Will do
I'm going for a test drive in a minute anyway.
I bet my handbrake is rusted on after two weeks standing...

The car had another stutter today on the way to the supermarket, is there anything else I can do to check?

Yes, that does look like an attempt at a home-made suppressor. I would be tempted to take it off and see if that makes any difference.

Certainly looks like a suppressor - if it's any good - there should be no sparks !

It still sparks... but smaller sparks

I'm hoping so
What gap should the points have? I can't find it in the manual.

Normally - they sit closed. When power is applied they are pulled open by the drag of the solenoid coil, and then flip closed again as the coil relaxes. So - the gap will really depend on the stroke of the solenoid - which is set by however many turns you screw the point set onto the armature shaft.

I know its probably too late for you now but each time I have changed points on su pumps I carefully count the number of turn to get the old ones off the armature shaft. Then screw the new ones on by the same number,not had to reset the points gap using this method,Seems to work out about right each time.

Does the power go to the fuel pump when ignition is switched on?
I have no power for some reason...
I don`t fully understand the need for points...

You are saying that you don´t see the point

You certainly need power to the pump!
The pump is a linear solenoid + a spring and a diaphragm
The solenoid pushes against a spring when the power is on. When the slenoid has compressed the spring, the points move so the power should turn off. The spring pushes against a diaphragm which pushes the fuel to the carb.
Therefore when no fuel is flowing (when carb is full) the spring stays compressed and the points stay open - so no electricity is used. When the fuel flows the spring moves and the points close and the cycle starts again.

Now I do ,clever things and it has burst into life...
Thanks for the clever answer Ray...
