1950 Triumph 3T

[den]

Hi All
I have a trimumph 3T 1950.Does anyone out there know which model Carb this bike should have i have been told it was a Amal 275 pre monobloc is this correct? and if so where can i find one? The carb on the bike at the moment is very worn and i cant get the engine to idle and in any case i do not believe it bis original as it is a monobloc and is definately different to the one pictured in the ownwers manual.
I would be grateful for any advice.

Hi Dennis

In 1950 it was most likely a pre monoblock that was fitted, these people will know exactly which one you need and how to jet it for your bike.

Thanks Revband i will give them a try.

They're always on ebay, but you don't know how worn they are.

You can just buy a new carb direct from the manufacturers if you wish. You can contact them direct on their website, www.amalcarb.co.uk
Why muck about with a third party when the manufacturer is willing to deal direct.
Cheers,

Hi 33d6

If you have ever tried to deal direct with Burlen you will know that the people you can get to speak to have very little technical knowledge, unless you know exactly what you need regarding jetting ETC, forget it because they don't have a clue.

Also from Surrey Cycles the amount you pay extra is very small and you will have it next day and not next month.

Oh yes....Burlen = crap service (surprisingly, for a manufacturer) and
Surrey Cycles = very good.

I wouldn't use an Ebay carb, same as I consider any old carb that comes with a project as scrap/for rebuild, and they usually are.

Rather like tyres, batteries cables and wheel bearings, you may get away with reuse, but new always gives a much nicer ride.

Little point in spending £XXXX on a project to then let it down by scrimping on parts like these.

funny old world, I live 20 mins from Burlen, so when ever I want something i call in and have never found them anything other than helpful or knowledgable.
Surrey cycles on the other hand............

Thanks for this everyone
I did try Amal but was told that the carb i needed was not manufactured any more. I will give Surrey Motorcycles a call

Thanks again.

Hi Dennis

That's what I mean about Burlen, they make the carb and don't even know, take a look at their web site.

http://www.amalcarb.co.uk/

You should do better with S Cycles.

[yebbut]

possibly they get fed up with dealing with people that don't know what they want?

no offence intended Den, just the voice of  past bike trade experience

[den]

No offence taken but it was obvious to me that the carb fitted to the bike was not the original as it is a monoblock as i have an original owners manual which shows a different type (i now know it is a 275 pre monoblock)
They were helpful in as much as i now know what i need although s c did confirm that the are not produced now and suggested that i should either fit  276 which is available or a 376 monoblock which is less expensive £160.00 ish. I will check the web site as suggested.
Clear as mud!

[Revband]

Probably as yebbut says, which is a good reason to talk to a supplier who is more prepared to help the majority of us who like to be sure they get the correct item first time.

Strangely the Burlen web site still lists the 275!!!.

It all depends how much you want the bike to look original, to be fair the monoblock is probably the better carb of the two, the monoblock will not physically fit on some bikes, but it must be OK on yours as you have one fitted, the other thing to be aware of is that the jetting for a 376 will be different to the 275

[yebbut]

agreed, I would stick to a mono bloc unless you are a fanatic pot chaser and rivet counter. they are a better carb all round than the 275 or the later concentric.

When I was in Burlen a couple weeks back they had  pre monobloc carbs on display and no mention of them being no longer availiable, after all new carbs is their business, they do the lot from tiny amals up to carbs for Merlin engines.
The only version they dont do is the vertical flange type for Douglas.

All I can think of is that they are either out of stock, after all they don't make them one at a time, or you got the work experience muppet on dinner break.

If you want to get a 276 you could always send me the details and  specs and I will call in when passing in a week or so.

EDIT,

re the 275 the penny has just dropped, use a 276 as  long as the bore and jetting are the same it will make no the difference between the two carbs is just detail

Since i am not showing the bike but riding it i think the monoblock sounds like the best bet.

Thanks for all the help.
