Changing Carbs on an 88

[denguy]

What is the model number of the Weber carb that folks swap for the stock carb on a 1988 Festy?

32 36 DGEV worked great for me. Throttle turns the same way and the original cable thing goes right on it. Choke ends up on the back but who cares. I got one for a Suzuki Samarai which is a 1.3 and it ran great after minor adjustments. I guess it comes pre-jetted for a 1.3 litre engine.

Pop that thing open and let us know what size the main jets are! That would be valuable info for us.

Zoe60............could you post a pic of your installation? Thanks

Is there a less expensive Holley version of this one? If so does anyone have the model number of that one? Thanks

Click on the link that shcsc left in the first reply. I put pictures in there. I'm kind of scared to take it apart but I guess it would be helpful. Are the jets marked? If not how would I measure them. I've never looked at a Weber jet before.

I have always used the carb for the '81 to '85 Escort 1.6L. I've never used one on a B3, but they work perfect right out of the box for the B6. You can usually find a new/rebuilt one on eBay for around $75.00.

I wouldn't recommend taking it apart just to look at the jets. If you are not familiar with the carb, you could damage the bowl gasket or bend the float just for starters.

Yeah, I'm a firm believer in "If it ain't broke don't fix it." If you find where drddan put his on I think he listed all the jets that made his run good.

Zoe, all the jets are marked,with size stamped on each jet. There is nothing to worry about with taking the top of the carb apart to access the jets. Nothing will go "flying" out and you wont bend anything. Once you open up the top, you will see this is the simplest design ever and so easy too work on!
This link shows a guy taking the top off of a Weber and it is all pretty straight forward.

The jets to start with are the IDLE jets and the MAIN jets.
Idle jets are on outside of carb. One for PRIMARY, one for SECONDARY.
The idle jets look like little brass screws on side of carb. Simply unscrew these to remove or replace.
The main jets are inside the top of carb, in the float bowl, at a 45 degree angle on the bottom side of the float bowl. Again, simply unscrew these to remove/replace. Experiment with different sizes to arrive at a tune for your engine. Takes like 2 minutes to change jets, unscrew the existing jet, screw in a different one, go for a drive!
Once you get it right, it will have no hesitation, no bogging down, and will pull well from a stop. Any questions, feel free to PM me.
These carbs are made to be "user friendly", especially made for ease of tuning and changing things around.

The idle jets are both 50's on mine. I haven't taken the top off yet but I will when I get time. I guess it would be helpful to everybody 'cause mine runs great. I looked at the Weber site and they say the "original" settings were primary idle jet 60, secondary 50 so mine is different.

[zoe60]

OK I did it. The idle jets are both 50. The mains are both 140. The air corrector jets are: primary-170, secondary-160. The pump jet is 50. I couldn't figure out how to get the emulsion tubes out- sorry. I'd like to know myself. All I can tell you is I am very happy with the way mine runs. it doesn't bog, it Idles smooth, and is way more powerful than it was with the original carb. I do have a performance cam too so your results may vary. Good luck! Looks like the only difference from the Weber web site original settings is the primary idle jet.

[drddan]

What you have in your carb, is VERY close to mine. Sounds like it came "setup" for your Festy. Kewl!
I am very happy with mine too.

Now tell me how easy that was to open up the carb! :

In case anybody wanted to know

My jets:

Idle Jets
primary=.050
secondary=.055

Main Jets
primary=.140
secondary=.145

Air Correction Jets
primary=.165
secondary=.175

Tried a .115 on primary main = bogged down, went back to .140
Gonna try .125/.130 to see how that does. Trying to get best mileage and performance
