Johnboyee Posted August 20, 2015 Report Share Posted August 20, 2015 first off, I have used the search function!! Didn't help with what I'm having trouble with, does anybody have and good pics of an 82 with a weber installed, the problem I'm having is with the throttle cable connecting it to the carb, I have the mount on the head side of the carb but it won't open throttle to wide open! Just lookin for some good pics of setups or any other useful info! 1 Quote Link to comment
datzenmike Posted August 20, 2015 Report Share Posted August 20, 2015 The Z22 throttle pulls from the passenger or right hand side of the carb doesn't it? 1 Quote Link to comment
Johnboyee Posted August 20, 2015 Author Report Share Posted August 20, 2015 Yes sir, on stock carb it does, but I can't use factory cable holder due to it being to tall and hitting part of the carb body 1 Quote Link to comment
Element103 Posted August 20, 2015 Report Share Posted August 20, 2015 The Redline linkage kit for a 32/36 DGV carb on your year is 99007.116. Take a look at it...I think the angled piece with the slotted hole is a replacement for the stock bracket. 1 Quote Link to comment
Rhino13 Posted August 20, 2015 Report Share Posted August 20, 2015 Take a pair of big pliers, bend the old throttle bracket then where it mounts with the two bolts, move it down so the top hole on the bracket is on the bottom bolt. I'll go out and take a picture soon, it sits up against the carb but works perfect. 1 Quote Link to comment
Johnboyee Posted August 20, 2015 Author Report Share Posted August 20, 2015 Element103, I'll check out the part number when I get home! Rhino13, I thought about that but wasn't sure about only having one but hold it on, pics would be great 1 Quote Link to comment
Charlie69 Posted August 21, 2015 Report Share Posted August 21, 2015 Take the linkage off the stock carb and install it on the Weber. I am guessing you have a DGEV 32/36 or a 38. Do as Rhino said. No need to buy parts. Also connect a light throttle return spring. 2 Quote Link to comment
Johnboyee Posted August 21, 2015 Author Report Share Posted August 21, 2015 I got the factory mount working, needs a little tweaking but it works, I like the return spring idea. I realized after the fact (I cut the lead end off cable) that I could use factory linkage. It's running but won't idle and runs rough, already replaced plugs, dizzy cap, rotor, wires, both coils still have spark, I read either they work or they don't do they should be ok, should i get a new distributor? Or what other electrical problems might I look for? I have the E choke hooked up the the factory blue wire that went to factory carb, is this correct? After running it for a bit the choke seemed quite hot to the touch. 1 Quote Link to comment
Charlie69 Posted August 22, 2015 Report Share Posted August 22, 2015 Quit buying parts and replacing. Post some pictures and some information about the Weber. You most likely have a vacuum leak. Get some starting fluid and lightly spray around the base and any other possible vacuum leak areas. Quote Link to comment
Rhino13 Posted August 23, 2015 Report Share Posted August 23, 2015 I got really busy so I apologize for not posting up a picture, Charlie's setup is nicer than mine haha but here it is Don't mind the electrical tape, I also keep forgetting electrical connectors... 2 Quote Link to comment
Johnboyee Posted August 24, 2015 Author Report Share Posted August 24, 2015 Charlie69, I haven't bought any parts I didn't need, I swapped motors in this truck since original was locked up! Rhino13, that's exactly the way I was thinking you meant, and I'm running mine the same way for now, one day I'll make a new bracket myself that holds the cable with less angle of attack on it, but now I'm having idle issues, it won't idle, I checked for vacuum leaks around base and any other possibilities, but haven't found any, I've even adjusted the idle screw in both directions in and out about 3-4 turns with very little effect, right now I have sdjusted slight tension on throttle cable to keep it running at idle, time to do more research ! 1 Quote Link to comment
Rhino13 Posted August 24, 2015 Report Share Posted August 24, 2015 You have an idle screw and a mixture screw. Do you have your vacuum advance from your distributor hooked into the Weber? You can pretty much delete all other vacuum lines to make chances of leaks less and to take out unnecessary things. Is the carb brand new? Make sure you get all the bolts tightened down enough to not have a vacuum leak through the base. If the carb isn't new it could be a variety of things. 1 Quote Link to comment
Charlie69 Posted August 24, 2015 Report Share Posted August 24, 2015 It has hard to tell what a problem is or was when when parts are replaced in large quantities. It is much better to replace one part at a time to find the problem . Where is the choke wire coming from? Quote Link to comment
Johnboyee Posted August 24, 2015 Author Report Share Posted August 24, 2015 Ok... New carb 32/36 DGEV, vacuum delete has been done, yes vacuum advance is connected to dizzy, everything else except vacuum to brake booster is capped off, checked base adapter plates by spraying carb cleaner with no change in rpm. According to paper work I was adjusting slow idle screw and not mixture screw. Choke is connected to stock blue choke wire 1 Quote Link to comment

