[928uk] Timing issue - 83 "S"

[John Constantine]

Thanks Paul,

Some valuable tips - which make sense. I have had the strobe connected at
the cap - mistake number 1.

The "Y" pice that goes to brake servo/shoe. Not being infront of the car
it's hard to say which is off. However the one side of the Y runs from the
right hand side of the plenum back underneat the plenum to the left hand
side of the engine bay - that one is connected it's the other one that
isn't. - Any idea which it is from that description? And where is the
"shoe"?

Also plugging the Vaccum lines - makes sense again now you say it. I haven;t
been thinking very clearly this weekend, so all this advice is appreciated.

Thanks again,

JC
