I find a old engine with some "problems", a Webra Record 1.5 diesel.
There for I am surging for a exploded view so I can make new components.
A specialy the reculated needle is wat I want to make.

TIA, Rob

This engine?

Trolling around the web these come up.

Can't help you with an exploded view, but here are some infos about the Webra "Rekord":

There was 3 versions of that model over the years:

Being in europe it shouln't be too hard to find parts for it as it was produced in large number in the 50's and 60's!

Thanks, but it's this engine.
I surf all most a week over the net, but I can't find anything I can use.

What is it that you are after?
There is no exploded view in the manual but the needle assembly is very simple.

I would that Dave Owen would be the man here - he goes by the name of Sabre 250 on the Barton Forum.

The needle you show on the engine is not the needle on the box.
I need some values, and holes into the engine, to make a needle.

Please post an image of what you need.
If you have everything but the actual needle then just trial fit a piece of music wire and make a tapered tip on it. The hard part will be to make the threads on the brass part, they are usually a fine thread. The needle on the engine above is the standard needle of the time, so it is the same as on their larger engines.

Same 1.5cc engine, but with a RC-needle.
Not only more or les petrol, but also mor or les air.
I want to know the construction and values of the parts.

It is just a regular rotating throttle barrel. I doubt you'll be find any exploded schemes with all the dimensions in it. The exploded views usually only shows the design and part numbers.

If you have the special crank-case for the RC model, you can make a throttle barrel to fit it. If you have the more common CL version you can instead put a regular carb (from an Enya 09 for instance) and use the holes from the CL spraybar to put the retaining screws through.

The engine I showed above has a simple choke above the needle (stock Webra parts), and that sort of works too but does alter the fuel ratio a lot.

A 45 years ago, it was my first engine.
My dad buy a rotating throttle needle for this engine.
The old needle must be removed, the needle connecting holes drill......x-mm......ready.

Now I get from a friend his old engine, but there is no rotating throttle on it.
It's no problem to make it, but I don't know the parts I need.....to long ago

So why not buy a throttle for say a small PAW diesel and fit it?

I like the original trottle and the air inlet of the Webra is not a straight pipe.

There are in fact four (4) versions of the 1.5 Webra Rekord.
First in 1952 with a blue head and radial mount only.
Second in 1954 with a red head and both radial and beam mounts.......You need to file away part of the radial mount to use the beam mounts. Pic of that one on this thread.
Third in 1959 with a red head and beam mount only. Pic of that one on this thread. It calls it 1956, but that's incorrect.
Fourth one in 1964 with all alloy look......no colour, and beam mount.

Until I just contacted my Swedish friend, a Webra officiando, I did not know of the third version, and it saying it was 1956 confused me, as I have had several of the second version. And great motors they are. I have two in Freeflight models here now that start well and run hard.

It looks like a Silver Swallow inside , could the Chinese have got one and copied it ?

Well yes, but so did so many other diesel engines from that time.

Hi,
Hopefully these will help you!

If you still have original needle and pipe with lock spring and two nut, these should be usable with throttle barrel. The felt washer is necessary too!

I have done this to Webra Winner, which is quite similar as Record. All the important measurements are in mm and as accurate as possible from my own Record engine.

Only the throttle arm is somewhat draft, but I think it is adequate this way.

Best Rgds,

Whoa, I though that there was a snowballs chance in hell of finding that information and yet ........... here it is!

Well done sjhh57.

Hello, how well does the throttle work on the Winner and the Rekord?
I have those engines and will convert one of each with the help of your drawing, thanks a lot.

Hi,
So far I have test only the Record and the throttle works pretty fine. See this (not mine though):

http://www.youtube.com/watch?v=r3fdZ...eature=related

I have couple of Winners and it seems that there are small differences in throttle barrel: instead of single venturi there is also one

about two millimeter diameter hole and one millimeter hole on sides for low rpm. These are drilled to 90 degrees compared to main venturi. So when the throttle is closed,

there is that smaller "venturi" for somewhat fixed idle. Also the throttle arm is positioned as mirror image compared to Record.

If you have crankcase for C/L without hole for throttle barrel, you should be very careful while drilling this. Also check

all the measurements carefully while doing the metal work - f.ex. venturi is not necessary just in center point of the throttle barrel (= left/ right direction - I have noticed that

there are minor differences between crankcase castings).

Originally the throttle arm was fixed to barrel by pressed collar, but I also soldered it to correct position because I didn't really get tight enough joint without this.

I will post here some pics later to give better idea about the Winner throttle arrangements.

Best Rgds,

Some pictures. On the last picture there are Winner throttle arm on left and Record on right side. Record is more sophisticated, because a small "tooth" on arm could be tilted sideward to adjust idle. This is not working similar way on Winner.

Is there really a blue head Webra Rekord with both radial and beam mounts? Have never seen or heard of one before.

This one along with the usual red head is on USA eBay at the moment.

I've seen non red headed ones for sale before-they've tended towards a grey colour-perhaps originally a dark blue that faded? The ones I've seen have had parallel finned heads.Certainly the original red ones fade to a pink with time, so it is not impossible..........

Well yes, was interested in these two. Who now is interested?

It's all great information and I gone rebuild one of the two Webra's I have with a new reculate needle.
I have make some new components, like a new cilinder, piston and pressure head for one of the engines.
The engine runs like new but I'm missing still a exhaust and the needle, it belongs to the engine.
