    OK, all of you engine people out there, I need help figuring out
    a problem...
    
    Enya 40 runs great, both at the high end and at idle.
    
    It takes a hard landing after a wheel is lost in flight.  I broke
    the prop and made a small divit.
    
    After I replaced the divit and cleaned the engine, I started it
    up.  Engine works great at the high end.  As I throttle back, it
    just dies, no final increase in RPM; no steady slow down.  It just
    stops.
    
    I checked the whole fuel system (klunk, lines ect) and even mounted
    the carb on an OS-40 (which works great, by the way).  So the problem
    has to be in the casting, bearings, crankshaft, piston, sleave,
    ect.  
    
    The only problem that I can find is that fuel is leaked out of the
    front bearing when the engine is stopped.  I don't know if it was
    like this before or not... I had never noticed it...
    
    Is it possible that a bad front bearing/seal would allow enough
    air in at low idle so that nothing is pulled into the carb???
    
    Thanks,
    jeff
    

    Jeff,
    
    I'm afraid I can't add much to the suggestions John's offered but
    I can substantiate what he said about fuel leakage out the fron-main
    bearing being normal.  As John says, this is how the bearing is
    lubed and cooled and all engines do it, though some more/less than
    others and the leakage may not always be visible.
    
    I had (still have) a Kraft .61 that leaked like a sieve out the front 
    end but it ran like a scalded-dog!  (This engine is still comparable
    to the newer generations of schneurle-ported engines and is a great
    sport engine...I have 3-of them.)  All ran great and all exhibited
    differing amounts of front-end leakage.  
    
    As John suggested, try a new plug first thing, then try _fresh_
    fuel to make absolutely certain yer' not leading yer'self down the
    garden-path.  If the problem persists, then a crankcase/compression
    leak is a logical next-place-to-look.  If there's still trouble
    after this, I'd be looking to assure that I reassembled the engine
    _precisely_ the same as it came apart...like John says, _MANY_ engine
    problems can trace their origin to improper reassembly after reassembly.

    There really wasn't a whole lot of dirt in and around the carb.
    I just wiped out the dirt and tried it again.
    
    I guess tonight I will have to disassemble it completly looking
    for scoring of the sleeve, ect...
    
    
    Thanks,
    jeff
    

    Jeff,
    
    I know you said the carb worked OK on another engine but this is
    the first place I'd suspect, based on yer' latest comment.  Remove
    the needle(s) and flush clean with model fuel, alcohol, WD-40 or
    whatever...just assure that all passages are clear.  BTW, count
    turns as you remove the needle(s) so you can reinstall them in
    approximately the same setting.
    
    If still no help, then maybe you'll have to tear down the engine 
    but if it didn't ingest a lot of dirt in the crash, I doubt if 
    this'll serve much purpose.  In any event, I'd recommend a simple
    tear-down _only_ in this instance.  That is, remove only the head,
    backplate, frontplate (if applicable) and carb.  Slosh dismantled
    engine around in some suitable solvent (even hot, soapy water works
    fine) while rotating crank until satisfied that all dirt, et. has 
    been removed.  Allow engine to dry or blow dry if you have access
    to an air hose.  Now _drown_ the innards with a suitable light oil
    like 3-in-1, Sears Turbine Oil or virtually any gun oil, pating
    particular attention to the bearings.  Reassemble _EXACTLY_ as the
    engine came apart (scribe marks are very helpful here so mark correct
    orientation of parts _BEFORE_ disassembly).

    I have an ENYA 9O 4-stroke and so far it runs real
    smooth and has alot of power. I've never owned or
    run a 2-stroke ENYA. I fly with a guy who has a couple
    2-strokes and they seem to run well. I just purchased
    a WORLD ENGINES E.G.A.S. to use with the 4-stroke for
    slower idle on my CG cub. Haven't installed it yet but
    it looks like a good alternative to the mechanical glow
    systems.

