We’re going to rebuild the carb as a starting point- but he also has a complete Stromberg as a spare.
Given that the rebuild kit is the same and we’re in exactly the same starting point with either, is there any reason to pick one over the other?
Cheers

The Stromberg 175CD carb is said to be temperamental to set up and tune,
its not true people just dont know how to do it correctly
The Stromberg carb was back in the early '70s considered a performance upgrade over SU carbs the good thing is they are easy to set up right
with all the parts available new from Burlin fuel systems,
My advice is to only use a genuine Stromberg Diaphragm
the cheap ones from ebay etc are not the correct type of rubber and certainly not the correct stiffness or flexibility
Be sure to replace the float bowl gasket every time you remove it and Always set the float height correctly, you will get fuel blow back an spitting if its not right, flooding and over rich mixture etc
The Pierberg carb is German made and although very similar in operation its just difficult to get parts cheaply and is more difficult to service
Go for the Stromberg 175 CD2 type its the closest to fuel injection a carburettor gets.
