Weber 40 DCOE

[paradoxx]

Im looking forward to build the L18 of my new datsun with all of the parts Ive been collecting. I got the Weber but it has missing the linkage, I visited http://www.piercemanifolds.com/linkage.htm but I have so many choices and have no clue about which ones will fit or need for the 510.

 

I will be using a Lynx manifold so if someone can guide me thru or someone has a spare kit or something let me know. Thx!

The linkage you need depends on the your manifold!

 

Do you have this kind? It has a linkage rod, and you can use a cable with it.

 

 

Here's nother look for a different engine, with bellcrank type linkage:

the manifold and carb is just like datsunfish's one.........but I will take a pic for a accurate guide for you guys.

This is my stuff...

Bump!

I found better performance even in the bottom end using dual 40 mikunis compared to a single 40 mm weber. Very cold blooded with the single.I worked with the acc pump volume and nozzles. I think the outer cylinders dont get their dose of accel pump enrichment upon sudden acceleration.

That is a Lynx crossover manifold! Should have better torque than most single-DCOE manifolds.

 

I can see that the throttle linkage is there:

It looks like Datsun throttle cable type. The bracket at left is where the cable ferrule fits, the rounded part below it where the cable end attaches.

 

Like this on a factory datsun 1200:

 

Can you convert the 510 to use a cable instead of the stock 510 bellcrank linkage type?

the picture you've quoted it is a picture of the manifold from Datsunfish......the pictures below those are my actual manifold and carb. The thing is that I have no cleu what do I need exactly to make it work. This mani and carb where originally installed on a 510 but I never looked at it when it was installed.

I don't know what you need for a 510, but the linkage for all kinds is available new from Redline.

First and foremost, get some softmounts/insulators(don't buy the redline ones they are shit) having it "hardmounted, carb right on to the manifold ,will cause you all sorts of problems.

thank you, Ill have that in mind.

I havnt really sized mine up to the 510 linkage but it looks like it would be a bolt up deal. How do folks do the duals on a 510? Even with the cable linkage on my duals I had to modify to use them on my 521. What issues will the lack of insulators cause? Isnt that basically an icing over concern?

[67411sss]

It will most definitely throw off your settings if you have a lot movement with the engine and primarily vibration going from the motor to the manifold to the carb.

I found this one for Z application, the linkage setting fits right up to the bellcrank. I just have to consider 67411sss's comment, but as far I know, the people here that have almost the same settings had nothing to regret about.

Maybe i'm wrong:blink: all of the sidedraft set ups i have had over the years have all had insulators and i would bet so do a lot of other peoples it seems like a pretty common thing unless you have a 190sl with solex carbs then it comes factory hard mounted. Just some advise, do what you will with it:)
