When i've done it before, i took the ht lead off that connects the coil and the dizzy, remove the lead completely, no problems.
Then also remove the fuel pump fuse.

Why the fuel pump fuse, does this stop the car from becoming flooded?

Yar.
If you don't take out the fuel pump fuse then you will get rather high compression, as the cylinders will flood with fuel  :D

Right good news here are the compression test results (I am working from left to right as I don't know which are which)

Cylinder1: 185 psi
Cylinder2: 190 psi
Cylinder3: 185 psi
Cylinder4: 185 psi

The second one was slightly higher as you can see, but not by much.

So what next? If this is a good result on a car that has done 183000 miles, where else should I look for the burning oil? remember it only appears when the engine is up to running temp and is idling, i can drive for 10 minutes or 2 hours, pull up and let the car idle, at first the exhuast is clear then after about 1 minute the smoke apears, not bellowing out but enough.

Any advice would be much appreciated as always

Compressions are bang on, oil consumption is probably from the valve stem seals.

Have you cleaned the breather hoses?
