Listers,
I'd like to confirm the number of insulating blocks / distance pieces
(AEC2126) fitted around the tri-carb heat shield, after engine 29E-928.
In the 2018 version of the Concours Guidelines, on the bottom of page
35, it states: "Heat shields for the 29E engine; early cars have an
inner asbestos shield attached in the same manner as the 29D. Later cars
after 29E-H928 had an inner and outer asbestos shield requiring
carburetor spacers. There is a thick spacer on each side of the heat
shield: one next to the manifold and another between the heat shield and
carburetter."
The service parts list (AKD1151 5th ed.) shows that the heat shield part
number did change at engine 29E-929. It also shows the addition of the
distance pieces at the same point. But the quantity is only three; not six.
If there weren't any distance pieces used on the early 29E engine, then
I could see where a distance piece between the heat shield and the
carburetter would be required to space the carb out the same amount as
the outer asbestos shield. Don't know why the distance pieces would
also be needed between the intake manifold and the heat shield. Unless
there was another issue being addressed?
Have also sent an email to Roger Moment.
Cheers,
Bob Haskell
