Single Stromberg to SU B20A
 

Hi Folks,

I am looking to alternatives to the Stromberg 175 which I found very difficult to adjust. After being with an “expert” the carb is a mess and I need to completely rebuild it. The only good bit left is the core.
Over the last 2 Years I have never been happy with it. Maybe time to replace it?
I read here the only straight swap is the SU HS-6.
I understand the SU is easier to work with and more reliable? I also remember I have read the SU was the Carb used in 140 Taxi?

There are Weber downdraft conversion kits

A little more complicated if you have a one piece intake and exhaust manifold.

The Stromberg works the same as the SU and is one of the simplest carbs and easy to adjust and tune. Your easiest and best route is to rebuild the carb. What model Stromberg have you got? Post up some pics. I'd fit a Stromberg 175cd2se, really nice carb. But you need to fit the jet conversion so you can adjust the fuel mixture; https://www.southerncarbs.co.uk/onli...rsion-Kit.html

Hi

Thanks folks, I have now jumped on a offer to get a NOS SU, which I have taken immediately.
What do I need to fit it now? do I need a backplate?
