TeamCF Posted January 3, 2012 Share Posted January 3, 2012 (edited) So I just got back from emissions testing my 83 GL with a Weber 32/36 on it. Hydrocarbon limit is 220ppm here in Oregon. I got 22ppm. CO limit is 1%. I got 0.0124% CO+CO2% is supposed to be over 6%. I got 12.4% No fancy tricks or fuel additives, just tuned it. The inspector's jaw about hit the floor. Didn't even have to do a second idle test. All emissions equipment removed except the catalytic converter. Even the EGR is gone, because I could not get it to run right with it hooked up. (though the idle test would not be affected by that anyway) For reference these are the jets I'm running to keep the adjustment screws in the Weber factory spec. I live at about 1,200' and have adjusted it to run good here at the house. But the test sites are just over sea level. Primary Air corrector--- 170 Secondary Air Corrector- 160 Primary Main Jet--- 140 Secondary Main Jet- 140 Primary Emulsion Tube--- F50 Secondary Emulsion Tube- F50 Primary Idle Jet--- 55 Secondary Idle Jet- 50 Right now I'm. Edited January 4, 2012 by TeamCF I seemed to have had the wrong secondary idle jet written down. Quote Link to comment Share on other sites More sharing options...
Flowmastered87GL Posted January 3, 2012 Share Posted January 3, 2012 Ha nice, I never had to take any of my webers through DEQ, but good to know that they could have passed with some tinkering. Though I highly doubt I will ever own one again :-\ Quote Link to comment Share on other sites More sharing options...
TeamCF Posted January 3, 2012 Author Share Posted January 3, 2012 I'm loving the Weber. My Hitachi did well right up until the end (throttle shaft leakage, wouldn't idle no matter what) But the Weber is a joy to work on and tune. Quote Link to comment Share on other sites More sharing options...
edrach Posted January 4, 2012 Share Posted January 4, 2012 (edited) I absolutely agree! Weber carb is just great and with proper tuning will have no problem passing any emissions test other than California (emissions are well within spec there, but CA insists on OEM parts and the weber was never OEM on any Subaru I know of). Aside from being emissions friendly, a properly tuned weber is just great on gas mileage and driveability. I've had two Brats and a GL wagon weberized. Never regretted any of them. As an aside, in an earlier life, my rally car was a '71 Datsun 510 with the two liter engine and weber. Greatest combination ever for TSD rally (except for my 2002 BMW which preceeded the 510; I couldn't afford to keep the BMW in spite of the fact it was a dream to drive). Message to OP: you should put the jetting info into the USRM. Really useful information which seems to be hard to come by.

I live in Portland and was thinking of trying to bypass DEQ altogether, but now I just may try to pass it. I am running everything the same on my BRAT. Cool!

TeamCF Posted January 4, 2012 Author Share Posted January 4, 2012 Yes, really. hehe I'd say get it running good and give it a shot. Your Brat might want slightly different jetting to pass, but it is possible. And jets are only like $5 each over at Discount Imports. So a little fiddling around is worth it to get it just perfect, they also have a guy there that knows Webers, only gotten to talk to him once but he pointed me in the right direction. (for the most part only the idle jets ever need swapping, lots of generic Weber info on the web.) Like this: http://www.poustusa.com/weber_carb_pages/weber_carb_page.htm And this: http://www.carburetion.com/weber/adjust.htm For a totally different animal, but this has good info on the basics of what does what and how things affect each other (read the "Weber D**V tuning as a systems engineer" part) : http://datsun1200.com/modules/mediawiki/index.php?title=Weber_DGV_Tuning And lots more. They all end up pretty much repeating the same thing though. Then you just apply it to your car how it needs it. Quote Link to comment Share on other sites More sharing options...
BratWarrior Posted January 6, 2012 Share Posted January 6, 2012 I'm pretty sure I have the same jetting. I may have a 60 secondary idle. Good to know you passed so easily! Quote Link to comment Share on other sites More sharing options...
TeamCF Posted January 6, 2012 Author Share Posted January 6, 2012 Yeah my secondary is actually a 50. I had it written down wrong. (Well I had it written down right, but had it saved on the computer in a text file for reference wrong, And I just copied that and didn't double check my paper.....) I figured I'd get it to pass, just didn't know if I'd need to keep trying or not. I did seafoam the crap out of it a couple tanks beforehand though. Doubt any was left in the system. But I'm sure that helped. So that detail might be important. Quote Link to comment Share on other sites More sharing options...
