Carb Questions, yes - I searched first... Options

Building a 2056 and almost complete with it except for carb rebuilding and a few other details. Going with dual Dell 40's.

My gasket kit came with what I will call "spacers" that are used between cylinder head and FI runners. Do I (should I) use these when mounting my carb manifolds? I did not use them on a bus engine I built years and years ago and it ran well - for a very long time so I am tempted to go without them, but thought I would ask.

If there is significant good reason to use them, where do I find the seemingly very (very) thin gaskets that go on each side of them (head side & manifold side)? I ordered intake manifolds from Pelican but them seem a bit thick (I can use them if I choose not to use the "spacers").

Also have a few questions about accelerator cable and carb base plates. Can I re-use the cable that is in the car (it was injected and ran well)? If yes, is there an "off the shelf" bracket to mount it on the engine such that it operates the cross bar linkage? And finally (for now) does the cross bar linkage go on the front or back of the carbs (depending on base plate orientation)?

Pics of your carb'ed set-up might really help me out here so if you got 'em, please feel free to use 'em.

Calling all Dell/Carb gurus. The rebuild guide and the schematic in the Dellorto Superperformance book call for a washer, an O-Ring and a spring for the mixture needle(s). On all 4 carbs that I currently have, there is no washer in front of the mixture needle. There is an O-Ring, then the spring, then the needle.

Anyone know how bad it is that I don't have the washer? My rebuild kits have the O-Ring, but not a washer.

Also, I have it on good word that I should run 34 Venturis for this build. The vents in the Dell Doctor kit measure 38. So I am not gonna install the kit. I do kind of like the idea of the re-located air inlet for the idle jets with the kit, so am curious about using that part of the kit, just not the rest? Do we have thoughts or feelings on that?

As always, any/all input appreciated.

OK, I've got a .pdf copy of the 6-7 pages of instructions that came with my CB Dell kit, along with my notes from my early- to mid-1980s installation. I also have both of the 6+ page articles from "Dunebuggies and Hot VWs" (May and June 1983), and another from "VW Trends." All provide pretty good rules of thumb on set-up, jet sizing, etc. Is there a way to post these here? Even if not, I'm willing to email them to anyone that wants them--PM me if that's the case.

FWIW, my DRLA40s are set up with 30mm main venturis, 55 idle jets, 135 main jets, 180 air correction jets, and 9164.2 emulsion tubes. I know these are a little smaller than the factory settings, but they seem to work well with the current engine rebuild (balanced "GA" 2.0L, Elgin 7008-4 cam [280* duration, .332 lobe lift], Mahle Euro PC set [8.0:1]). Not sure of the HP numbers, etc., but this set-up let me max out the 120 mph speedometer at the end of the long straight at Seattle International Raceway. (IMG:style_emoticons/default/smile.gif)

Hope this helps.

Elliot and CuddyK, thanks pictures of the cable holder and the input on the Tangerine cable set-up!
