Link to small video clip of engine running, I still think a bit fast.
Opinions welcome.

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.

Just a speculative thought: on my engine the visible part of the
governor consists of a shaft emerging from the crankcase with a lever
clamped onto it. The wire link, with spring wound round it, goes from
the end of the lever to the butterfly valve on the carb. I imagine the
angle of that lever to its shaft is pretty critical so if it got
disturbed it while dismantling/re-assembling, that could affect the
speed setting. Is there any part of the governor mechanism inside the
crankcase that might have become misaligned?

Thanks Brian, I have since got a picture from `Briggs` showing the correct
layout so I now know that is correct.
Apparently where the other end of the spring locates (opposite from the
linkage end) its a case of bending the metal tab to reduce or increase the
tension on the spring.
having done this I still think its running fast. I am going to take a
video clip and some pictures and will post the links on here later, It
will be interesting to see if others think its running fast or not.
I have messed around with it that much even I am not sure any more.
