Is it possible to adapt a sync link to my frd’s?

[rodjr]

The Webers we are talking about are Alfa Remeo carbs, they are not just standard Italian webers, they are a different animal.
There are people here who know far more about them than i ever will, maybe they will chime in at some point.
All i know is (with some outside help on the set up) my Weber 36 idf 44/45, off of an Alfa Remeo....friggin rock!

And they work great with the sinc link.

My Italian carbs came with complete and working chokes too and if you are lucky enough to get that bonus and live in a cool climate keep them. They work really well!

So I went with the Dellorto DRLA 40’s
Been reading ALOT and came up with the following for a 1776, 110 cam,
32 vents
55-57 idle
130 main
180 air

THEN I start reading about peeps running the DRLA 36’s and I’m “starting” to second guess myself.
Were the 40’s the better choice?
I had read the 40’s had a few advancements over the 36’s and decided on the 40’s from alpa1750.

Your engine will like the 40's. My 1776 also has an Engle 110, and 40 IDFs. It is a remarkable difference in power and idling from the FRD carbs I previously had.

Yeahhhhh!
What jets did you run?
Do you remember?

[67rustavenger]

DRLA and IDF carb sizes are not the same.
36 DRLA = 40 IDF.
40 DRLA = 44 IDF.
45 DRLA = 48 IDF.

The Dellorto jets are sized differently than IDF jets too. I don't have the chart available. I measure my jets before installation to make sure what I'm tuning with.

The one very good difference between Dellorto and IDF carbs is.
The Dellorto jets are accessible from the top of the carb. The IDF's have the idle jets on the side of the carb.
To change IDF idle jets. You have to remove the carb to access the jets. Unless you have installed "Weber Windows" in your engine compartment. Or drilled a hole in the inner fender well like Glenn did on his car.

Dellorto carbs IMO, are a far better engineered carb. Compared to the IDF carbs. I like all of the o-rings on the mixture screws and pump jets.

For your 1776. You may be a bit over carbed. But it can be worked out.
Someone will chime in on getting the carbs right for your engine.
I'm not that guy. I have soooo... many dual carb sets. That I can choose whatever carb I desire for the engine I'm installing the carbs on. Then tune from there.

Good Luck.

Some idf's (including the ones on my car) have the idle jets in the top.

[67rustavenger]

So are those 36 IDF?
Then yes. They may indeed have the idle jets on top. I have never seen a set of 36 IDF's. But of all the IDF carbs I listed above(that I own). None have the idle jet through the top.

[rodjr]

Yes, 36 idf's in the pic. There are also 40's configured the same way.

40DRLA should be a fine choice.
There are two different sizes of transfer ports. The holes are different sizes. Take off a cover and check the top two holes. I'd go with

32 vents with 1.8mm BIg transfer ports
Or 30 vents if they are 1.4mm, smaller transfer ports

Wish I would’ve known about your super secret carbs sooner...
I just dropped $700 on these.😡

There are a few members that I really look up to and modok is one of them. The guy knows his shit.
When I see his avatar I always wanna read what he has to say.

Well I'll be damned. Never seen those idle jet holders before. Thanks for posting this solution.

That being said.
I still think Dellorto DRLA carbs are better engineered and have more finite tune capabilities than any IDF carb.
