  Also... the throttle goes downwards - so does that mean I need a bottom linkage kit?

    James,
    
    The top mounted linkage pushes downwards, the bottom linkage pulls.
    
    You say you are fitting a single Weber - make sure that any linkage that you get mounts onto one carb only - a lot of them have the operating lever one one carb and the cable guides fitted to the next carb - no good in your case.

      James,
      If you have to buy new the try these people...
      
      http://www.fuelsystem.co.uk/new_page_13.htm
      
      I'm told thet supply to the major retailers and their linkeages are only &163;45 The illustrations clearly make David's point.
      
      Also, they are five minutes away from where I work

        Cheers NiG & Dave...
        
        I don't *have* to buy new - but having looked on ebay just now...
        
        http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ca...
        
        Cheaper to buy new it seems... unless I find anyone selling a s/h one...
        
        Oh yeah - another question; am I going to be able to run this with just my normal mechanical fuel pump? or am I going to have to get a regulator to go with it? electric fuel pump?

          Have just finished making mine James.
          Basically sheet steel mounted on the front of the carb where the choke mech used to reside and extended over the throttle linkage. A small lever carefully welded to extend the throttle arm forward converts it to a 'pull-up' system.
          Oh for a digital camera not to mention the tech 'know-how' to use one.
          You young'un are so lucky, in my day............zzzzzzzzzzz

            Sounds an interesting design - how much are you charging for them then?
            
            Is it worth taking the choke mechanism out? I've heard they're rubbish on Webers...

              I've not spoken to anyone who actually uses the choke on Webers. Mine is for twins, but a 'mirror' image would be easy enough. If desperate I could probably post you an origami template.

                I won't bother connecting up the choke then... who needs it when your right foot pumps fuel anyway...
                
                I'm still trying to get to grips with the way the carb works anyway... oh for the simplicity of SUs!
                
                Origami... probably be more use to me than actually trying to make it anyway!... I'll pass I think Keith... I could probably engineer something - but having no welder is a pain (I actually do have some skill with an arc welder too!)
                
                Actually - looking at the bottom of this carb I can see how I could make something up now... using the bottom cover to hold a piece of sheet metal... hmmm...

                  Having run both double Webers and triple Webers over a period of years on both 4 and 6 cylinder Triumphs, I have determined that you will need an electric fuel pump, (I use Facet Silver Top), and that you should also use a MALPASSI Fuel Regulator set to NO MORE than 5 psi, (from Southern Carburettors in Wimbledon).
                  
                  The throttle linkages from Moss are a piece of crap, so don't waste you money there.
                  
                  Mine is from TWM in the USA with some parts from Southern Carburettors in Wimbledon, (the stainless steel ball joints, replacing the nasty nylon ones)
                  
                  Use an inline fuel filter, (the glass kind with removable nylon filter, not the paper sealed in plastic kind), between the tank and the pump, and another one in the engine bay between the pump and the Weber.
                  
                  If your Webers are 2nd hand, as were mine, you should completely disassemble them and dunk them completely in carburettor cleaning fluid, (the yellow evil smelling stuff), for about three hours each, before flushing out with copious quantities of water, then drying out thoroughly before re-assembly.
                  
                  Don't use Thackery washers, but instead use the cup washers and rubber grommet inserts.
                  
                  Don't even bother with the choke mechanism on the Webers, just ignore them.
                  
                  Finally, dump the Lucas/AC Delco distributor and get one of the really decent Mallory distributors, (as sold by Mallory for the MG Midget 1500), and use a Petronix kit in there, as these work with Webers particularly well.
                  
                  Best Regards
                  
                  Any questions feel free to email me directly as I don't get to look at the TSSC site very often.

        Well I got my linkage through today... and I think I need a different throttle lever on the carb.
        
        Anyone got a spare?

          That's that same one as I use... the linkeage is there - I can see it hiding behind the big triangular thorrtle link. You just need to join them together.
