[T3] do the late 73 T-3 fuel injected distributors have thetiming retard ?

Sorry to continue the myth, if it is a myth, but someone on here thought to
check the timing with the light on #1 lead, and then compared it with timing
on #3 and said he did indeed find retardation on #3.   It's easy enough to
do that, but I've never remembered to check it yet.  Since the reason I've
heard (only hearsay) is to do with the oil-cooler position, I don't see why
it wouldn't apply to all Type 3s if it applied to any.  Type 1 upright
engines have a different position for the oil cooler.  Later ones had a
'doghouse' arrangement to minimise the blanking effect of the oil cooler on

Another job to do some time - sooner the better in case I'm spreading false
rumours.  It's a good argument to persuade owners off 009 distributors. ;-)

a pertronix I suppose that does not exist. I always thought it was only on
T-1's or older VW's. 

No, and with the Pertronix this would be gone even if it had started out
with retarded #3 timing. There's a memo from Bosch about which distributors
came with the retarded #3 and I don't think it includes any Type 3
distributors. Of course, there might be a later memo that I don't have.

air flow to cyl #3 is impared . I thought the result of  clogged cooler fins
was over heating oil only since the cooler is above the cylinders and has
it's own exit out the fire wall tin on the left side above the trans. Mine
has the super cooling covers around the bottom of the cylinders that came
stock on late T-3 1600 engines. 

You're right, the oil cooler air has it's own exit. So if the cooler fins
are clogged this "only" prevents cooling of the oil.
