Weber 32/36 thread

[zoe60]

Just throwing this out there. Maybe the guys with Weber carbs could compare notes and figure out how to get our cars to run their best. Mine has an '89 B6 with a 32/36 and it does real well. One thing I will say is that float level is very important. Mine was cold natured and had inconsistent idle until I corrected it. We could discuss everything from jets to adjustments.

mine came preset up for the festiva,runs great but really runs it's best in warmer months like any carb i've ever had

[blueoval]

long time since i've seen you on here,talked to you when i first got my festiva

[zoe60]

Yeah, it's been a while. I mostly lurk on here these days. I still play with my Festy a lot though. I got real lucky last week and found a nearly perfect passenger seat that matches mine in the JY. I took the cushions and the covers off of it, washed the covers, and installed it all on my driver seat frame! If you look close you can tell it's a passenger seat but it looks like brand new. Renewed my interest in the car! How is your car doing? I swear Webers add about 10 HP don't they?

[zoe60]

No one interested? Has anyone noticed that since we actually have these things mounted sideways, that they will cut out a little when you take a turn real fast? Mine does it going left. (choke on back) I'll bet with the choke on the front they will do it turning right. Doubt if anything can be done about it.

I've got a new Weber in the box and am going to be using it on a B6 swap shortly, so I hope this thread catches fire.

[zoe60]

Lots of talk about Festy adapter plates these days. Maybe they will be available soon. Will make installation a hundred times easier! Good luck.

yeah going from stock feedback to the webber is at least 10hp difference and makes anything under the hood easier,as far as my car goes it runs like a sewing machine,i'd jump in it and drive to cali without even thinking would it make it.always been a ford guy never paid these cars any mind now i'd never be without one

You sound like me! I got an '02 WRX, it's in great shape after me working on it, and I still like the kick I get out of my Festy. You expect the Subie to kick butt, but my little Festiva will really surprise you! It's like an upset in sports. Way more entertaining than what's expected.

I suspect that this is largely an artifact of increase in amount of ethanol in gasoline these days (up to 10% now from 5% during the past 10-15 years). Up until the demise of carburetted engines (late 80s) no one added alcohol to fuel except as a cold weather gas line antifreeze.
Try running a tank of Premium (whatever it is make sure it has no ethanol in it) through the engine and see if that makes a difference. Higher octane fuel makes no difference (solely inhibits premature detonation (ie pinging)) to our little engines but ethanol blends sure do mess up air/fuel mixtures.
Great thread! I intend to follow this out even though all 3 of my Festys are EFI. I love non-electronic-feedback carbs for their simplicity and reliability.

yeah i've been trying to remember to fill up at the stations i know that have 100% pure gasoline, and the festiva is so light that just a few more hp goes so far as far as take off and everyday driving mines still stock b3 and will be until engine is wore out then i think i'll move up to a b6,i drive my car for work and that's 500to 600 miles a week so i love the b3

I have an '89 with an '89 B6, a Weber 32/36, and the original intake manifold. (Hoping for the Matt Dickmeyer model to become available) I was getting 34 MPG and thought it should do better. My main idle jet was a 50, but I had to turn the mixture screw out more than 2,5 turns so I went to a 55. Secondary is a 50. Mixture screw was then at 1.75 turns and she ran better. MPG stayed the same. My primary and secondary mains were both 135's so I changed the primary to 130, and the secondary to 145. After a tank of gas I now get 39.1 MPG. My question is, should I be happy with that or try a 125 primary? Don't want it going too lean and nuking my engine. Timing is at 14 btdc. The car runs perfect. I know there is no way to do it properly without at least a wide band, but I don't have one. Open to suggestions.

[Movin]

If your original o2 is in the manifold and still working wire a cheap HF voltmeter to it and watch the voltage while driving the car. The original sensors should be able to report a range from near zero to .900 something. If yours can still report this after it is warmed up you can use this data to insure you have no lean spots. Power readings will be above its area of accuracy but if you bounce off of lean then go up one that would be about the best you can do lacking lots of experience and equipment.

39 with a four speed is getting pretty close!

[zoe60]

Thanks Movin, that's a good idea using the o2. Would it be too lean if the voltage stayed at .9, or stayed around zero? I do have a 5 speed. I do feel pretty good about 39. It's the best it's done since I had a B3 with the original carb. Don't want to get too greedy.

[zoe60]

Never mind Movin, I looked it up. I guess if I stay closer to .9 volts it may not be too lean. I think I need a wideband if I am gonna try to push it that close.
