I recently bought a never been run Enya 35III model 5224 on Ebay. Just wondering if anyone has any break in tips besides what I'm doing. I'm running S&W 5% nitro 26%castor/2%syn. fuel, a TopFlite 9x6 prop, rich 2 cycle, on a 42" stunter. I have the smallest of the 3 venturies and the low comp. head on it. I find I probably shouldn't really push the limit on stunts, it seems to run good with a few inside loops and inverted. Seems to get a little winded if I do a lot of consecutive stunts. I have about six 4oz. tanks of fuel through it. I have had a Evya 29IV-B model 5224 since the mid 1970's and have had periodic shut off problems with that on consecutive stunts. Is this a characteristic of Enyas? I was always running 10%nitro 22% 50/50castor/syn. I was recently advised, by someone who knows a whole lot more about this than me, to run the 5% nitro 28% castor in the Enya's. I've found the 29IV-B to be a very powerful engine. In fact, I put the high comp. head on it and it ripped the bellcrank out of my Flite Streak. The Flite Streak had met the asphalt many times before this crash so it's quite possible the BC platform strength was not 100%. Still it was awesome! One of the hardest crashes I've ever had. Plane was instant junk, and I knew it on impact.

Well Jerry...your double post is a bit prophetic! It usually take about twice as long to break in an Enya but the it's worth the wait. Seems to me that your problem maybe be related to tank issues along with a "green motor".

The 26% castor 2% syn should work. I remember we use to use some K&B 100 fuel that had 25% castor (if the memory still works) and it worked fine in most of the iron motors.

Jerry, I was recently reading the instructions for my Enya engines. Even my oldest Enya manual states the use of castor oil content of 20%. I run my Fox's with GMA 5/22 even though most will disagree with this practice. I tried this in my Enya .15's but they didn't seem to like it too much. I was given a gallon of Sig Champion 20% castor and used it in the Enya. This fuel worked great for me. I was previously using 25%. I truly believe this is too much oil. I think it was cooling the plug. Ken

Thanks for the reply. I was told the same by someone else, that Enyas take a long time to break in. A friend of mine told me Enyas have the hardest liners of any engine and take the longest to break in. My browser locked up, that's how I got the double post.

Yes Ken, you're right the Enya instructions say 20% castor. (if all else fails read the directions) I'll keep that in mind and cut back on the oil if I need to. I have the 28% for the 2 Fox 35's I have. I hate to have to take a third type of fuel to the field but that sounds like a better option than having a bad running engine.

My two cents worth.

I was having trouble running an Enya 29 I have had for years, in fact I hadn't run it for years and was using what I run my Fox 35's on, 28% castor oil based fuel. The Enya 29 ran ragged and rough, acted like too cold a plug no matter what plug I tried. Found my old notes from years ago and there it was, 20% oil only. The engine ran beautifully after this with an OS N0 8 plug. Same result with the Enya #3 plug and Taipan red plug (excellent plug BTW). Problem solved.

I emailed ken Enya about this and his reply was that Enya reccommends (same as their brochures) 20% oil, either castor or synth. Some guys certainly have success with higher oil content but my guess is they use a higher nitro content than I do. I never use nitro in any of my Enyas.

Greetings all from S.W.France......

I also have an Enya 35 [ 5224 ] which I bought from Enya Direct a while back.
Brilliant engine , superlative quality , but ...... Enyas take 'ages' to run-in properly.

I'm a luddite when it comes to running -in engines , especially the 'older style ' Enyas.

1. Bench runs , around 3/4 minutes , rich . Around 8,000 on the tach. No silencer fitted.
2. Low pitch prop , mine loved a Graupner 10x4.
3. Full cooling off period between runs.
4. 75/20 castor/5 nitro fuel.
5. At least 90 minutes of running-in time ....I know it's a chore but it pays off in the end.
6. My Enya now starts on the button on it's flying/running setting.

I now , after testing MANY props , find it prefers a Master 10x6 in the air. Around 9,000 at launch using a 17 % synthetic/5% castor mixed fuel.

Oh.... Invest in a Leonard Neumann ' strap on tongue muffler '....Great quality and no weight.

Enyas are worth the time and patience during careful running-in and will last forever if you look after them .

Hope this helps and kind regards ......Wonderful forum fellas,

You have to have the patience of Job to break in an old Enya ... I used Dukes Fuel and Fox Super Fuel back in 1970-72 on one 35.. I still have it.

One thing that might help is after 30-40 minutes of bench time (with no muffler)... finish the breaking in process in the air.. the cool air over the engine is a good thing.. kind of like breaking in an old Harley... ride it to break it in..

I think the old Enya's are the most forgiving and longest lasting engines ever made... and just about perfect for those tail heavy builds.. why add weight when you can add "an engine" ..

Robin.. did you get the Tower 40 running yet?

Jim

Jim , really nice to hear from you and hello from a sunny [ at last ! ] Charente.

Yes , I did get it running . But ..... I first sent it to Byron Barker [ the magician ! ] to work his mechanical magic so to speak. I then ran it in , usual ABC style. It's a 'cracker' as we say on this side of the pond. Great quality and a good 'looker'.

It loves to grunt around , 'switching' when it's supposed to and loves Randy's Cyclone 11x4.5 PROPS.

For any guys out there reading this post , Jim's the most honest guy to deal with on E-Bay I've ever encountered without a doubt !

You keep well Jim and thanks for getting in touch ,

Kind Regards ,

The Enya 35 is running great with a 9x6 TF Power Prop and the 5% nitro 26/2% castor/syn. fuel and a rich 2 cycle. Maybe it just needed a bit of time on it. It's got about 10 to 12 4oz. tanks of fuel through it. I'm limiting the consecutive manuvers and it hasn't missed a beat lately. It has even been starting on the first flip sometimes. I know some of you said to run it on the bench but I just don't have the patience or something for that. I'd rather adapt a flight pattern that works with the engine for break in. Is there an advantage to bench running them? I never did that with any engine. Not that I didn't know about it, I just have never done it. I would think that would make the engine run hotter than flying it for break in. Of course I suppose that could make the engine break in quicker.

Hi Jerry,

Running on the bench will help prevent an engine from going from rich to lean, as they often do before they are broken in. You can't control this with the plane in the air. I've had experiences where engines not completely broken in would do this.
