This is the pancake piece on the side of the distributor - pictured here.

I've been trying to replace mine (1984 1.9 DG) but I've been struggling.

A couple of HT leads off and remove the dizzy cap - easy no probs.
Removing the rotor arm and dust cap beneath - again no probs.
Next, removing the circlip holding the next piece onto the shaft - a little awkward - (even borrowing a circlip remover) but done all the same.

The next bit.
Haynes say use 2 screw drivers to remove the next part out of the dizzy. I gently tried to do this by trying to lever it off from both sides, but it didn't slide up the shaft of the dizzy as I'd expect. It did seem do extract the shaft a little though (worrying for someone that has limited knowledge).
Am I being too gentle with removing this part? (Just don't want to break the dizzy) that's all.

Any help appreciated.

no need to dismantle the disi, just unscrew the vac unit mounting plate from the side of the disi and lift the bar off the tab pin and the vac unit comes away, refit is the opposite just locate the bar with the hole in it over the tab pin and locate the whole unit and refit the screws, test by sucking on it and observe cam plate advance

Aidan, thanks for this. Shall be giving it a go this evening. Is it easy to locate the bar over the tab pin? Surely I won't be able to see what I am doing with the inner workings of the dizzy in the way?

Just to close the loop on this one.

It was as easy as Aidan stated. A short screw driver helps remove the screws from the old vacuum unit. Locating the rod inside the dizzy seemed to be straight forward also.

Took the van for a short test drive. Seems to have more power lower down now - especially noticable when puling away from junctions. Still think I have a slight hesitation though and when going downhill foot off the accelerator there is still a slight popping.

Carb clean is next on the list!

popping on the overrun is a little air leak...

Thanks. Have purchased new gaskets for the carb so hoping I find the hole in the old ones.

OK
check the hoses are good and the servo hose from the manifold is air tight
