Can anyone tell me what the difference is between a 32/36 and 25/26 webber? Are the numbers just the primary and secondary bore sizes? I'm looking for an upgrade for s friends sierra and so far have come across both of these and the g16 carby's. Just wondering what are peoples thoughts?

[Rusho]

A weber isn't an upgrade for a Sierra. They are average at best on hills, power increase and fuel consumption is suppose to be better, but cannot comment on that too much as I have never been in a zook with one. I have however seen one struggle on hills from fuel starvation. The vitara 1.6 carb is suppose to be the better option

Fast answers, I like it

So when you guys mention angles is it side or front/back angles that are the issue, or all?? Mine is efi so I've never experienced it.

Does anyone know if the vit carbs can be jetted right?

In summary I'm hearing power upgrade = webber, stalling fix = vit??

[royce]

There are a few threads on here about modding a stock sierra carb for more power, these are worthwile mods and shit over webers and vit carbies, both of which suck in stock form

why spend heaps on changind something when you can make what you have better for a few dollars

do you have pics of the 25/26? never heard of one that size before

there are also other codes on there like DGV, AGM, IDE etc that are the model of carb

There has been some talk on here recently about using 3K or 4K corolla carbies. I gave a good rundown on this to one of the guys that frequent the site, he has done it and the word has slowly leaked out. It is a simple cheap changeover and the results are very good. Do a search for comments and I have sent you a PM with further details.

The 32/36 is the size of the throats. The other numbers (which I think are 26/27) are the size of the chokes in the throats. Never heard of a 25/26 weber. The 32/36 works quite well on both 1.3 and 1.6 engines, so don't let some fool go telling you they are too big.

I used to run one for quite a few years on my old rig, nice simple carb which never gave me any issues. Very noticeable performance increase without sacrificing the highway or cruise fuel economy compared to std. Never had any issues with up hill fuel starvation but on steep downhill descents they will tend to flood. For the overall gains the carb gave I found it quite acceptable. Many people haven't got a clue about tuning the carb hence it will run like shit and thus it will be deemed a shit carb.

I very much doubt a general Mechanic will be able to tune the carby well... the Mechanic at Suzistore, had to do a training course to know how to tune the Zook carby... they have to be tuned, Hot and Cold, plus a few other things, but after he retuned my old 89 Vit carby, it ran perfect !

I would get a recon/rebuilt 1.6 Vit Carby, and get someone who knows Zook carbys to tune it !

And this is the big issue these days. A person who actually knows how a carb actually works will have no problem with any carb placed in there hands and a carby schematic. People trained to do a specific carb go through virtually a check list to determine the fault and cannot stray from what is written in the book. If its not written down its not fixable in some minds

and if you it this way you will have spent just as much as going EFI. Webers work well and can be tuned yourself but it takes time to get it right and you need to modify the float bowl vent. plus they really hate restrictive intakes.

The corolla carby is much easier and just as good as all the alternatives and are so simple to fit.

Do a search on here for a few posts about them and have a go.

I'm guessing this guy has a 32/36 and is reading the choke sizes?????

[royce]

looks like its off a shitter escort

[Built4thrashing]

That not a ford webber. It looks like one that sometimes were used on Pugs or volvo's or even alfa's.

Just put a 4K carb on my Sierra. So far, results have been good with an increase in low end torque/drivability and a bit more top end. Holds 100km/h much easier and what was a 3rd gear hill on my way home, is now a 4th gear hill. Bit early yet to see what the fuel economy is doing.

Easy conversion and well worth the $100 it cost (s/h carb, carby kit, choke cable and a few studs)

I would not recommend the weber if you like climbing steep hills or climbing rock ledges. It will starve of fuel at even small rock ledges on a short wheal base car. They do not like angles. This has been a cause of embarresment for me in the lada on several occasions. Its also really hairy doing rock ledges in reverse, another thing I would not recommend

To clear things up too, my weber was properly tuned to the engine by professionals, so no amature stuff ups causing the problem

So why didnt the experts recommend or install your carb the otherway around so it wouldnt stall up steep hills? The flood out on steep descents was livable with the low range tcase gears in my zuk. Never had uphill stallage/fuel issues.

I would rather have someone who knows what they are doing, do it once and its fixed... than someone who thinks they know what they are doing, and keeps trying different things, and ends up making it worse...

HERE is a page that details the differences in models of the 32/36 Weber (and Holley 180). Left hand/right hand versions, electric/thermo choke and different venturi sizes are described and donor vehicle sources for 2nd hand models.

I know we don't do it on this forum, but it's bugging me. The name is spelt WEBER, with just one B in it. I thought I should add that as it will help in your web searches if you get the name right.

i totally agree i had a webber no troubles at all way better than standard people just need to take the time to get a good tune

[SuziBlu]

99% of my driving with the weber is 100% fine, far better response than stock aisin, far better low mid and top end power. I love them.

I do get pissed off with it when I get hung up an have to try and get down backwards coz of a stall. An in running sand, that is very frigging tricky.

Im thinking of a 38 38 as they say they have solved the stalling issues.

Lol and how have they done this? Its fundamentally the same as the 32/36. The only real way they could fully solve the up/down hill stalling problem is if teh fuel bowl was on teh side of the carb, not front or rear.

Dan

[SuziBlu]

Yea, im waiting for a reply from the seller, its a EMPI not a weber, this is the imitation job. Same as the 180 holley.

Dunno how, but thats what they are saying in the sales pitch.

[Cozook]

Is there some way of putting xtra fuel in for climbs or pressurising the carb or something that can forever fix this problem with webers...

I'm dumb so this is where you come in.................

Scavenge pumps and pick ups set into the bowl but thats no simple task. Like i Said before teh fundamental flaw in these carbs is the positioning of the fuel bowl and the effects of gravity.
