I have been having so many issues tuning my triple OER/SK dcoe 40 carbs. I recently bought these carbs secondhand. I have been running into issues with idle speed, and synchronizing. The car runs very rough and the engine shakes quite a bit. Problem #1 I attempted to synchronize all three of the carbs but ran into many issues. The carb (#2) in the middle seems to be drawing in a lot of air compared to the carb (#1) and carb (#3). This is with all the carbs set to the same idle speed screw distances. I suspect that carb #2 has a bent throttle shaft or butterfly, but the butterfly opens smoothly with no obstructions. I also checked for vacuum leaks and there doesn't seem to be any. Problem #2 When I put the synchronize tool onto any of the carbs the idle drops and the carb drools fuel everywhere, like a toddler drooling. I am not sure if that is normal or not. Every carb seems to do that when I hold the tool up to the throat. Also when I hold up the sync tool to carb#2 the engine almost dies out. Desperately, trying to find a solution I have to increase the idle speed of #1 and #3 in order to match the flow of #2. This resulted in a super high idle speed of about 2000rpm. Problem #3 Carb #2 seems to also be running much leaner than the others. I had to turn the idle mixture screws a few more turns than #1 and #3. please any advice is welcome.

I am on the search for a complete set of use-able / rebuild-able triple DCOE carburetors. Either 45mm Weber's or 44mm Mikunis is what I'm looking for. I would need everything to install into a 280z with an L28. Can work on trades as well, please see my for sale posting. -
Has anyone ever used the EMPI HPMX carburetors on a Datsun before? I tried to do some searching and couldn't find much of anything? http://vwcatalog.empius.com/vwcatalog/2014/60.html https://www.youtube.com/user/EMPIHPMX/feed They are mostly used on VW air cooled engines, but I don't see why you couldn't just bolt them right up. They have a few videos showing dyno results where they made a few more HP than there Weber equivalents.

Anyone ever seen something like this? Its off a 48/45 DCOE Weber on a race build 3.1L setup. Was this an OEM part or something custom fabricated after the fact? Any known history?

Doing a slow restore on a 72 240 i picked up. Weber 45s were having some trouble sneezing and leaking so took them off to clean em up and replace gaskets, set floats etc. Noticed these adjustment screws which i find no mention of in Haynes manual, or any online reference ive found. These are the later 152s with nitrophyl/spansil floats so im thinking it was a modification on later models? has a white plastic hat/cover. one on each throat. with plastic cover removed needle screw with fastener nut needle pokes through main venturu/choke into carb throat (upper right)

Hello, recently i just recently purchased a used set of weber 40 dcoe. But basically i am missing a few parts such as the three eye joints that screw on to the manifold, and one butterfly and throttle shaft. What had happened was i bought the set of webers that had the three pieces of linkage missing so i new i was going to need those. But me being an idiot i was disassembling the first carb without penetrating fluid so i stripped the heads of the screws that hold the butterfly and the throttle shaft in place and i had to drill out the holes. But the throttle shaft needed to be replaced anyways since one of the ends threads were stripped. So basically i need one throttle shaft, one butterfly, and three of the eye joints that screw in to the manifold. The carbs seem to be fairly old italian weber Dcoe 18 No. 9E ,with a cannon manifold. Any help will be greatly appreciated.
