Guest Subrina 7 Posted July 26, 2003 Share Posted July 26, 2003 My hands are just about up in the air to signal surrender. Weber dies once my primary valve is 1/2 way or so open, unless you quickly bring the secondary into play-- a "flat" spot that kills the motor. Float is adjusted. I installed a Pressure regulator $9 at Action.. Changed fuel filter just in case. Checked vacuum a million times. Switched the carb from having a choke (very functional) mounted at 180* to removing the choke, mounting the way most of you guys have. Swithced around primary main jet from 132 (ford cortina stock) to 140, no change. Double checked transition ports, valve in primary is on the level w/ first one. Accelerator pump works fine. Diaphrams are good/new, jets are clean. Idles like dream, timing is very ballpark. Plumbing is good. Why won't it go??? Tex, you had mentioned something about an annoying flat spot and its remedy. If you read this, please put it down. Should I be trying smaller primary jets? .005 down? Jets provided are appropriate for maybe a 1700cc engine, I would think I would be drivable.. I am beyond needing moral support...just want my car back (weberized). Quote Link to comment Share on other sites More sharing options...
Guest Ratty2Subaru Posted July 27, 2003 Share Posted July 27, 2003 hey, you should drop on in to Austin's Subaru repair shop! (i have 6 subarus in the driveway, 3 of witch are awaiting service lol!!!) anyways, i had issues with my weber, and I also have the weber complete tech book! we can take a look at it, and also, you could come by and get that moustashe bar if you need it still... (even though I might need it for the next offroader :evil: muahahahaha!) you know my number right? ttyl! Quote Link to comment Share on other sites More sharing options...
Guest SubaruTex Posted July 27, 2003 Share Posted July 27, 2003 i went to Bow Wow autoparts when i was getting annoyed with my flat spot. they recommended i change my transition jet, or whatever its called. The guy Chris there, he did it for me. I still have 2 jets from that buying experience. I suggest taking it there and talking to them about it.

Guest Mike W Posted July 27, 2003 Share Posted July 27, 2003 Have you tried removing, disabling, and/or plugging up those extra gizmos? I'm asking myself what about your Weber is different from everyone else's? Maybe those extra features on yours might be causing the bad voodoo? Too many things sucking vacuum presure? Are all the vacuum ports drilled out and flowing properly? While you get your's sorted out, do you want to borrow that junk yard carb I have? It's grungy and needs a rebuild kit put in but should work. Quote Link to comment Share on other sites More sharing options...
Guest cameron Posted July 27, 2003 Share Posted July 27, 2003 Did you block off the vacuum port that operates the choke?? You may need a F9 or even a F30. Is the pump jet working when the throttle is opened? you should see a good clean stream of fuel when the throttle is opened slowly. Quote Link to comment Share on other sites More sharing options...
Guest E Zap Posted July 27, 2003 Share Posted July 27, 2003 Whether you decide to keep trying to work on getting that POS to work or whether you decide to just wait and order a new one, that Brat is yours till you're up and running. Whoever you bought the carb from owes some explaining if they sold it to you under the pretence it would work on your car. I'll stop by again this a.m. EZ Quote Link to comment Share on other sites More sharing options...
Guest Subrina 7 Posted July 28, 2003 Share Posted July 28, 2003 Thanks for the invite Austin, but my car won't make it out of the drive till I get this resolved or put the hicrappy back on. Ya, still want the mustache bar, right now that is backburner material I am afraid. Still gotta get mobile and out to Yakima to see Jerry and or Pat and pick up Baccaruda's drop. Mike W, that is exactly the next step I will take in so far as just replicating the plumbing the way others out here have it all. Thanks for the offer in your carb, it has already been very useful as a reference, and its jets (just to swap in and out and experiment) Cameron, Only Friday out here did I try reversing the carb, without the choke to see if it made a difference (rule out the notion of condensation/puddling of fuel) Did notice the vac port for the choke, blocked it off temporarily. Made no difference in function. Pump seems to be A1- plenty of gas in a nice stream going down the pipe. Tex, thanks. If you happen to have a 160 jet (or other sizes) laying around, let me know. I keep getting out of work 1/2 hr before BowWow closes, and am on bike. It would be tight getting out there. Mr Zap, I don't think there is anything wrong w/the carb as it sits, was wonderfully clean upon investigation (removal of top, components) But I am running out of ideas. Might just take you up on the loan. Quote Link to comment Share on other sites More sharing options...
Guest GlCraigGT Posted July 29, 2003 Share Posted July 29, 2003 is there any chance that you ended up with a feedback version of the weber? i know my parents 80 chevette had one on it so the possibility exists Quote Link to comment Share on other sites More sharing options...
Guest Subrina 7 Posted July 29, 2003 Share Posted July 29, 2003 Of all the #$^%, how about a backward venturi over the primary barrel. Of course, I feel stupid for not figuring it out sooner. It is always something stupid w/me. Hoofbeats=horse, not zebra. The fact that I did not put it together only makes me feel a touch better. I'll get over it. Thanks guys.

Guest E Zap Posted July 29, 2003 Share Posted July 29, 2003 Awesome! Happy for you man, I know what you've just been thru. You did well not to shoot the car. Gimme a call. Quote Link to comment Share on other sites More sharing options...
Guest baccaruda Posted July 29, 2003 Share Posted July 29, 2003 hey caleb! how's it running now? think of how much WORSE you'd feel if you ditched the project or wasted the money to have it looked at somewhere. and at least you didn't have to break anything to learn a lesson! i'll bet even the carburetor experts do that stuff once in a while..

Guest edrach Posted August 1, 2003 Share Posted August 1, 2003 Just a question. I've got a weber on our EA81 Brat which works just fine. I was contemplating adding a fuel pressure regulator until I checked the fuel pressure from the existing fuel pump--3 PSI! Regulator wouldn't do me any good since I'd lose a couple of PSI in the regulation. Besides it seems to be working just fine as is; don't fix what ain't broke. Is there something wrong with the fuel pump or is this normal pressure for an '84 Brat? Quote Link to comment Share on other sites More sharing options...
Guest Mike W Posted August 2, 2003 Share Posted August 2, 2003 Hey Ed, in case you haven't already gotten an answer on this, I've been told by a couple different guys that our pumps drop pressure as they get old. So by that theory this probably is normal pressure for an '84 Brat and maybe your pump might be on it's way out. But then again, look at how many guys are not using a regulator and their cars seem to doing fine and not starving for gas. Who knows, maybe your pump will last forever putting out a nice 3psi! I only put the regulator on mine because the pump was making 5 or 6 psi and the redline dude said 2.5 was what the carb liked. Like ya' said, if it ain't broke, why fix it!
