@Wajet & 1QwkSport2,5r: please cool down now.
We often have here questions about unknown engines, I helped in the past to identify them so good as I could, nothing other here.
When I wrote "I'm not sure if this is an R120", I just meant that and only that, it wasn't clearly to see on the first picture which version it was.
Next thing is, I'm not a natural english speaker, to be exact, I never learned english in a school or seminar or something, It's just from
self teaching, reading and posting in forums like this one here. May be we try german next (or better, my russian wich I had to learn in
the school), we already discussed that in the past.
I know that the old 120 was build using the crankcase from the 90-4c and the 90 was milled off like that on the engine on the picture.
I know, that Enya used a new crankcase for the R120 where the 120 is casted in. I NOW know, that Enya must have build R120s
using the Crankcase from the new R155 (since there was never a R90) using a smaller cylinder and milled of the 155 from the crankcase to engrave the 120 as its done one your engine. There is no possible other reason for doing this... so far for the facts.
An seller that sells an item in a box which is telling a different type number must not be a jerk, Such things happen all days, we deal with old engines here and the seller himself could have bought an item in a false box w/o knowing about that. Possibly the first owner has passed away in the meantime. Nothing bad about this, it just needs to be clarified up later.
As for the feedbacks: I've never dealed here at RCU, so I don't have any feedbacks.
I never could deal here at RCU if all People are think like you 1QwkSport2,5r, since no one would trust me.
Chicken and egg problem?
That's just my 2 cent.
Regards,
Holm

I'm as cool as ice my friend. And as far as not bring able to tell in the first picture, well, I had no problem seeing the screws that go into the rear of the cambox cover with the L bracket. I compared to your pictures, no problem here.
Next, I have no issues understanding your English. It's a little rough, but certainly understandable. No problem here.
It would make sense to mill off the 155 designation for the 120's, perhaps they had an over-abundance of R155 crankcases that they needed to use? Are all R120's engraved like that? Who knows. If someone does, do tell.
If you're selling something claiming its "X" in an "X" box, it better be "X". Now I understand misunderstandings happen..... But a seller should know what he or she is selling before selling it. I bought some Carburetors for some engines of mine and the guy "thought" they'd fit and that he measured them. Turns out he didn't measure them correctly and they were too small. I then had to send them back costing ME money for HIS mistake. I don't like paying for someone else's mistakes. Its a common sense courtesy, know what you're selling.
Now for the feedback bit. I don't go off of feedback alone. If you post in the forum, and are knowledgeable, I'd likely look past the feedback bit. If you have 6 posts and joined a week ago, that's a different story. So yes Holm, I would deal with you if we made a deal on something.
So in the end of this huge rant, the morale of the story is: things aren't always as they seem... But sometimes they are. One just has to look a little deeper.
So, back to engines. What props do R120 owners prefer to use on them? I do not use wood props, mainly APC. Based on Clarence Lee's engine test article, the R120 really shines on the smaller props. It turns an 18x6 at the same rpm as the regular 120, so it is definitely a better performing engine in the upper rpm band. Here's the article from RCM magazine: http://www.rcmplans.com/issues/requested/content/reviews/pdf/r-rv-enya120-011988-1-1.pdf

1QwkSport2,5r - I'm glad to see your performance drop with the stock muffler isn't 3000 rpm or 2000 rpm, but 870 rpm. Still a bit higher than you'd expect, but at least it's not beyond the bounds of credibility.
I finally got a chance to do a bit more testing of my plain-bearing SS30 with and without stock muffler - this time on a decent test bench. Got some photos of the tacho, but forgot to make sure the engine was in them as well! Anyway, with an APC 9x6, I recorded 13430 rpm with the muffler, and 13780 without, ie a difference of 350 rpm. I measured this both acoustically and optically. I'm quite satisfied that this accurately reflects the performance of the engine, and is also in keeping with what I've experienced when flying with it. An SS30-using friend who doesn't post here also got in touch and reported a maximum difference of 'a few hundred'.
Can we possibly agree now that the stock muffler doesn't suck, and has a fairly minimal effect on the performance? If I seemed a bit cranky about this, it's because these guys are making good stuff, and the last thing they (or we) need is for people to repeatedly (and erroneously) claim online that some of their products 'suck'. It must be hard enough for them to stay in business as it is, and if we let that sort of thing go unchallenged, then before long all we'll have left to us is cheap Chinese electric motors.

Enya makes a fine engine no doubt. I'll have my third Enya on the way soon. They blow OS out of the water and then some.

There's only one person we can really please in these forums and that is ourselves. I think the real test of satisfaction,1QwkSport2.5r is when you get that sweet Enya .30 mounted on an aircraft with your muffler of choice and you have a sweet combination of both. Then the muffler issue becomes nothing more than a hill of beans. I have to agree with you on the Enyas, so far they seem to be really sweet motors that although can be obtained on E-Bay for a song, are really well performers for sport aircraft even though most are not Schneurles. I'm having a blast with the ones I have so far.

