I'm guessing this would work as a return spring, but I would need 3. https://www.piercemanifolds.com/product_p/lt5000.htm

sorry, 2.4

Thanks guys. they are 40dcoe151’s, Italian made. From what I know it’s a stock cam and engine is stock, I did just install headers 6-1 and a full exhaust from motorsport auto. I believe pipe diameter size is 2.5.

ok guys some good news. I got the carbs back from a rebuilder, got the car to idle at 950-1000. It needs some fine tuning. From what I am understanding there are 2 main adjustments, mixture and idle speed(throttle stop). Also I can't get the synchrometer to read below 5 and some 7. Also what setup are you guys using for the main throttle linkage return spring? I am using the 280z adjustable hook and I bought a metal linkage(don't want to use the original plastic ball rods) from that to the crank, just need one more metal linkage from the gas pedal to the crank. Does someone sell a kit to mount a bracket on the valve cover and a return spring? I was told to go to home depot and get a spring, unsure which one to get. Thanks!

any updates? Thx!

Thanks for much for the info!

anyone have a replacement for part number: 08214-83010, apparently Nissan said this was on back order.

Man these look so good.

lol. ok so ordered the 280z linkage, i’ll try it out next weekend.

lol what just happened?

does anyone make the actual rod that just goes in or the only way is the cut and weld the original? I would like to keep it with just a rod and not put a cable for now.

not that I saw, even tried with out it. 05893DB2-C96E-439B-B12F-7680EBED770B.MOV

I actually have the Pat Braden Weber book, I also have DCOE’s on my Alfa but I haven’t touch those in years. I think i might be missing the balls that go in the accelerator circuit under the weights because there’s no gas in those circuits.

Your website is such a helpful resource, i’ve must of been on the site a few times. The first 2 carbs are not squirting from the accelerator pump jet. I cleaned out the jets and removed the accelerator pump with no success. I also then blew compressed air into the accelerator pump passage and the accelerator jet passage still no success. I can feel air coming from the accelerator pump passage to the accelerator jet circuit but no gas.

Hi Guys, Just installed a rebuilt set of 40DCOE's. I can't seem to get the car running. Is their only 2 adjustments, the throttle linkage adjustment at the base of the car and the idle mixture screw by the rear. I did notice a few plugs have gas on them and there was plenty of gas in each carb. Is their any other adjustment I am missing? Also what is everyone using to block the fuel first fuel line and the coolant lines to the old SU's? Finally who sells the throttle linkage? Thanks!
