I can see how the operation of that valve would be massively affected by the condition of the hose that connects onto it- the hose on this carb is perished at both ends. I tested the float and it holds air and doesn’t leak.

I have a tool that fits the mixture adjustment on the bottom, but I don’t have a tool that will fit the... not sure what it’s called, the float bowl inlet jet in the float bowl that keeps the float bowl full but not overfull. It’d have to be an extremely thin walled socket to remove it as it’s close to the edge of the floatbowl.

The main needle is clearly bent, so I’m curious how the car this came from ran...

I think I have enough spares to at least remove the current carb and look at it.

Cheers,

So- dashpot, how much oil?

And is there a guide online anywhere to tuning these carbs?

Is the needle really bent, or is it a spring loaded "biased" needle?
