Hiya Guy's,
 
Well, I need your help once again.......................
 
A couple of days ago I managed to break off the fuel feed nipple from the spray bar / needle valve assembly of my Enya 30BB.
 
I've been in touch with Steve Webb models (Enya Importers) and bought what I thought was a new replacement. But I've discovered that its not quite the right size. Apparently they only stock the Enya 30BB with twin valves known as TN. Mine is a couple of years old and not that model.
 
So, I've brought my problem to this great forum.
 
What I need to know is - where can I send my spray bar to have the nipple re soldered back in place? I think this will be the best option.
 
John.

Thanks Olly but I contacted Jenny at Just Engines yesterday. Unfortunately, they don't supply Enya engines and don't carry any spares.
 
I was going to attempt soldering it back myself, but I'd only make a pigs ear of it so I'm looking for a specialist to do it properly.

Is it a 2 stroke Enya 30?
 
My 2 stroke Enya 30 SS plain bearing has the same needle valve as the Enya 40SS plain bearing and a replacement part I bought some years back shows it also fits Enya 29 and 35.     It would be surprising if a needle valve is not avail.
 
You might easily find an Enya 40 SS secondhand to provide spare needle valve as they are more common than the 30SS.
 
Otherwise there must be someone in your club who is good at soldering -----just ensure you de-grease it properly first.

Thankyou Ken - I'll phone J D Haytree tomorrow. I've heard his name mentioned somewhere before in connection with other makes of engine.
 
Thankyou kc - yes it is an Enya 30 2 stroke. If I get no joy (highly unlikely..) with J D Haytree tomorrow, then I'll certainly be asking around the Club when we meet up on friday evening - that is if any of them are sober after returning from the Marburg Club in Germany (Twinned with our Club) 
 
Cheers,
John.

Having found the instruction sheet for both the Enya 30 and 40 I notice that the plain bearing models have the same needle valve but the BB models have different carb to the plain bearing. 
The SS  30BB also the SS 25BB and SS 30 Ring have G5.5  or 2 needle type while the plain bearing type have 'Normal Barrel type'
It looks as though 2 different carbs were fitted on the 25 BB  and 30BB models and that they were 5.5 mm rather than the 7mm of the 40BB. and some are 2 needle and some as in the drawing are single needle.
 
By all accounts John Haytree is the man for spares.  Please post a reply saying whether he is able to supply spares still.  Then we can all support his business when we need spares.

Hi kc - yeah, that was my problem when it came to try and order another spray bar. When I approached Steve Webb models, who are the Enya main distributors, they asked me if my 30BB was the 30TNBB ie, the twin needle model. They told me that the only 30BB they now stock was the TN model. So, I ordered the TN model spray bar to try it out. It is'nt the same though - being shorter in length.
 
J D Haytree sounds very promising. I found an advertisement of his in another magazine and according to that he services most main brands of model engines and has over 200 new engines in stock.
 
When I tried to contact him by phone yesterday though, I got a recorded message stating that he only takes business calls during normal hours on Mondays, Tuesdays and Wednesdays... He does not appear to have a web site either. So I'll have to wait until next Monday at the earliest to contact him.
 
I'll be attending the normal Club meeting tonight so I'll be asking around to find out if anyone has the soldering skills to re solder my nipple back in place over the weekend.
 
When I contact J D Haytree on Monday, I'll certainly post up here how I get on.
 
John.

Lets hope J D Haytree has the parts.
Does your spray bar look like the one in the leaflet on the SS 25BB exploded diagram, but with a longer  thread, about 14mm?  If so it may be the same as plain bearing 30 and 40’s.  The spare one I have is marked 29440F on the packet and the parts list for 25BB shows 294400F1 for the needle, but another number for the spray bar.
 
You did not describe the exact fault. My spare needle valve had (still has! ) the nipple loose from new and it was clearly a manufacturing fault due to poor soldering.(dry joint )  If yours is similar it is proof that such a fault originates with the manufacturer and should be rectified by the makers agent.  Maybe they should give you a new carb if they cannot supply spares.  If it is accident damage then you cannot expect this , but maybe……

However a couple of other ideas are


1 Make contact with your local model engineering club for someone to show you how to solder this type of thing. ( I reckon a micro blowlamp is better than a soldering iron. And soft solder only )

2.  Send an e-mail to Brian Winch for his ideas on the problem ( he must be always looking for things to put in his columns in RCME and Airborne (Australian mag )

3.  Compare your needle valve with other Enya 25, 30 or 40 to see if it is similar.

4. See if a remote needle valve could  be fitted ( i.e.  get the adaptor to fit your carb )
 

My Enya plain bearings have done hundreds and hundreds of flights without any spare parts, so it is worth repairing them if possible. Got to fly the SS40 this afternoon......

Well, I can finally report a great success. I phoned J D Haytree on Monday and explained my predicament with the broken fuel nipple etc...
 
In the end I was told that the best solution was to buy a complete Enya needle valve assembly  (£7 - 50p + p&p) which I did. The needle valve assembly arrived first thing Tuesday morning. Fantastic.
 
I found J D Haytree great people to deal with and would thoroughly recommend that you contact them with any engine spare part problem, atleast try them first.
 
kc - many thanks for all of your comments - I've taken them all on board, much food for thought. Greatly appreciated.
 
John.

John haytree has been operating as a solo run business in his lovely devon house and garden for donkeys years. I remeber once visiting his place a LONG time ago for some spares.... and as you have seen, he is excellent.

I don't understand why  Steve Webb the Enya importers could not identify and supply the spares when John Haytree has them in stock.   Why didnt Webb's arrange for Haytree to supply without all this fuss?
 
Perhaps the Moderator might ask Steve Webb to comment? 
 
Enya engines are excellent but their reputation will suffer if the spares situation is not as good as the other main engine makers.
