Carburettor problems.

[David Stepney]

Are the two bodies both '7' matched ones, Ruairidh, that just don't behave well when mixed, or is one of these of Davids an '8' carb with larger choke?

Jon,

Both my carb bodies have '7' stamped in the carb to manifold flange. As Ruairidh pointed out, they are both different patterns and it is clear now that i had the wrong float bowl for the carb.

Now that the carburettor is now sorted, I am going to do another fuel consumption check. If I get  into the late thirties around here I shall be happy.

Thank you Bob for the comments you make in this regard. And yes, the car has been clocked at 51.6 mph using one of those clever GPS devices that cyclist use.
