28/36 DCD2 Weber choke delete

[Mr.Mk1]

Hey homies,

I’ve got an old Townace that’s got a haunted carb.

it came with a 28/36 DCD2 Weber in decent order so ive rammed that on this afternoon.

It fired right up but it’s revving its tits off and all adjustments are set generically. The idle screw isn’t yet touching.

I don’t need a choke, and I’ve found that putting my finger over these holes, it brings revs right down to an acceptable idle speed.

Has anyone assholed the choke setup? Can I just seal these holes with a wee block off plate? About to do 600k open road mission so any advice on what the specific holes are for or how I can lock/block the choke would be much appreciated! 

 

 

Despite being a super common carb I can’t find the info I want..

that hole should have a spring and a piston in it that the choke lever arm acts on, that brass ring on top is the retainer for that stuff

Im sure you can figure out away to block it off if the piston is missing, (remake piston with jbweld?, jam a bolt covered in tape in?)

If the piston is in there maybe the choke arm isnt set up quite right and not hooking on the piston properly? By default the spring should be pushing it down (Off)

Diagram C on p551 shows how the piston should sit with the choke off (the term in the book is 'out') , basically blocking all the orifices off

Diagram C shows what you are trying to do

You sir, are a gentleman of the highest order!

Thanks heaps for that, I’ll attack it tomorrow with new energy.

It’s a pretty funny wee van that I brought cheap pulled down for rust and paint.. did those in short order and whacked on some aliexpress motorhome graphics and some hoarded banners from work then did some camping and sightseeing missions..just sucks pouring fuel through it.
