Used Weber Carburetor Guide
Here is my guide to buying used Weber Carburetors. I have published this on various websites.
Used Carburetor Guide Here is my guide again for people looking for Used Weber Carbs at the JY or on Ebay Ok, for all you guys that hunt JY's. If you are going to look for a Weber Carb, this is what you should look for. First I will mark the cars and trucks, and then the model of carbs. I will be pleased to tell you if the carb is worthwhile if you find something else. I have the repair kits available. These vehicles had Webers as conversions only. No car in the US or Canada came factory with the DGV or DGAV Vehicles BMW - 2002 with 2 barrel manifolds (best place to find a used Weber) Datsun/Nissan - carbureted trucks and cars pre 1986 L, Z, A, E series engines Jeep-CJ, Wrangler with 258 motor Mazda - B2600, B2200 trucks. Most cars had people that didn’t care about performance other than rotaries Mitsubishi/Dodge D50 - carbureted pickups, Raiders, Colt front drives Opel - Opel GT Suzuki – 1300 Samurai Toyota - Corolla pre 87, Tercel pre 91, Celica-pre 81, Land Cruiser 80's and earlier, Pickups pre-88 Volvo-non fuel injection cars (144, 122) Ford - Old Cortina mark 1 (1967?) Carbs to use 32/36 DGV (manual choke), 32/36 DGAV (auto choke), 32 DGAV, 32 DGV 38 DGAS Maximum performance, mileage will be lower 36 DCD, 28/36 DCD Questionable carbs Holley 5200/Weber 32/36 DFAV - linkage reversed to DGV series, most Holleys have linkage that is not bolted on and some have non changeable idle jets, throttle shafts wear easy Fiat Webers, DMSA series harder to get parts, linkage reversed, 1800 carbs, 34 ADF Renault Webers DIR series- same as Fiat Empi 32/36 Carb - It's pure trash If you are handy, and have access to parts, the Renault and Fiat carbs will work OK Last edited by tekenaar; 01-31-2008 at 03:06 PM.. |

Which one?
"Carbs to use
32/36 DGV (manual choke), 32/36 DGAV (auto choke), 32 DGAV, 32 DGV 38 DGAS Maximum performance, mileage will be lower 36 DCD, 28/36 DCD" I just purchased a 73 Opel GT. I'm trying to get it fixed up. Which carb should I purchase? I know I need to get one - I'm just not sure which one to get. I know the difference between manual and auto choke - but I don't know what all of the other numbers mean. What are the differences? Thanks |

Guide?
To approach this subject more comprehensively, it should be emphasized that just because a carb will fit an Opel doesn't mean you should buy or use it.
The "Holley-Weber" not only will require a custom-modified "backwards" linkage, but will also run lean and overheat the interior of an Opel cylinder head -- so this model shouldn't be included with useable Opel applications. Additionally, whether a used Weber is rebuildable or not, depends on its wear. For example, if the throttle shaft bushing is worn out, that will have to be replaced -- which is a part not included in a standard rebuild kit. Idle mixture screws, idle jet passages, choke mechanisms, power pumps, and other hardware, also can suffer damage after years of use (and are not in the standard kits). Different model types are better for certain applications (water choke for cold-weather driving, 38DGAS for a high-compression performance-built motor, the solenoid-equipped 33B1 where emissions regulations require it). And much of the results of a Weber also depend on the quality of its installation (particularly sealing it from vacuum leaks). So, do the research and get educated, before acting on a suggestion. |

IMHO, the order of preference:
1) Solex: only if you are lucky enough to have one that isn't worn out, or are capable of magic where most of us are mere mortals 2) Weber DF Series (DFM, DFAV, etc) or Holley Weber: Dave speaks the truth about the reversed linkage and is justified in his caution about the reversed primary possibly causing a lean condition. That said, the linkage can be quite readily modified by rotating the last link to rotate the opposite direction, fabricating a quite simple off-set pin at the carb bracket, and the mixture can be modified somewhat by jetting. And this is NOT hearsay, as I ran a Weber 32DFM for about four years and over 50,000 mile very nicely, with no ill effects, and it ran a HELL of a lot better than with the Solex 3) Weber 32/36 DG Series (DGV, DGAV, DGEV): The carb of choice, but it STILL requires proper jetting, or it is a waste of time 4) Weber 38DGAS (or 38DPS100, which is the manual choke version): Great carb, can be used with ANY 1.9 IF properly jetted, but better suited for a higher output engine 5) Weber (or Dell'Orto or Solex or Mikuni) Side-draft, Single first then Dual: Many have found the SSD (Single Side Draft) to be the BEST carb, once jetted correctly, but if you want the ultimate in power and boasting ability, the DSD (Dual Side Draft) is the way to go 6) Fuel Injection: Ultimately, carbs are seldom as good as a properly designed and installed electronic fuel injection system, but that is the topic of a different Forum HTH |

Another thing if you have not considered it is to replace the points with an electronic unit. Cost about 40 some bucks and so easy to swap out I was impressed, takes about 20minutes and another 15 or so to time the ignition after the change out..

So, please tell us why (what's wrong and current engine specs and carb you have now) and what you want to accomplish (goal of all changes) . . . uh, don't fix things that aint broke! |

That's right Otto, I've always had a Solex carb on my Opels and never had any problems, the only problems i have with a carb is the Weber on my wife's Volvo
, can't get the @#*%$#@ thing adjusted so it will idle steady , why can't you adjust the idle on the Weber, like with the Solex?? I find the Webers A BIG PITA .I'm going to see if I can change the Weber for a Solex, the base is the same, I made a new heat isolator and put in some longer headless bolts to fasten the Solex to the Volvo intake manifold, haven't done any work on it for a while because of other chores around the house.

(Volvo = Opel?)
Examples of why Solexes have problems on Opels in the US, include the hotter climate (causes warping of base plates and internal air metering passages), fuel blends (they not only vary by octane and region, but in some areas also by season), and factory guide specifications (which among other things, state on page #6E-50 (of the 1973 factory manual) that you should use #J-23951 "water manometer" tool for adjustment). Because so many Opel owners have experienced problems with Solexes (including "fuel dumping"), I feel it's irresponsible (especially to casual or "newbie" readers) to not recommend that they install a Weber carburetor (which is tunable, by a simple, 2-screw, idle speed and mixture adjustment process). I'm not alone in this opinion, as back in the 1980's the State of California itself declared the Solex carb a "gross polluter" on Opels, and recommended a replacement Weber installation as a remedy.

Hey Dennis Texas I woulds love to have a copy of your haynes manual.... I am still working on an issue of the throttle shafts of the weber..... just trying to see if it is feasible to place new throttle shaft bushings in the body or just replace the carb.... I have already tried the bearings that bigjim sells ..... but still have the dreaded throttle shaft vacuum leaks on 3 different carbs.........

The secret is to not let it dump gas. A proper set up Solex will get a lot better gas milage than the Weber. It has a smaller primary Venturi. Therefore will deliver better around town gas milage. Granted Solex is a difficult carb to set up. But does work real well. It takes a great deal of patience to rebuild and blueprint a Solex. They do work.

. . . easy to see why Solex has much better gas mileage, also easy to see that Weber flows considerably more air/fuel, ideal stoichiometric ratio being the same for both! |
