Carburetor SU HS6 Set up for Land rover series Part 1.

In search for the best replacement of original Zenith carb, I found few alternatives, again Internet is helping me a lot. In the spirit of sharing, I would like to share my carburetor set up. I have written: possibly the best carburetor for land rover series few days ago, so I will not cover why I choose SU (skinner union) carb. Here I will explain about the set up, lets start…

Installation is the most complicated one

1. It requires you to fabricate the manifold / bracket to attach SU carb to your inlet manifold
2. It needs us to alter the current linkage (to pedal) set up
3. SU HS6 comes with many type: Left fuel bowl, right fuel bowl, 90* (up right position) and 30* (slightly tilted like in V8 rover)

Those three combination of complexity need us to think, the best placement for the carb. Is it facing to engine, is facing the bulk head or is it facing the radiator fan etc.. Undeterred by this complexity, I go ahead and by second hand SU HS6 and hell broke loose.. :)

Installation: The relatively easy part is buying… I am lucky to get New Old Stock SU HS6 quite cheaply,  so that is good..

Now lets make the manifold / bracket or anything you called to attach the carb to inlet manifold. The easiest way is go to a garage that have access on lathe and ask them to set it up for you. for my case I have to go to two different special garage, one is to make the base (two bases as you can see here: one goes to carb and one goes to manifold) the the other garage (exhaust specialist) to make the connection pipe and set it up in the landy. Here is the manifold ready to be installed.

And finally here is the installed carb… Picture explain better than word.. :)

With this set up I still retain part on the throttle linkage, just in case if I want to change it to zenith again, I still have the parts in there… Hence it installed away from bulkhead and closer to radiator fan. The oil bath filter is still there, although currently it is redundant… but yes you can use the oil bath filter again if you will cross Sahara desert… :)

So that’s all folks… if you have question please ask down below… stay tuned for part two I will talk about setting up the needle, jetting and spring and how it different with Zenith… see you later..
