having messed about with it a bit more I am still at a loss as to how to
locate the springs...

I have a B&S engine with two springs, one of which is much finer than
the other. The heavier spring is the linkage between the throttle cable
and the choke/main valve, the finer spring doubles up the linkage
between the crankcase governor and the butterfly valve which it
controls. Its ends just hook into the same holes as the wire link
itself. Because there is a good deal of looseness in the wire linkage,
the fine spring can act as a damper so that the governing action isn't
jerky --just like Gary said!

I now have the springs correctly located but engine still running fast.
Going to take the cover off and have a look at the complete assembly,
everything appears to be free and not sticking so the only thing I can think
of is the fan blades on the flywheel are not producing enough` blow` to push
the governor which is unlikely or the spring on the linkage is to `tense`
and therefore not allowing the governor to be blown back and operating the
carb valve.
I might try and put the likage on the other way round as this should reduce
the tension on the spring, worth a try anyway.
