[Roadsters] Early SU Carbs

[Roy Haslett]

So I'm going through my parts today trying to get organized and remember what
I have.B  I came across an intake manifold and a set ofB  Carbs.B  However,
these carbs look different than what I have on my car currently and when I
turned them over it says SU on the bottoms?B  Also they bolt onto the manifold
with 4 bolts each.B  They also each have a small heat shield, not the one long
one that I am used to.B  Can anyone tell me anything about these?B  I think
they came off my car as stock from the original owner.B  Did Datsun use
English SU carbs until they made their own version?B  Thanks
Roy

Thanks for the Kudos & Ibm glad it worked. I was nervous I got the number
wrong or it might not have worked for your setup.
Maybe this could be added to
the 311.org techno info. I have other gems like this to add as well.

For
low windshield cars, the 520 (Not the 521 which is Metric) pickup truck single
brake master works great and it used to be less expensive through Beck Arnley.
Itbs vertical brake line output enables clearance of the stock Solex air
cleaner. (It fits between the Clutch & Brake masters. My car also has the 1x3
brake line distribution block once sold by Nissan Comp.

Hose Alternative for 1600's

In my search for an alternative molded lower
hose for my early 67 1600, Walt Peterson suggested an alternative where you
can get both upper and lower hoses out of one hose.B  I have tried it and
happy to report it worked very well.B  The hose is a Gates 21162 lower molded
hose, 1-1/4" ID.B  This hose has a sharp bend on one end that attaches to the
the water pump .B  The opposite end has a gentle bend which will become the
upper hose.B  Measuring from the gentle bend end, measure 9" up on the OUTSIDE
curveB of bend,B  cut the hose square and clean (I used a simple razor
knife).B  This cut off end is now your new upper hose.
Install the now shorter
lower hose at the radiator end first, do not tighten the clamp yet.B  Install
the other sharp curved end onto the water pump, again do not clamp down yet.B 
Now look down and check that you have clearance from the fan belt and
pulley.B  IfB  the hose is touching or too close for comfort all you need to
do is reach down and give the hose a little twist on the bottom end to the
right to create more space.B  That should do it.B  Now tighten those clamps.B 
The upper hose installs simply.B  It will go on either way, but try both
because one way fits better.B  I installed these on my stock 67 1600 with
stock radiator and shroud and stock thermostat housing.
I ordered the hose
from Amazon.com for 10 bucks and change (Pick Pro Parts is the vendor).
Not
too bad, huh?B  Two molded hoses for $10 +
B As a back up I also ordered Gates
hose 20900 Upper Molded Hose in case the cut off piece didn't work.B  This
fits perfectly as well, however, it is a 1-1/2" ID so it requires more
clamping to fit tight.B  Cost was about $6.
While you are at it get a new
fanbelt, Gates 7395, from the same vendor.B  This is the goodB  toothed
belt.B  I think it was only $7.

Good Luck!
