Great article on the installation of 2 x 40 DCOE carbs

I race a 2002 but updated the engine to an S14 so solved all problems of timing, fuel and air controls.

 

However I have just purchased a 73 2002 roundie which was an unfinished project.

The beast takes time to start and does not run at all well.

 

The previous owner installed an overhauled M10 engine from an E21  and added 2 x 40DCOE/32 carbs from an Alfa GTV 1750cc.

He blanked off the mechanical fuel pump and fitted an electric format.

 

Can anyone tell me what the correct jetting should be for these carbs on this motor?

correct jets are going to be the ones you tune it to run best with.  each engine is different.  use some of the guides as a starting point, then change them to get it running correctly (using your afr gauge).

The answer to this question might be buried somewhere in the many postings already here but I didn't see it.  What about the throttle cable itself coming from the accelerator pedal.  I've got the overhead webers now that haver the mechanical rod which links to the side of the overhead carb (32/36), but I understand I'll need to replace all of that with a cable pull system to move the throttle on the dual webers (and linkage).  Are there some tips or guidance to set that part up?

I use a Lokar cable to connect a good rod linkage to the pedal box.  It needs support arms at the pedal box and up at the carb for the cable sheath.

Andrew, that’s a really clean looking setup. Is that an Ireland intake manifold, linkage kit too?

Yes, it is an Ireland manifold.  No, it is not a IE/Redline linkage.

 

Here is another recent client build..... IE manifold (port matched), Adams Fuel Rail and Cold Start Block Off's, 40's, Longer velocity stacks, custom filters, Pierce linkage, etc.  It's easy to get carried away, haha.
