:thumbup: :thumbup: :thumbup: I finally got the idle problem solved. Remember my settings, ditch them. I am now 1+1/2 turn on the idle speed and 2 turn on the mixture. What I did was to follow what the manual said and some google. The low speed circuit calibration said that my idle jet was too rich, that means that I just needed a hair of air. I found out that the secondary plate on the weber I have does have a screw to calibrate the opening of the plate at idle. http://www.jeepforum.com/forum/f8/weber-32-36-cant-set-lean-best-idle-new-idle-jet-1383024/ What I did was to actually screw in just less than 1/4 of a turn (more like 1/8 to 3/8) and that was it, That idle up to 700 rpm, and I could use the idle speed screw to go up and down as I need, in my case, close to 800 rpm (the manual calls for 950 but I rather go to 800 as the general rule). Also :w00t: I could set up my air con vacuum actuator to open more the carb still being "BELOW" :w00t: :w00t: the enrichment holes, that means no more vacuum advance signal at idle with the a/c on, also no more off idle stumble btw :thumbup:. The accelerator pump now does work, oddly :confused: and I see how squirts every time I push the gas. Now I just have to give a test drive, right now I am just chillin indoors because I felt light headed, I will be back with more info later. Oh, my weber doesn´t have enrichment on the secondary, so it won´t draw gas from there, also I tested and no dieseling so far :thumbup: . Amazing how a little hidden screw (in my case I had ease access to it) can do changes so much :console:

I actually disconnected and had my vacuum gauge connected to see what was happening,and indeed, with my current sets, I see that I have a problem with the jet size of the idle. Come to think of it, the Tercel kit is for the 1.5L, but my Suk is 1.6L, maybe that's the whole trouble, I am just too lean for the displacement and a bigger jet (which is odd since the guides says smaller) but I see the problem is around that

Thanks for the pointer, got the valves adjusted in the afternoon, and now runs better but with this settings: Idle Speed:800rpm Speed screw: 2 turns Mixture: 2 turns After reading again, decided to use the basic settings just to test Speed screw (after touching the lever right?):1+1/2 turns Mixture: 1+1/4 turns and I got that my idle rpms barely got above 200rpms, but with my current settings now I see vacuum on the advance port, so, from what I see, I need a smaller idle jet to close more the idle speed screw and a bigger jet primary jet to compensate the off idle stumble, right? P.S.: about the accelerator pump, if I don't see a squirt the first time but the next time I do, that should mean that there is something going on in that circuit right?

Hi, I am new to the forum, got here because of a carburetor swap I did on my car (wife´s car but I drive and she´s too lazy to drive so I am her driver anyways :P ) Of all the place, I had two choices, the MG club or the Datsun club, and I choose to come here. Mainly because the Datsun is a Japanese car (as far as Wikipedia tells me). I haven´t seen any of those in my country, but there is Nissan and Mazda, being Nissan like a son of Datsun (if I understood the story of Datsun correctly). And secondly, because you guys seem to know more about the weber adjustment than most folks on the web on other forums, I feel more at ease seeing more info and stuff here than any other place. I bought my 32/36 from ebay, from the Redline e-store. And I have videos of how I installed it. Using the Toyota Tercel Kit, that (strangely) fits bolt-on to the manifold of my Suki. (If any video is in spanish, skip to the next one, there are several takes on each one) The thing is, I suffer from 3 things (make fun ye, I don´t speak or write english too well, I even searched the register question in google to look up the answer, being the answer inside the question... damm). #1 The first thing is the off-idle stumble, I believed it was a timing issue, fixed a leak on the vacuum advance (I have ported and manifold vacuum, both of them broken), after that apparently that minimized a lot, it didn´t dissapeared but it minimized a lot. On the installation video you can see that if I blip the gas there an stumble, but waiting like 2 secons and blipping again there is no stumble. #2 The second thing is pinging under 15000rpm, I believe it could be related to the gas quality (usin ron 91, as the manufacturer sticker says), but I could be also the timing, because (6 degrees initial timing btw) if I lock up the vacuum advance (by locking I mean not blocking the ported port, more like putting the adjustment screw on the vacuum canister all the way until it doesn´t move under acceleration), there is no ping or so little it doesn´t notice until you really try to hear it. But the car runs great and pulls hard good (if I gently push the gas to avoid problem #1) #3 The third problem is when turning to the right, the off idle stumble is quite noticeable. But it doesn´t happen turning left, so far what I readed it maybe related to the level of the float so I believe I can address that. My settings so far are: Mixture screw: 1 + 1/2 turns exactly, or maybe 1 + 1/2 + 1/8 turns (being the 1/8 more like a little nugde). Idle Screw: close to 1 turn, more like 7/8 or a turn, but the throttle plate are quite close, and there is no noticeable ported vacuum, even disconnecting the ported line and hooking it to a vacuum gauge shows little (needle varely moving from zero) vacuum. My engine is totally stock, just rebuilt about 4 years ago to 0.30 pistons and bore, and the compression test shows 195 to 200 psi on all pistons (dry test - warm engine, not hot, just warm to almost cold). And pulls up to 21inHg of vacuum (something odd becase I haven´t seen anything above 17 to 18inHg on google). So, no vacuum leaks, excellent vacuum, what am I missing? My finger and sight are tired of searching and no one locally really knows about webers, and I rather fix it myself than taking ti to someone else. Is like an old saying: "Would you lend you wife to someone to play with? Neither I would lend my car to some strange mechanic. Any ideas gladly appreciated. Also, keywords, since I am quite limited on the words I know to use to search function correctly. My bad :(