Middle man Posted August 24, 2015 Report Share Posted August 24, 2015 Because I had electric choke issues with my new weber [that the guys solved] I check my choke with a cheap 12v light. One to ground other to choke connection.Also none of my adjustments worked because I had a huge vaccum leak.I'am curious about your booster brake vaccum connection.I have limited experience,but those vaccum leaks now have my complete attention... 1 Quote Link to comment
Johnboyee Posted August 24, 2015 Author Report Share Posted August 24, 2015 Middle man, yea my brake booster vacuum line is the last suspect on vac lines, but I also have one to transmission since it's an automatic, the brakes where redone before I purchased the truck, but it is original booster too, plus it's has cruise control which adds extra crap, might end up removing that. 1 Quote Link to comment

None_zero Posted March 2, 2023 Report Share Posted March 2, 2023 I wonder... it seems like pretty much everybody who owns one of these trucks puts a weber carburetor on it. What's the benefit? How is the webber superior or different from the oem carb? 1 Quote Link to comment
datzenmike Posted March 2, 2023 Report Share Posted March 2, 2023 Small increase in performance as it's a larger carburetor. You do loose some advantages of the Hitachi though. Usually the Hitachi needs rebuilding or cleaning or problems with understanding and trouble shooting it so easier to just go Weber. 2 Quote Link to comment
None_zero Posted March 2, 2023 Report Share Posted March 2, 2023 So speaking of carbs You can't really see it in The photo but when I went to check for carbon build up I noticed that the throttle valve is open just slightly while the truck is off. Is this normal? Quote Link to comment
Stoffregen Motorsports Posted March 3, 2023 Report Share Posted March 3, 2023 It has to be open a little bit to allow airflow. Too much and it will be pulling fuel through the main jets, instead of the idle jets. This can make it run on or diesel when you turn off the ignition. Quote Link to comment
Thomas Perkins Posted March 3, 2023 Report Share Posted March 3, 2023 (edited) Why are you using a manual choke,Get one with a Electric choke.Also use a Idle cut off solenoid.Here is a site to get one..Best running 720 as you see in the picture.Got to spend money to get it right.Also replace the accererator cable,got me a pioneer one..https://www.ebay.com/itm/392584468616?chn=ps&_trkparms=ispr%3D1&amdata=enc%3A1S1eCMN2wQMmELx51neNYRw3&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&mkscid=101&itemid=392584468616&targetid=1644837434843&device=c&mktype=&googleloc=9011420&poi=&campaignid=16743749222&mkgroupid=138744546207&rlsatarget=pla-1644837434843&abcId=9300842&merchantid=131363253&gclid=Cj0KCQiA0oagBhDHARIsAI-Bbgfv-qrEw0YWYjCwLGfdFmALucc80HJqWXClmwEIPrESM-RJc5p39ZQaAoSlEALw_wcB Here is a new pioneer cable.I got mine from their.https://www.autozone.com/fuel-delivery/accelerator-cable?filterByKeyWord=pioneer+cable&fromString=search&isIgnoreVehicle=false&model=pioneer Edited March 3, 2023 by Thomas Perkins Quote Link to comment

What's the benefit? How is the webber superior or different from the oem carb? The weber DGEV 32/36 is a simple carb compared to the stock Hitachi. I bought my 86 720 Z4 5 speed in 2010. Talked the guy down from $2500 to $900 because the truck ran terrible he was sure it had a bad engine. Drove it 75 miles to my temp home and ordered a new Weber from Pierce Manifolds for it, installed the Weber and I am still driving it today as a daily driver. I drove it home from Battle Mountain Nevada to Tolleson AZ towing a tandem axle Uhaul trailer full of Datsu/Nissan truck parts Edited March 10, 2023 by Charlie69 3 Quote Link to comment
