injection? I have the throttle body injection on mine and it seems to be working great after he got it set up.

    I sure wish you could get your brother to explain the MFI control for me.  I know that some conversions used the original computer even with carbs, but mine is just a Holly carb and an old-fashioned distributer modified for aircraft use.

    I should have remembered who built your engine - guess my memory pills don't work like they used to.
    But, the holes in the crank don't go into the engine?

    What controls the MPFI on an injected EA-81?  does it use a computer?

    What diameter is it?
     
    Warp props are very heavy duty and well built props, but, especially the square tip ones, are extremely heavy.  With the nickel leading edge this puts them over the max for the Moment of Inertia test that Paul was referring to.
     
    MOI Test Procedure
     
    The "B" gearbox can only tolerate 3000 kgcm2.
     
    The "C" & "E" gearboxes can tolerate 6000 kgcm2.
     
    The 912/914 gearboxes can also only tolerate 6000 kgcm2.  (Link)

    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!

    Do those holes go all the way through to the inside of the engine?   I don't think so, but need to go look at my books.

    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.

    Is this an Eggenfeldner engine?   Those large bits look like machining chips - but cant tell from photo.

    Soob engine trouble
    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

    Soob ignition maintenance
    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.
