40? 44?

Weber IDF

Dorello (sp)

Others?

I've had Solex, Weber 44s, etc. on my cars in the past, and by far the best is the fuel injection. The carbs were used since the injection was not very tunable for racing. For a street car, you can't beat the injection. If yours isn't working, I have a complete 73 1.7 you can have for parts.

what you like is what i consider "best"i run weber IDFs.im gonna start playing with some solex p40s.i only recomend if the motor has been altered to the point you need carbs. (adjustability)

what cam? what displacement....

stock motors rock on stock FI....

hot motors suck with stock FI

hot motors with big cams can run great on carbs and or PEFI

all in the application.....

my experience has been that Dellortos are much better runners than webbers. mm for mm they even flow more. Dellorto jets are very expensive now and hard to find. Empi just started making NEW webber IDF knock-off, made in china. teh china carbs use teh readily available webber jets, venturis and all other parts are interchangeable
webber jets are cheaper and very easy to source

I've run them all, Solex's are cool, but not easy to get right on a T4, and the manifolds are hard to come by, parts are hard to get too for regular people.
Weber's are great, but a all around they run a little rough compared to Dellortos.
I tried them all and found Dellortos to be the best all around- but its just my experience. My 1.8L with 36mm Dell's drove like it was fuel injected all year round- rain, snow, sun- perfect.
But dont swap to carbs for no good reason, try and work with the FI first, go to carbs if it gets real bad or you have no FI.

p.s. I have a whole Dellorto fer sale setup just sittin here- what a coincedence.

just ask any FI questions here on teh club. we will help you fix it

FI is better that carbs

AAron hit the nail on the head...

stock engines should stay stock FI...

hotter cam? carbs or aftermarket FI
bigger than 2.0 or mild 2056? ditto

the bigger engine also will change which carbs... 2056 is fine with 40s, 2270, 44s, more? 48s

also depends on who is tweaking them, and playing with the jets to make the carbs run perfect! carb guru can do amazing things with the jets and get them very smooth... a fool such as I? not a chance
