Hi

 

My name is Steffen and I am located in Hesse, Germany.

 

One year ago I bought an 72` Mini MKIII with a standard 998cc engine (36 hp). It cames with a twin stromberg 125 cd carb on a Alexander manifold. 

 

The carbs now are ultra sonic cleanded, have new gasket, diaphragms and pancake air filters. The car is still in restoration...

 

 

I have a few questions: Is a twin 1.25 to big for such a small A-Series engine? 

If not - what type of needles do in need? There are still needles in the carb but I dont know the size - its not printed on the needles... Were can I get those needles or rather a set of it? 

 

Finally: The carbs have fixed needles but adjutable stocks (i dont know the right english word for that) on the bottom of the carb. Do i still need different needles or can i adjust the carbs with the stocks in an wide range?

 

Sorry my english is not so good but I hope you understand my questions.

 

Best regards

Steffen

Hi Steffen,

 

Sorry my German is worse than your English!

 

I don't have an answer to your question, however you will find a useful computer tool here;-

if you click on the 'Needle Selection Tool' it will download a program that will help you with Stromberg Carbs fitted to Minis. You will also need LIBREOFFICE to make it all work.

which part of Hesse? I am just across the river R-P

Stromberg carbs were nearly always standard fitting to Triumph cars in the late 60's and 70's so someone like Rimmers might help. I think Saab used them for a while as well.

Twin 1.25 inch carbs are good size for a 998.

 

The original Coopers all used twin HS2 carbs until 1971. These were also 1.25 inch.
