  • Good to see it up and running! Did you take it out to Woodward tonight? I"m over on the other side of the state, so was not able to hit Woodward.

    I've always heard good things about Fairchild...this experience just adds to that.

    • Yup - I went and got gas earlier in the day, and ended up deciding to take it to Woodward, since I might not have another opportunity to do so this year. I just screwed the armrest directly into the door - it's supremely uncomfortable to drive the car without one - my elbow just hangs in space while using the wheel - no thanks.

      So, long story short...car really didn't run great on the way there, and especially on the way back. I mean, no incidents where it wanted to stall or anything, just hit the gas and it just sputters and has very little power before suddenly clearing up and then it's fine. It did it more often than not...but there were those "not" times where it was fine. I have no clue, but it's obnoxious.

      I think I need to check fuel pressure - maybe I'm dealing with a shitty fuel pump? Maybe it's because I'm probably low on oil (it's hard to tell what my actual oil level is with that stupid aftermarket dipstick/tube, but there's like...1mm of oil on it)? Who knows.

      With the calibration, it should be a set it and forget it...not **** with it every time you drive the car.

        Very true. I'd check the filter along with the pump if you think low fuel might be the culprit. Have you had the tank out of that car? I can't remember....

        • Filter is only in the carb inlet, and was replaced when I rebuilt the carb last September, but the fuel pump remains a constant. I wish there was an easy way to test it, like with a schrader valve on a fuel rail (I have a fuel pressure tester, but it's basically only for fuel injection), but not really. I don't want to replace something that isn't broken, especially right now, but at least it's literally right there on the passenger side of the block - with a huge path cleared because there is no smog pump or air injection valves in the way.

          Tank has never been out of the car, but it is full now, so that would be...fun...given how large (capacity) it is. I did think about that while filling up.

          • Burn that gas up this Friday on Woodward!

            I would still check that filter in the carb. It will give you some idea how mush trash might be lurking inside the tank.

            If you do the pump, don't forget about the pushrod.

            • It wouldn't be the worst idea to check. Getting the fuel line out is just a bit of a *****. It's not hard to get to...but it's hard to get a wrench on it without it rounding off.

              At that point I might as well try and see how much it's pumping out. Maybe I can figure out some way to get some fuel line or something on it to measure pressure.

              • Just got the new left hand seal from Fairchild, and now I have the matching set! That only took two months, in total. RockAuto absolutely sucked, while Fairchild was a hero!



                Makes for an easier comparison to just how gigantic what is on the car right now is compared to the Fairchild (left), which looks to mimic the factory seal much better. The rear "knob" of the seal is very evident of this - the Fairchild is "carved out" while the other seal is all filled in, and all the rubber on it is way too stiff.





                I'll probably wait until next week when it's a little warmer to swap the seals (especially because my Cobalt will be at the dealer - and thus, out of the garage, giving me a lot more room to work on the Camaro).

                • Excellent! I'm glad they came through for you.

                  Yes, I remember that nut on the Q-jet. Not fun.

                  Not a relative, and less than scientific, but the difference is dramatic.

                  • Yup! They rock! Can't wait to get em in the car...and my wife can't wait for those door panels to be out of the house.

                    As far as the fuel pump, I don't want to pull it off...but a few cranks should tell me what I need to know!

                    Sounds like I probably need body mounts too...explains the giant tire rub I have on the rear of the left tire on left turns...the alignment holes are off by about 1/4"...

                    • Installed the new Fairchild door seals last Wednesday, but only got a couple good pics of what was on the car (off the car) compared to the new ones. Pretty obvious the old ones are a lot thicker in areas they shouldn't be, but the pictures don't show just how stiff the old seals - two years old now - still are, in addition to being too large.




                      I went and installed the door panels today (as well as the vapor barrier on the driver side door, which has been sitting inside for almost as long as the door panels have, as I Gorilla-taped it back together, haha), and my god, what a difference. The felts touch the windows, and they sit entirely correct now. Only took six months!







                      This is actually the first time the left door panel has had the door handle surround since owning the car, nice not to see the metal inner door panel anymore. But it's nice to finally have the door panels reinstalled.

                      • Those look great. New seals, felt...all makes a big difference.

                        • Absolutely.

                          And not having the vapor barrier taking up the dining room table and the door panels on top of the dog's crate...makes someone else happy.

                          You still gotta slam the doors - but I had to do that even after I removed the seal entirely, so...something else is causing that, but I feel like after sitting closed for the weekend, I didn't have to slam it as hard, compared to the old seals, and it's only been less than a week.

                          • So, finally got around to checking on the fuel pump since I had my brother to give me assistance (I didn't want to spray my wife with gasoline - my brother, I didn't care so much about doing that to ).

                            The service manual says to "let engine idle for 30 seconds"...after it tells you to remove the fuel line from the carb and position it into a suitable container...not sure if the engine will idle for 30 seconds (or more) off just the fuel in the bowl, but...okay. So I cut the time down to 15 seconds and pulled the coil power wire. The measurement was at least a pint in 30 seconds, so I figured a quart in 15 seconds would work. Definitely had at least a quart, so, fuel pump looks to be all good.

                            Next up: checking the plugs. May have just fouled the hell outta 'em when it was running pig rich.

                            • I pulled plug number 3 (one of the easiest to get to - has the dent in the header tube for access) to start with today and found it to be in good shape. Then I decided I really had no interest in pulling seven more plugs.

                              My thinking is that if the carb running rich for a while caused any fouled plug issues, it should technically be present on all plugs.

                              • I got sucked into doing some Photoshopping on the car over this weekend - initially, just to see how black projector headlights would look - if they'd fit the overall "theme", I'm going for. Then I put on wheels.

                                I'm a bit rusty, but seems like I still got it. It's by no means perfect...at all...but for 50 minutes (and not having a Wacom tablet screen like I did years back when I really did my best work), I'm more than happy.



                                .
                                So, it's settled in my mind that the C7 Z06 wheel is really what I'd love to run on this thing...the difficult part is how to fit them. The Z06 wheels have about two inches more backspacing, since modern cars have the hubs pushed much further out than older cars. So either I'd have to run a pretty large bolt-on spacer (while they're perfectly safe, since they're bolted to the lug studs, and then have their own studs, I generally do not like the look, given the brake is so much further inboard - and I'd imagine they would look extremely odd with drums, though ultimately it'll eventually have discs out back), or figure out how to push the wheel mounting surface out about two inches. The rear is easy - run a wider rear end...but the front...hmm.
