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?

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.

and get someone who knows Zook carbys to tune it !

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 !

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.

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

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

can anyone add to this discussion?

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.

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.

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.................
