I have a 1.8 carb engine that I want to hear run soon, maybe over the holi-daze.
What would you use ?
The 34 ICTS seem to be a tidy set up that would allow some much needed room under the hood.
But.....I hear they are a pain the ass to tune - I feel froggy.
The Weber really has a bad name but there sure are a bunch of them out there and ease of tuning, parts, etc.
Wadda think? (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)

Does either one pass the "float test"?

Yeah. Thats the one. Certainly is a question of two evils. Best of luck. I'm sticking with original FI for a while yet, then I'll look at at other FI options.

I've been pulling the injection systems and installing carbs (notice the s). The lesser of your 2 evils is twins.

Yup--anything at all is better than the single-carb setup. Unless you go to a lot of trouble to heat up the manifolds. Then maybe--maybe--it can work OK.

So the twins it is.
I really want this as a back up plan for FI but I am lacking a few pcs.
I have no idea if the FI ECM is good and the injectors look like hell.
So the big problem with single carbs is the " heating of the manifold" ?
Maybe like the old type 1 engines that frosted the intake with ice? (IMG:http://www.914world.com/bbs2/html/emoticons/chatsmiley.gif)

Anything is better than the piece of shit progressive.... The ICT isn't a bad carb at all, the only thing that sucks about them is having to remove the top of the carb to make a jet change...

I've seen what the FOUR guys can do with carbs.

Steve N., Nathan, Albert, Sir Andy...

If I was running a FOUR again, Webers would be on board.

I ran 34ICTs on a type III for years. Easy to tune, ran great, warmed up quickly. I have the progressive on my 914. Absolutely horrible. RUN AWAY! RUN AWAY!
Anything would be better than the single progressive on a flat 4.

Sure, but just look what can be done with modern FI.
I've driven a car with two dual Webers, and it was nowhere as good as the original FI. I'm not saying it cannot be done because it certainly has been. However it takes a much greater skill, and lots of parts, to do so correctly.

Well I guess we could make up a progressive dual set up !
Twice as much to complain about. (IMG:http://www.914world.com/bbs2/html/emoticons/sawzall-smiley.gif)

I agree with the suggestion to go with the ICT's, but having "dual" progressives actually solves most of the problems they are known for on 914's. I've got electric chokes, and for the most part you wouldn't have any idea you were running carbs. The only issues I've had were going to higher elevation in Moab for the Red Rock Classic. I've got my idle rpm set pretty low in vegas, but up there, the fat mixture had me down to 400 rpms or so. When I got back down here, the idle jumped back up, and I haven't touched it since. I'm guessing very few kits were made to put dual progressives in a 914.

I'm voting for the dual ICTs. Not optimum, but better than the progressive.

I've only seen/drove one car that ran decent with the single progressive carb set up. It had small intake runners though, which would help with the world famous low end gasp the single is known for, and the guy did a lot of tinkering with the jetting to get it optimized. Or at least as optimized as you can get with a set up that's ill suited for the application.

If you don't mind having the engine totally fall on it's face when you punch it from idle; or if you don't mind the engine never really running well in cool weather; then the single is for you (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) They could be considered fool proof though. If it isn't a piece of corroded crap, the car will run, not the best but it will run.

Don't be intimidated by syncronizing dual carbs. It's not black magic.

The problem lots of guys run into with carbs is having the wrong carbs (usually too big) or the wrong venturi and jet package for the displacement and cam (again usually too big). If you have the wrong size carbs and/or the wrong venturi and jet package, you may as well have a single progressive.

The european 1.8's had dual Solex carbs(IIRC), which are similar to the ICTs. I'd like to see the air cleaner set up for those first hand.
