jetting configurations depend on your engine build. my configuration may be different than yours. for example, my engine has: Comp Cams 252S Offy Dual Plane Manifold DT Header, Cat, Flowmaster and 2-1/4" pipe everywhere else. those are the basics. I'll have to find my notes or pop the top to run down my current config. the 32/36 did not work well for me as shipped, though, so I've spent a lot of time tuning. still not convinced it's optimal, heheh, but it "feels" pretty good  I'll try to drop by with some numbers later today. need to shoot some carb cleaner in there anyway.

I just have the offy and the carb so far, but I also plan on doing at least a header and 2 1/4 exhaust w/muffler only.

from experience, allow me to offer you the advice of keeping all your stock components, just in case you ever want to go back.
when I first bought my truck, I went crazy bolting all sorts of stuff on trying to wake up my little 22R engine, specifically, I installed a Weber 40/40 and a 4:1 header, ditched my cat, and installed a Magnaflow straight through muffler. those are all high rev type upgrades, and not at all what I needed. I was looking for a low to midrange torque boost, not high end power. my point is, think about what you want your truck to do differently or better, and make sure that what you're doing aids in that goal.
that said, be careful with exhaust mods. I've found that the tri-y header design works well in opening up the exhaust enough to breathe at higher revs (3000-3500+), but more importantly, maintains the scavenging effect that the overlapping runners provides (note that it's the same design of the stock manifold? the engineers did that for a reason) I ended up putting my cat back on. why? because while things flowed nicely and freely at higher speeds, without some back pressure, my little 22R lost a lot of its bottom end, the low to midrange torque, which was exactly where I wanted the boost. it felt empty and lifeless.
you can always take the cat off later if you think it's choking the exhaust. for now, try to resist the urge to make all your upgrades at once, and do only one thing at a time so you can really get a feel for what works.
just a little wisdom from someone who's been down that path before, and wasted a LOT of money on things that didn't work, only to come back to moderate upgrades over the stock design.

Thank you for the experienced viewpoint. I'm not big on getting rid of stuff unless I have to. (semi-pack<img src="/forums/images/graemlins/rodent.gif" alt="" />) I've also experienced horrible performance and also reduced gas mileage due to (I'm guessing) not enough backpressure in the exhaust pipe. So I dont want to go crazy with freeing up the flow of my exhaust and I still want the exhaust to be fairly quiet. I picked up this Ford mustang muffler (aftermarket oem) that I figure would keep me close to what I need on back pressure and keep me pretty quiet. the aftermarket cat that I had replaced the old one with was only $50 for the cat + welded in and is only like 2 years old so should be good, not to mention the flange is 2 1/4 and would fit into the system if I don't like performance without it. I can always cut the pipe to add it later.

the single most important thing I've learned in attaining responsive drivability and good fuel economy with the Weber 32/36 on this engine was making sure the timing is correct. that means making sure you're getting ported vacuum and manifold vacuum to the right ports on your distributor, and making sure that neither of the diaphragms is torn so that the vacuum advance actually works as designed. so, no vacuum leaks, and proper timing. this is where you're going to get your throttle response and ability to hold cruise under light throttle, because the distributor will advance your timing allowing you to run leaner. that means no more foot to the floor all the time, which will give you better fuel economy, and with the proper timing, you'll find you flog the pony less to get the response you want. spending money on anything else will just be a waste unless this stuff's properly set up. trust me. I used to get 12mpg before I figured this out  now I get 17/18 in the city, about 22/23 highway. it could probably be better if I had stock size tires and stock cam. or if I could keep my foot out of it

keeping my foot off of the floor... thats always tough (I think a strategicly placed dent in the floorboard may help me with that too) <img src="/forums/images/graemlins/lol.gif" alt="" /> good idea though I would have never even thought to check the diaphragms in the distributor.

Good to know the weber talk is still going on. I now have my 38DGES on and running. My car does not have an exhaust yet though. It feels like a dog, but I'm sure lack of exhaust pipe has something to do with it. I have the LC Engineering 4-1 long tube header on it. I will resist the urge to try to tune the car until the exhaust is plumbed. This winter will be for body work. Exhaust may wait until spring.
BTW, there should be a way to get that 1 million post weber discussion here from offroad.com shouldn't there?

Hey Ron, good to see you here. yeah, apparently a lot of stuff disappeared from ORC. I collected that post and tidied it up a bit some time ago, along with resized photos and such, and have it available for download on my website. I think it's got most of the good stuff in it. for anything missing, there's a pretty good Weber community here and I'm looking forward to interacting again, as I've just taken a renewed interest in my truck. then I also have a collection of other Weber stuff I've picked up over the years; manual, various install guides, photos, etc. it's a little over 40MB of stuff. I'll keep this up here as long as it doesn't see so much traffic that it kills my allocated bandwidth  I'll see if I can sort through it and maybe we can find a less nested place on the forum at which to share this information, but for now, let's just keep it a "pssst, hey check this out..."

Just have Kewlynx move it to the tech archive. It sees little traffic, but will be there for posterity. Heck, maybe you could break it down to a quoted post (with credit to it's owners) and she can put that in there instead.

I have a pdf of the same stuff you have saved on my computer too  I know what you mean about your truck. I lost interest in my car too. Too long not driving it and household projects piling up. I figured winter is a good time to get some work done after I work down the list some. It will probably be AFTER Christmas. I guess I can accumulate supplies and parts until then.
