I rebuilt carbs trying to fix tbis problem @gundee.

Im on it! Thanks.

Thats great info @Zed Head these carbs dont have vacuum ports.

@Patcon all springs were replaced with the strongest one available

@Zed Head I rebuilt all carbs. Plates shafts bearing and seals. They all open and close smooth as silk when engine off. Confused. Thats why I was leaner towards a new manifold

Watch both videos @Zed Head focus on middle carb actuating arm. Watch how it sticks open and closed when shut engine down.

Hahaha only 25! I've tired many different springs and placement if them. Even up to 3 spring and still doesn't absolutely fix this issue or the pedal is too tough to modulate. Thanks for you help. The problem is beyond springs. I ordered new linkage as someone else recommended. Hopefully that will do. I will upload thoes video on YouTube and post it here for you. I want you to see what im talking about @Zed Head

@duffman can you share a link of the linkage kit you mentioned for 80? I found this https://www.piercemanifolds.com/product_p/pm3701-l.htm

No offense taken at all @Zed Head. I'm sure you watched the video, I guess I'm stuck and worried that linkage won't fix it the issue. All linkage was disconnected and plates dont shut when engine running. I have never seen that before! I work on Porsche for almost 20 years and I have diagnosed sticky linkage before. That's confusing me. I'll definitely try upgrading linkage first. I really appreciate you guys and you time

@duffman you have a good point! Now should I try the beefer rod for 150 and hope that takes care of the issue or spend 500 on kenmeri manifold?!!

Hey @duffman I tried removing the center post last year and it did not help at all. Good luck. I just order a external spring linkage though pierce manifold (Search DCOE external spring on google) hopefully that solves it. If not I'm buying a new manifold. I 'll let you know.

@Zed Head I have a cable set up, so pulling up on pedal does nothing for me . I'll check again for air leaks. Thank you for your time

Need some Help... The issue I'm having is idle hanging up around 1500. It will lower to normal (900 rpm) if I blip throttle. Getting tired of doing that in traffic. Middle carb is hanging , but only when engine is running. Carbs open and fully shut very smooth when engine off. Vacuum holding plates open?. Maybe it has to do with the balance tube on the cannon manifold. all carbs have been rebuilt. I swapped carb position and problem stays in middle carb. I heard the cannon manifold suck. Does anyone have some helpful info for me? TIA. 20190815_164848.mp4 20190815_164500.mp4 20190815_180041.mp4

No way! Please keep us posted on that @duffman

@Mike W thanks for that info. I have already switched to cable setup and rebuilt all carbs completely. My issue only happens when its really hot out or I get stuck in traffic. Was your issue was always or got worse under certain conditions?

@duffman here's a link if you have a throttle cable set up https://www.rhdjapan.com/kameari-intake-manifold-kit-l-type-44mm-l6-wire-type.html

Thank you @Zup

I know this is a long shot since this post is from 2015. Mike I'm also having a return to idle problem what triple Weber's in a cannon intake do my shoes only happening when it's really hot outside and the engine temperature engine bay temperature goes way up do you remember if you were having the same issue or was it always?

Looks great!! I love it! Where did you get the seat brackets? Sliders? Hows the seat height? TIA

Thank you! I got in touch with him

Did you get this installed yet? Pics if so. I just ordered a pair from there mck as well.

Those seats are Beautiful! Are they real deal Recaros?

Fixed!! I pushed 2 quarts of brake fluid though the right and a lot of bubbles came from drivers rear. Thanks to everyone for the help and support. I appreciate you guys.

Good thinking. I will look for it tonight

Yes , the rear brakes are adjusted properly. Thanks for all the suggestions everyone.
