New Enya 15 Diesel mk2 reproduction from the 1950's.
Ken Enya has just announced a production run of 60 new Enya 15 D mk2's from the late 1950's.
Should be available early in the new year.
There will be a ballot and the lucky 60 winners will be able to buy one for about 30000 Yen, or about USD300.
The engine will come with both r/c throttle and c/l venturi/NVA.

I purchased an original one of these in 1963, the "15D Mk II TV". The throttle looked a bit simpler than this one, but it worked OK.
Unfortunately, it's one of the many engines I no longer possess...

SM stands for "special muffler" it is longer and has an extra chamber to make it more quiet.

The first series of CX 11D Ultra's had the 'airbleed' R/C carb.
The latest run have the twin needle ("TN") carb with an angled back main needle.
I hope ENYA commission a large run of traditional Tommy Bar equipped compression verniers, and sell them as spares. I will happily buy a couple for my CX 11D Ultra and SS 30 BB.

What is the porting arrangement on this reproduction? Is it good old crossflow, or more like a "vortex" arrangement (like the MVVS 2 cc Junior)?

The mk1 Enya was a landmark diesel and a strong influence on their design direction. Unfortunately they had weak cranks, a situation fixed with the mk2. In retrospect the former may have been fine with modern fuels.
There's a lot written about the OS/Enya diesel "wars" in the late 1950's. You have to remember that the era was the peak of c/l, and 2.5cc racing was very popular. The market for that size diesel was huge. While the Oliver was king, it took up to 18 months to obtain an engine and they were subject to a rather arbitrary customs duty. Even getting the UK currency for the purchase could be difficult.
You could buy the Enya, and later the OS product across the counter at the local hobby shop.
What is the thread size on the Enya CX 11 Diesel? I'd guess about standard M5 x .8. Can someone check?
There's an interesting discussion about the OS 15D and the Enya on Adrian Duncan's report on the former on the MEN site here:
http://www.modelenginenews.org/ad/max15d.html
I have a near new Enya 15D mk2 that is going into a Peacemaker. While I was running it in I was talking to a chap who used to fly team race during the era. He had both the Enya and the OS diesels. He explained that the OS was a disappointment. It was bigger, heavier, slightly less powerful, and most importantly far thirstier than the Enya.
In the end the Olivers increased their production and everyone bought them.
Still the Enya's like the other TBR racing engines of the era are superb sports engines. That's not something you can say about the ETA's etc.that followed them.
The local OS dealer in OZ is reliably reported to have bought back the diesel from disappointed customers rather than allow them to trash the brand overall.
All the Enya 15Ds tests are available here, http://sceptreflight.net/Model%20Eng...20Diesels.html
Makes interesting reading.

By the way the Enya diesel is not TBR. I may have given that impression above. It has a single main BB and a pressed in plain bearing. The OS was TBR.

In one of the reviews, a comment was made that the fit, and smoothness of the single ball raced shaft was better than some TBR engines.

The point I was trying to make is that not all carbs equipped with an airbleed are the same. The pictured one on the .15 is indeed a plain airbleed carb, while the ones with a larger carb housing have a metering feature in the throttle barrel. There is still an airbleed screw on these, but they are a more sophisticated carb than a simple airbleed one. At least all of my CX 11 have the larger housing and the metering feature, including the earlier non-Ultra AAC ones.

Which carb do you have then? It sounded like you already have the metering one, which has a larger housing than a regular airbleed one?
The twin needle one only came with the glow version, as far as I know, and the Diesel ones came/come with the improved metering one (easily identified by the larger carb housing). Below is a picture with the glow (.11 Ultra) on the left with twin needle carb and the Diesel .11 on the right (with the metering carb). A plain airbleed carb would look like the one above on the .15 engine or the Enya 09 glow for instance.

OK Enya whiz's just downloaded the PDF file from Enya on the 11CXD info sheet and parts sheet it does show 2BBs at the top
It lists (2) a U11CXD and 11CXD what is the difference my guess that the U may be a control line carb?? martin
and will the twin needle carb for the 15 with the angled needle fit??

I guess the U stands for "Ultra" which is the later ABC version of the 11CX. The earlier "non-ultra" were AAC. There might be a slight difference in their true cylinder volume also (with the Ultra being larger), I can't remember the details...
