Ok-So I lied. I hated my old zenith carb and I hated my new zenith carb and I hate me for being stupid enough to think that a new one would work. I am curious what others have experienced? | ||

LOL!!!!  Before I actually had a Series, I wanted one with a Weber 2-barrel instead, because of all of the problems I heard about Zenith and Solex. My Series already had a 1-barrel Weber on it (the 134ICH), which is a decent carb. A lot of folks have a lot of trouble out of the 2-barrel Webers, because they just plop it on... you really need a different cam and have to rejet it, otherwise the 2-barrel is just throwing too much fuel down in there. Also, the linkage has to be reworked so that it's not acting like a 2 stage, but both together. But, if done right, it can run well. For the time being, I'll stick w/ my single-barrel Weber.... A lot of folks like different Rochesters, but then other folks don't. On different vehicles, I had one that I liked, but on another I didn't. SU, Holley, there are other carbs out there, too. If you're not trying to keep a car-show restoration, but instead are wanting a driver, try others, and see what you like, or don't like. But, since you have a new Zenith, you may want to hunt down the annealing / glass-plate instructions and get that one functioning for you. Out of curiosity.... what problem was it that you're having? Are you sure that it was the carb at fault in the first place? If something else was amiss, and you swapped carbs, you would expect to have the same trouble still..... just an afterthought..... -L | ||

When I first bought the truck it had an old zenith on it. It was running rich so someone told me to get the zenith rebuild kit so I did that. After rebuilding it it ran rich, real rich so i found out about the warping problem and the o ring fix so i did both those and it still ran crappy. I ended up buying another zenith carb(mistake), it was one of those decisions that I don't know why I made. Maybe I wanted to keep it as close to original as possible I don't know. But it worked fine because I really never went too far with it all the while still running rich. Lately with MAR coming I decided that I needed to adress the rich running issue and got no where with leaning it out so that is when I decided I better get a new carb. A weber single barrel that I hope to put on this weekend. I could have missed something and it isn't too late to get the zenith running leaner but I am not sure what. What put me over the edge with the zenith was when i learned that 30 years later they still produce a carb that warps and then the hole that needs to be plugged is there...still. art at RN said that their position is that that hole is plugged by the gasket which makes sense but what about the warping. It just made me madder than hell and they sell it for about 100 bucks more than a weber single barrel. Lets hope that the single barrel works better. If you think I missed something tell me, I'll try anything. | ||

Thomas, I'll go ahead and tell you that out of the box, the weber will make your truck run rich. I HIGHLY suggest that you also buy extra jets. From my own experience, my weber came with a 175 for its main jet. This made it run ungodly rich, so after some tinkering I found out that a 155 works makes the truck run with the right mixture. I thought I would go ahead and inform you of this so you knew what was going to happen. FWIW, go to www.britishpacific.com and look under FAQ and then go to the carb section. That will help you in your quest for knowledge. As for the weber 1 barrel, it is an excellent carb. It won't fail you and you won't have any problems with it while off roading. Max T. | ||

Hey Max! Hey Leslie! Glad to hear good things about the single-barrel Weber. The truck I've just bought -- haven't yet taken possesion of -- has the 34ICH, which David at TRG put on and has been pleased with. So I'm sure I'll be pleased too. Only thing is, I can't find a manual for that sucker anywhere. The Haynes Weber manual I thumbed through didn't address it, unless the ICH went by another name. I'd like to be able to pull it apart and rebuild it myself, when that day comes, but I'll need a book to hold my hand along the way. You guys have any suggestions on where I might find one? Or Leslie, have you seen an alternative anywhere around? Matt | ||

Well my carb didn't come today so I am going out to try putting an inline fuel pressure adjuster and see what happens as well as a new K&N air filter. Lets hope it is just that there is too much fuel being dumped in the carb. | ||

Matt: CHeck here, I think the 34ICH is listed: http://www.piercemanifolds.com/weberexplode.htm | ||

You guys know what the diameter of the IIa 1971 fuel line is? | ||

I had very good luck with the Rochester single barrel. Noticed quite a bit more power than the Zenith I had on originally, and equal milage. Had it on for 50K miles and didn't touch it once. You have to get the right model. B.P. has them | ||

Someone did a flow test of all the different carbs you can use on a Series. Rochester came in second behind the 2-barrel weber. The test is on the web somewhere. | ||

I just got done placing a pressure reg on the fuel line and the bastard ran rich still even on the lowest setting. Well-i guess the weber goes on tommorow evening. Getting close to MAR-needs to be right. | ||
| Thomas Dahbura (U352) Member Username: U352 Post Number: 194 Registered: 10-2002 |
Weber is on and running really nice except for a wierd hesitation that occurs eradically-could be the plugs are all messed up from running so rich all this time. Maybe some old timers at MAR can help me dial the beast in. Definalty more power though. | ||

Tom, If you still have your pressure reg in-line...make sure you are dialed into about 3 psi. | ||
| Thomas Dahbura (U352) Member Username: U352 Post Number: 195 Registered: 10-2002 |
Hey Todd-I kept the Reg in line and played around with the correct setting and eventually ended up at 2psi. Anything else it seemed like it was acting up. I am wondering if my plugs are fouled becuase of the shitty running on the zenith. It is skipping/missing when it is running down the road but the idle is SWEEEEEEEEEEEEEEEEEET! |