My third Enya should be arriving tomorrow or Thursday, an R120-4C. I mentioned it previously, but never got an answer to a couple questions... Clarence Lee tested the engine for RCM back in '04 or so... Using props ranging from 14x6 up to 18x6 or 18x8, I don't recall which off hand. What would be a good all around prop for it? I was going to pick up 2 or 3 props for it, maybe a 14x8 and a 15x8, APC of course. The R120 likes smaller props based on the article, so I'm looking at the 10,000-11,000rpm range. It ran 11,500rpm on a TF 14x6 wood prop, I figure an APC would load the engine a bit more?
There is not much info about the R120 out there.... Anyone else on here have one?

I find it worth asking what guys are using on them, in real world usage. Not that I doubt Enya, so don't take it as such.

Enya .15-III TV Improvised Muffler Strap
Missing the bolts and strap, recently I made an improvised one from pipe hangar strap and 2 bolts from my computer parts salvaged bolts bin. Now my Enya .15-III TV sports the latest muffler.

I picked up that exact muffler from one of my hobby shops for $5 and gave it to my buddy for an Enya .09 IV. No word on how it runs, its a loop scavenged engine.

This particular muffler is for a .15 to .19 Enya. I don't think it will work for a .09, because the exhaust opening is considerably longer than for the .09 (got 2 of them, both III's, but I don't think there is much difference between III and IV crankcase). One of those, I'm using a Dubro Mini-Muff-L-Aire II with spring exhaust restricter removed (for CL) and the other, a venerable Tatone .09-.19 Peace Pipe. The Tatone is too small for anything larger than an .09 - .10.

I checked it to the exhaust stack on the .09 and it fit. It's close to leaking but a little permatex would take care of that. The .09 IV I had was originally set up for an exhaust baffle connected to the throttle. The engine was a friend's and I do not have it anymore so I cannot post a picture of it. It was a close fit.

My Enya 4-strokes side by side. The R120-4C is a beast compared to the 60-4C. I figured the 120 would be bigger than it is... The R120 is pretty much pristine. It turns over nice, compression is really strong, and is overall pretty smooth. This engine will be a hand-flip start only, my E. starter won't turn this engine over.

That sizing difference would be expected, 1QwkSport2.5r. to double the displacement volume would require cube root of 2 or 126% upsizing, which seems to be reflected in the photo when one looks at the cylinder size.

I knew there would be a size difference.. I haven't handled any engines bigger than my ST S90, so I was expecting weedeater engine size.... Seems a strange comparison, but I have a 16cc Stihl trimmer engine. The jug is about 1/4 the size of the rest of the crankcase and flywheel.
I've been trying to get to the hobby shop to grab a prop or two but I've been working a LOT lately...

Given the nature of Enya 4-strokes to rust like crazy in the cambox area, I took this R120 down to look it over, oil it, reset th valve lash and get it ready to get run-in. It's had a few tanks through it, but by the looks of the ring, it hasn't run much. Almost zero color change on the ring. The choke mechanism is a little different, hoping it is as effective as the old style choke. This one will have to get hand started I think. The compression is crazy impressive, and its not broke in yet. So a few pics of the innards.
Big valves...
Weird spot in the liner, might just be from the recess in the piston not touching the liner.
Cam box is pristine! Looks better than my 60-4C before I ran it and it was unrun when I got it.
The piston and ring. I'll get a Bowman ring to have in my parts box.
Should I be using the locating pins in the prop driver or is it not worth it? I'll be using a spinner nut and locking nut.

How about this for a belated B/Day present from good friends.
Anyone out there know where I can get one of the tear drop exhaust deflectors that come with these 60 Typhoons.
Well! Just asking....lol

Small displacement Enya 2 cycle engines
Lately I've been enjoying are my legacy iron piston Enya engines. Folks were amazed yesterday how long it flew on only one ounce of fuel on my 40" span Sureflite foam Cessna 180. Also, they were curious about this odd looking engine, which I explained was a 1966 Enya .09-III TV with Tatone .09-.19 Peace Pipe muffler with NOS Top Flite 7x6 wood prop. Gary, a long time modeler, familiar with these engines contributed how he liked the sound of the engine. It has a slightly lower growl, able to swing steeper pitched or wider diameter props at a slower RPM than Schneurle, but pull the plane with the same authority.
This is ditto for my Enya .15-III TV, swinging an 8x6 prop giving it the same speed in flight as an OS Max .15FP Schneurle with 8x4 prop on my Ringmaster Junior.
These older cross scavenged Enya engines are strong torque engines.

I have 3 engines in my Enya collection. My favorite engine, an SS30bb, a 60-4C, and a R120-4C. They all run really nicely on just 5% nitro and they will hand start easily. I can usually get the SS30 to fire off with one backflip. Superb engines.
