Weber IDF. 40mm would work. 44 IDF with 32mm Venturi, appropriate jetting. DO NOT buy a "new" weber package! You would be better off buying the cleanest, used set of Italian or Spanish ones you can source and either rebuild them yourself or hire a pro to do the job. Dellortos are a good option also.

Among others, but yes. I'm uncomfortable pointing out one specific ad and appearing biased. That being said I think I'll list a set of dels I have and see if a limited buyer base and plenty of inventory helps drive prices down.

Back on point. The set of carbs, outside rebuild, and a cable throttle setup will be less expensive than carbs that chances are won't work.

RPM plays a factor as well as how large the motor is...

Doing a quick search, I found 34mm carbs supposed to flow in the 109cfm (each) from one site...no idea how accurate.

If you play with the calculators you can see the relationship of engine size and rpm...increase either one and you need more air going thru the carbs.

I'm not so sure those carbs would be the appropriate choise for the engine combinations you describe.

Limited by vent size really,ran these carbs on various t1 motors and they go fine but they were smaller motors,I would think the 40/44mm kadron/solex. could be made to work ....but that's not what you have (IMG:style_emoticons/default/sad.gif) (IMG:style_emoticons/default/sad.gif)

Frankly those carbs suck....lots of experience here.
If you brought them to my shop, insisting that I put those on you car, I'd pass on the job and wish you good luck.

Dual weber IDF, aftermarket EFI or stock FI, all others are a waste of time and money.

Or Ljet. Components are far cheaper and readily available. Drastically increasing the displacement and retaining what may be the FI cam isn't going help tuning issues either

1.7 Liters
That's the biggest the OP should go with his 2.0 running those carbs.

In my 2.0L I am running dual Dellorto DRLA 40mm and 32 vents with great success. One of the great advantages of running carbs is that eliminates so much clutter from the engine compartment, making it so much easier to work on other things.

Apparently he doesn't want to spring for different carbs.

Traditionally, one would not build an engine to suit a specific set of carbs... especially ICTs. They aren't worth much and really only belong on Beetles or a MPG-oriented engine like a 1.7.

I would think if you were going through the trouble of rebuilding an engine, you'd start with your desired displacement/purpose first, then source a set of appropriate carbs for your needs. Otherwise you're leaving a lot of performance on the table.

Not trying to sound, harsh, just presenting you with the "typical" way things are approached.

...or a 2275 that spins to 3150 rpm (speculative made up number)
