weber instructions?

[89AccordHatch]

anyone know where i can get detailed instructions on installing weber 40 dcoe's?

Ask Phyedux... hope I spelt that right.
and do a search for 40 DCOE or Dual sidedraft. There should be a how to.

thanx!

Try this link. It has info on DCOE carbs, linkages, installation, and tuning.

Hey 79EK1... I wanna see your car.

Mine's an old first gen with the engine apart getting ready for a rebuild, not much to look at right now. I'll have to dig up some pics and figure out how to post them. I'm getting ready to replace the 38DGES with a dual 40 DCOE setup I recently got. Hopefully, It'll be together before Christmas.

Gotta tell me how that motor runs with the dcoe's I was surprised how much the dgv did for that tired old motor. No fair, you can just buy a manifold for an ek1. I could have bought a manifold for the es2 mine use to have as well if I had kept it.

Andy, It took me almost a year to find the manifold. It still needs some work, as I've got to port match it, and drill and tap the runners for the brake booster and vacuum advance lines. I might go with a balance tube setup, so I'll have to get the tubing and fittings and lay them out. With the special order pistons, parts and block work I want done, it's going to be a while.

While you're doing all that are you going to do away with the cvcc? or are you lucky enough to have a motor that isnt equiped with it.

I thought that cvcc just meant that you had two intake valves per cylinder that opened at slightly different times to exhance air-fuel mixing. If not that, what is cvcc then?

[79EK1]

I swapped the CVCC head for a non-CVCC Canadian head a long time ago. It is a standard two valve head, with a better shape to the combustion chambers and i/e ports. I had it milled, ported, and installed larger valves. The CR is 10.2:1 with a 0.50mm overbore.

Mike, the CVCC engine used a smaller auxillary intake valve and chamber to fire a rich a/f mixture into the main combustion chamber and ignite a relatively leaner mixture there. There were three valves, two intake ports and one siamesed exhaust port per piston. So you're correct about how CVCC works. All that stuff in the head made performance mods hard.

It also didn't work that well.
