That's what I figured. It's been awhile since I've said something objectionable enough for a moderator to edit my post. Deleting a post on the other hand... Nevermind. Haha. Anyway... Back to our regularily scheduled forum chat.

Enya's, a most pleasant subject. Sadly I don't have any at the moment.

1QwkSport2.5r

Indeed!

I think I have 7 of them. 3- 15-IVs, an SS30bb, and 1 each 46-4C I, 60-4C, and an R120-4C. In the process of freshening up the 46-4C, and one of the .15s is NIB. The .15 I ran in recently was and still isn't an easy starter. I could not hand start it to save my life - I had to use a starter on it which I hate doing to bushing engines. It's got a bit over an hours time on it now, but I haven't tried hand starting it lately. Hand starting the 4-strokes scares me a bit so I always use the starter on those. Other than that, they're very pleasant running engines. I'm most impressed with my SS30 - it is a stellar runner and hand starts with one flick almost every time. I got it NIB for $40. Couldn't be happier.

The smallest one I had was the .25 Diesel, the largest was a1.55 which had an evil sounding exhaust note. It was a shrill bark compared to pleasant throb of a Saito, Laser or an OS. It was a smooth running engine though to be fair. The .53 is a real sweetheart, it stood right in the middle in power between a Saito .56 and an OS .52. I hope to have another some day.
PS, if you check in the MarketPlace there are only two Enyas, they move very quickly, there is an old loop scavenged .60 and a newer .40.

Once I figured out how to start my 80 4C, it starts faithfully on the third flip. Such a sweet running engine. I've got to find a good airframe for it. It deserves one.

Steve, if I remember correctly there was a small block .80 and a large block .80 or am I mistaken and it was the .90 that was like that.

Tim, I found my own two pictures of the Enya .60 AAC I had, on page two of this thread.

That's a good question. I'm not sure.

Steve I may have answered my own question, here is a shot of an Enya .90 and a 1.20 GP I had, hope you don't mind my little nostalgia fit.

stevegauth30

Not much difference.

Many years ago, when the FAI and AMA decided to allow 1.20 four strokes to compete with .61 two stroke engines, it caught the model engine companies by surprise. The companies wre expecting them to allow .91 four stroke engines instead. Enya had a coup of sorts when they bored and stroked their large case .80 four stroke engine and turned it into a 1,20 four stroke engine. Enya had the luxury of being about two years ahead of everyone else with having a 1.20 four stroke engine to sell.

Anyway, yes the first Enya .80 four stroke engines were quite robust and strongly built. If you put the early .80 beside the first version 1.20 engine you can see that they are the same size.

buzzard bait

I think it was the 90 that they bored out to a 120, not the 80. Then they decided it wasn't big enough for the porting they wanted and came out with the larger R120.

The 90 became a bit of an orphan...too heavy for its displacement by most standards.

The early 120 was in the same case as the .90. I thought the .60 and .80 4-strokes were in a slightly smaller case than the .90. Maybe not. The 120 wasn't on the market long before they released the R120-4C and R120-4C GP which was in a bigger case and more robust than the older 120. On the larger props, both 120s turn close to the same rpm but on the smaller props, the R120 pulls ahead. The R version breathes a lot better due to a larger carburetor, larger/smoother intake, and larger valves. They're all great engines though, and they would rather turn up a bit than be lugged down with big props although they will happily... Just messier.

I'd love to own one of those powerhouses someday. I spent all of my saved hobby money on a Jett .56 AAC. The Jett probably makes more power, but the Enya is more timeless in appearance. I've heard the Enya AAC engines weren't all that "pinchy" like some of the other (true) ABC engines were. That is one trait I like to see in an ABC or AAC engine. At any rate, the 60XF-4 is a beautiful engine. Someday I'll get my hands on one - but I'm picky. It will need to be NIB. (Snicker)

Correct, that one had no pinch, with the glow plug out and the backplate off the piston would fall from anything less than tdc. the thing was virtually friction free. The entire rotating assembly would move with a feather touch.

earlwb

Yes you are correct in that it was the 90 four cycle engine that was bored and stroked to make it a 1.20. My fingers just weren't working right on the keyboard earlier.

The .60 and the .80 shared the same crankcase too. They had bored and stroked the .60 to make it a .80. But these two engines wind up being very heavy in comparison to some other equivalent four stroke engines. One could use .80 parts to upgrade their .60 too. But they do turn much higher RPMs than the competition can.

Hi,
Is there anyone here that has a copy of the cam alignment/install procedure for the ENYA 80-4C ??
I would really appreciate a post with it.
Thanx,
Bob Blasi

My Feedback: (102)

Bob, there is a dimple in each cam gear just inside of the teeth near the edge, the dot/dimple points to the center of the drive pinion gear.

Hey Earl, that splains it better than my 29 words.

1QwkSport2.5r

It even shows how to run them in reverse rotation. I remember seeing one of those documents posted on the other forum recently. I should save a copy of that. I might experiment with reverse rotation props on projects later on.

Thanx gentlemen,

You saved my hide once again !!!
Trying to find info on the net about the 80-4C is like pullin teeth.
Thanx again,

You are most welcome.

I posted on the CL forum as the .19 is pretty widely used in those circles (pun intended ) but thought i might ask here as well. I just acquired a Enya 19 IV today that was given to me after being found in an old barn of all places, along with a bunch of other stuff. When I got it this engine it was frozen solid, but otherwise looked to be in pretty good shape. So I went to work on it, got it free'd up, mounted it on the bench, and what do you know but it runs pretty good! The only concern that I have is that the rod seems to be still frozen to the wrist pin and the pin is turning in the piston itself instead of the rod rotating on the pin. I do not see any kind of a wrist pin circlip either? I have read where some of these engine have brass inserts on either side of the wrist pin to keep it place, but I do not know if the .19 IV has this or not.


Right now I can move the rod/wrist pin back and forth in the piston, but as I said the pin moves and rotates with the rod. If I move it to either side of the piston the wrist pin will protrude about .5mm one way, or 1mm the other. Do I need to soak the piston/wrist pin/rod to get the wrist pin free? And should there be circlips keeping the wrist pin located? As of right now I think my intentions are to build a period correct r/c airframe like a sig seniorita or a Goldberg falcon 56 or similar for it to go in. I believe a M153 strap on muffler will work with it as well since I will need a muffler to fly it at our field.


Thanks for any help!