     I've owned an ENYA 19 control line & an ENYA 35 R/C. Both are older
    engines that I've had for several years. If the newer ones are any
    where near what the older ones are, then I highly recommend the
    ENYA. Both of mine are excellent performers. The 19 has plenty of
    power for its size and was easy starting. The 35 R/C was also easy
    starting, very nice idle, easy transition into midrange and very
    stong top end. If ENYA has maintained its quality over the years
    since these engines were manufactured (mid 70's), and I strongly
    suspect they have, then I'd not hesitate to purchase an ENYA. Price
    is the only thing that has kept me from purchasing one in resent
    years. My finances have dictated K&B as of late. Don't take that
    wrong though. I've had excellent luck with K&B. Its just that I'd
    rather have ENYA.
      Hope I've been of some help. 
     
    I saw an ENYA 90 4-stroke perform once. Talk about gobs of power!

    Yesterday I sent away for the Enya 45 CXTV. It's supposed to be
    a pretty powerful engine.
    
    
    I'll let you know when it gets here. I am planning it for a walt
    mocha Novi I just bought. Good kit. If you don't know it Walt was
    the owner and designer of all of the Balsa USA designs. Except for
    those within the last couple of years. He sold out why? Anyways
    he has started another kit manufacturing company and the quality
    was very good. The Novi design I bought is like a second generation
    Smoothie with improvements. Full doublers to behind the trailing
    edge,sheeted turtle decks etc. Should be a good sport flyer.

Additionally - it is the loudest .45 on the face of the earth.
This will make a great test bed for soft engine mounts, snuffler mufflers,
4 blade props, ducted exhaust, etc.

    What's the difference between an ENYA 45CX and an ENYA 45CXTV ?
    Back when I was putting together my first Cobra I was having a
    hard time getting an OS 50FSH to put in to it. I finally ended up
    getting an ENYA 45CX that was highly recommended as a replacement.
    
    Now that I have both engines, I like the OS 50 better but I'm impressed
    by the amount of abuse the ENYA took from me and its still going
    strong.
    
    Dan Eaton

I think you'll be very pleased with the Enya. I used lots of different ones 
back in the 70's and they took more abuse than I thought any engine could. I
had a control line combat .35 ship that I had shaved the head to 11:1 
compression and brought it straight in (85 degrees maybe) on tar, totalling 
the plane. Had to clean up the threads on the crank to get the nut off. NOTHING
WAS BENT. The engine was back in service within 100 RPM in the next ship. I
will admit that they truely are louder than average.

We didn't have an OS dealer in my area back then and Tower hadn't started till
a little later. I found Enya to be my lower cost workhorse with Supre Tigre and 
Webra being the high end (cost and performance) and Fox and McCoy (anyone else
buy a "Red Head"?) being disposables.

An important consideration is that Enya parts are usually easy to come by. If
my old hobby store owner didn't have it, the distributer did and it was there
the following week's delivery.

I ended up with about 8 of them in various stages of modification (they had 
thick castings for modification/polishing) and they all ran super. I never used
one up and they started in all sorts of weather.

    My nomination for the louest engine is the Webra Pro-mix ouch!!!!!
    thats loud Especially with an irvine mini-pipe,this is definatly
    the way to loose your flying site!!!!!

    I am considering the purchase of the ENYA 53 4stroker to power a
    Goldberg J3 aniversary cub.  Does anyone have any experience with
    this engine and what seems to be a good price for it.   I plan on
    mounting it inverted with on-board ignition.  Due to its small physical
    size, I think it should almost all fit inside the cowling. (I do
    plan to put cooling ducts in).  
    
    Thanks for any input

    Mr. Snow,
    
    Thanks for the info on the 53 in J-3.   I am in Columbus, Ohio
    (not very high) so it is looking like the Enya 53 may do the job.
    I have heard that the 53 is a high perf 4 stroker in that it is
    supposed to have the power of a 60/4 in a small package.  
    
    Does anyone have any 1st or 2nd hand info on the reliability of
    the 53 or other Enya 4 stroke engines?
    
    Thanks for your help,
    -jr
