New Concentric MK1s from Wassell

Postby johnmead » Fri Nov 23, 2012 4:50 pm

It looks like Wassell is making and selling it's own MK1 Concentrics.

Well Mark, I didn’t time it, but to model the carb I need to have it in my hand. I started this in 2006 when a friend gave me a float bowl with drain plug to replace the plain one that was fitted as standard. The carb has been working on the bike ever since. Recently, I picked up an old carb at a jumble and so was able to finish the model off. Working about four hours each evening. It went from jumble to Youtube in five days, but I already had the bowl model.
Once you have the model you can get things like this virtually free (of time cost)... (float bowl part number is wrong)

While this is an old thread the subject remains valid.
Has anyone else bought/fitted/experienced these Wassell carburettors?

I fitted a pair to a motorcycle of another, but closely related make, and have experienced flooding problems with both. The ticklers can become stiff to operate, jam and then when eventually released the petrol continues to pee out of the carb as though the float has jammed down. It is an intermittent fault and I've looked for the usual gasket interference and float interference issues with no obvious problems.

My question to this forum is: Are my experiences unique or are they typical of Wassell carbs?

Cheers
Bill

Bill, a year or so back a mate had a brand new pair "given" to him for a very cheap price, to use on his Thruxton Bonnie he was rebuilding (God knows why - probably the cheap price :roll: ). He couldn't get them to run right (and if memory serves, probably similar problems to you). So he went to Burlens and got a pair of proper Amal Concentrics. He has not looked back and admits he should have gone down that route in the first place :thumb

That's a bit unfair Chris, you'll find good and bad with most suppliers. A lot of NOS only exists because it never made it to the scrap bin. There are only two main suppliers having things manufactured. And yes some can be awful, worse still they won't pull the stock when you point out the problem.
Back on topic. I do prefer the Salisbury Amal carbs if you can get them to supply. They seem to have constant trouble with the manufactures of the bits. That said the Wassell ones I have setup have been fine too.
Just remember Amal have been made in many country's over the years. Spain, India, Germany, England possibly again around 2002 and I think the original name is Swedish. At the end of the day it has to do the job intended and at an affordable price.

That's why I would buy/use an Amal from Burlens and not a Wassell

and where is the mileage in an item that 'don't do the job'? being cheap just don't cut it with me, its got to work or you have just blown money and time.

I have fitted 'Salisbury Concentrics, premier grade' to three bikes in the last year and generally been very happy with the results, the only glitches being:

- when I called Amal direct their attitude was truely awful, I then spoke to Surrey Cycles who were the exact opposite. I only buy from SC now
- the last one I bought had some minor damage to the top of the slide that caused it to stick when fully opened. It looked as if the Slide had been dropped at some point, it was easy to sort with a fine file so I didn't report the fault to SC.

I let Ian Hingley have my super reliable Mikuni for the IHO and fitted a Salisbury Amal to my B44, the bike still starts easily and has noticeably better top end than before. I conclude that a new Amal is as good as anything for a road bike.

Amal is short for Amalgamated, it was a collection of UK carb makers that merged into one, nothing to do with Amal the town in Sweden where I visited for 2 days to visit the Driveshaft plant there :ban .

This site is a mine of information :smile:
So where does Amal/SEM fit into this mix?

Amalgamated Carburetters
‎‎
Amalgamated Carburetters of Holford Works, Perry Barr were makers of carburetters, supplied under the trademark Amal and others. Amal were the major suppliers of carburettors to the British motorcycle industry for a long time; their products were used by large manufacturers such as BSA and AMC.
1926 Amac was owned by Nobel Industries which became part of ICI this year.
1927 Public company formed: Amalgamated Carburetters Ltd to bring together 3 manufacturers Brown and Barlow, Amac and C. Binks (1920) Ltd for better utilisation of their resources[1], headquartered at the Brown and Barlow factory.
1930 Application to amend patent granted to Brown and Barlow
1931 Name changed to Amal Ltd.
1937 Manufacturers of accessories. "Amal" Carburetters, Pumps etc. [2]
1939 See Aircraft Industry Suppliers
1940 Part of ICI Metals Division.
1943 Amal was moved into new premises due to fire in December 1943.
1956 Amal Ltd declared its results and dividend; was said to be controlled by ICI[3]
With the decline of the British motorcycle industry, the demand for AMAL carburetters fell[4].
1961 Authorised capital of £320,000 and employed 600 persons[5]
1961 Light precision engineers specialising in carburettors and controls for motor cycle industry, bonnet fasteners, dashboard controls, petrol filters and fuel pumps for motor vehicles. Ball and roller joints, flame traps, bunsen burners, gas injectors, jets and non-returns valves for the gas world-wide. [6]
1963 Amal Ltd, a subsidiary of ICI, reported a loss larger than the previous year[7].
1964 The outstanding shares were acquired by IMI[8].
1965 Part of IMI[9].
1965 Supplied parts to General Dynamics for the conversion of the Dart Convair to using Rolls-Royce turbo-prop engines[10].
1968 Member of IMI Group[11].
1993 Sold to Grosvenor Works of North London - a supplier of fuel system components. Under Grosvenor some of the more popular obsolete ranges were re-manufactured.
In 2003 the business was sold to Burlen Fuel Systems, a company that also produces SU, Solex and Zenith, three other "classic" carburettor ranges. See Burlen website [12]
The carburettors are still produced by their current owner Burlen Fuel Systems as spares for the classic motorcycle market. The AMAL and AMAC trademarks now cover a range of products including carburettors (principally but not exclusively for motorcycle engines), controls (brake and clutch levers, cables, etc.), fuel lift pumps, gas jets and burner devices as well as gas safety valves.

I've always wondered about the name Amal.
But not half as much as the name Wassell! :shock:

Amal and Wassell:
I bought a NOS black plastic twist grip in old blue and white Wassell box.
Using compressed air to remove the Wassell branded Doherty style grip, the grip instantly ballooned and split along a seam.

Cleaning off the old cloth tape which had been carelessly wrapped around the plastic (polypropylene) twist tube I was surprised to find the AMAL trade mark which is also inside the black plastic body. The cable adjuster is alloy and the dust excluder poly-something, not perishable rubber.
It seams only the trashy rubber grips and packaging were Wassell. The robust, almost weightless Amal twist grip works smoothly and without rattling on the handle bar.

Which all goes to show you can't judge a box by it's contents.
