what is up with your master cylinder? i thought rhd mk1s had linkage to the left side of the engine bay? did later cars have the master cylinder like yours
Reg, I did some further reading, and you will be pleased to know that that electric thing under the pump does seem to advance, It does it by rapid switching on and off and varying the pulse rate or is it length I cannot remember which, but, clearly an overall average proportional thingy...
Whilst the pump was off and stipped last night I took some pictures so people might know what I'm on about however looking at it - I'd say that it retards not advances. You'll see when I post the picture but it is in essence a solenoid valve that sits in a gallery that delivers pressurised diesel to the retard side of the advance shuttle valve. All that it can seemingly do is bleed pressure away form the advance side of the shuttle and direct it to the other side.
I'll post pictures...

Nothing is up with my master cylinder - it's in the bin, complete with the awful linkage and pitiful servo.
What you have there is a bigger servo and master cylinder, moved back across the firewall and directly linked to the brake pedal. AND it's not some scene approved VAG manufactured 9" servo 22mm cylinder combo but a non-scene friendly FORD part (10" servo 25mm cylinder)
Such a novelty that have brakes that work.
Engine rebuilt with 2 notch
Pump rebuilt, this is standard AAZ with just a blanking plate over the advance piston
Thankfully the 1.6 timing shuttle is the same diameter as the AAZ one but it is slightly longer, the 1.6 cover is much deeper to allow for this so I swapped the lot.
It fired up and smoked worse than before. I wound in some more advance - no smoke, no clack.
