My friend rebuilt the carb. He did JUST that for years for a living. So I ASSUME he knows what he is doing. That's how we found the wide open flat track plug in above post. I knew it was going to be hard to explain. I was just hoping somebody had that same problem in the past. There is no binding, have double springs... I did notice at one time fuel was trickling in on the left side at an idle. Then I revved it up and that went away. And didn't come back. All I can say is standing next to the car and reaching in and pulling the throttle back JUST A TOUCH... It goes up, but then begins to climb up on it's own. And I am talking 2 or 3 THOUSAND RPM's. Not just a little. Then I pull it back and it takes 5 seconds to go back to an idle. I also noticed that when it comes back, each time I have to adjust the idle screw. Cause it wants to die, OR it is up to high. Never goes back to the nice 900 idle. There is no longer white smoke coming from the exhaust, and the exhaust does not burn when standing in back of car close and bent down.That was fuel dumping in from that plug being installed. Probably didn't have to change the fuel pump, but that's ok, better to start out fresh. Got an all original rebuilt with the embossed AC logo. Advance plate not sticking cause I checked it and it runs back and forth freely. I retightened the carb down delicately with a 1/4 inch drive mini ratchet holding it in the palm of my hand. Making sure not to over tighten. It should be fine and plenty tight enough.

 I think I may have to just get another carb for now. Cause I WANNA drive it. Then send mine out at a later date. There is a Holley 4053, 3923289 brand new in the box online for $640 with free shipping. Is this ok to run and get me down the road for the summer? Not showing the car. Thanx everyone for the help so far.. Here it is... Danny

bcmiller here is a shot of the carb numbers. And thank you for checking with Jerry on the pitman arm. I have found it several more places since my post, so I am hoping it is fine, and all those one's for sale are correct with there info.... Danny

Well I headed down to Steve's Camaros today. He warranted the caliper and threw in a set of pads. Yes he is a great guy. He is closed on the weekends, but I called his cell and he opened up for me. Scored some nice original '68 parts. Like an original water pump bypass hose, rigid pump to carb fuel line, and some other misc. goodies. I get to walk all over the place upstairs and down and look for stuff. Found original Corvette trim rings in the box. Original diamond mesh air cleaners in the GM boxes, on and on, just a treasure trove of goodies. Went next door to see his cars. He has an all original Hugger '69 Z/28 that he bought back in the 80's. And a nice original black car '68 Z/28 with Cowl Plenum. Also bought in the 80's for just a few thousand!  Cool Cool  Then he took me to lunch down the street. Good times, nice visit.

 On a bummer note, I went back and installed the Caliper and bled it off. Threw the wheel back on and lowered it down. Installed the new fuel pump I got from Heartbeat city. And fired it up to go for a drive and the carb is messed up. Just a touch of throttle and it just keeps climbing up all by itself like it is being giv'in more throttle. But I just was holding it at like an 1/8th of an inch of throttle from outside. Then it takes a long time for it to come back down. You know, instead of racking it and having it come right back down, it goes up... then takes a long time to come back to idle. What the hell is that? I remember it happening to me in high school, but don't remember what it was. I just wanna go for a real ride, instead of the super scary 2 mile ride home the day I got the car off the truck. Couple close-ups of the bypass hose. Nice and close. Oh, and sounded a little arrogant with my last post about taking pictures. I was just quoting Ansel Adams  Smiley... Danny

Jim, yes, that's what I was saying, some old trick for full throttle. I assume it was re-jetted during the rebuild. The guy that built it that's all he did for years is these flat track carbs. Probably over 100 of them. So he MUST know about the jetting. I have only started it for a minute to check for leaks. Front caliper is leaking internally... dang it. I was going to take it for a real drive today. Instead I gotta drive down to San Bruno to Steves Camaro and see if he can warranty this one out... Angry Angry

Well I was trying to get the carb tuned and just could not make it happen. So I gave it to a friend for a rebuild. Here is what he found. Apparently this is some kind of flat track power valve mod. You can buy them from Holley, but this one is hand modified and machined. Nice ... If all you want to do is hold the throttle to the floor around a circle track  Angry    P. S. more of those close up pictures ya 'all like. Remember it's not the camera, it's who's behind it that counts.

Hey Kurt, thank you SO much for checking in... Just wanna make sure things are good. I thought I had the pitman arm pictures in here somewhere but maybe not. Here is what I have in my picture file.
 
 What makes you think the carb is original? Is this the norm being dated 4 months away from most everything else on the car? You got many other documented '68 original cars with this early carb dating?

JohnZ sorry to bother ya all the time. But follow-up, so I pull the belt, great, NOW...can I ALSO then pull the vacuum line, or should I leave THAT connected? Will I have a vacuum leak if I leave it? ... Danny
264  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: July 31, 2014, 12:59:36 AM
JohnZ,
 Can I pull the belt and run it without? I here guys talk about deveining. I guess that means to pull the guts out of the pump. I would rather not do that. What can I do or not do? Thanx... Danny
265  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: July 30, 2014, 01:36:28 AM
I read somewhere that you HAVE to have something in the top of the smog pump, or it will keep pumping into the manifolds and this is NOT good. Some kind of valve? True? What goes in this hole? Can I buy one? Can I run the engine without the belt attached to the pump? ... Danny
266  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: July 30, 2014, 01:29:03 AM

Yes Jimmy, this is just soap stone. And then I lightly blow and take my finger and get rid of the excess. Then I edit the picture extensively of course to get that dark surface look. That really makes the numbers stand out.
 OK, I am done for now, no more pictures... Danny
268  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: July 23, 2014, 11:08:05 PM
Thanx, I appreciate that. There is just no way I can do it all by hand. Maybe, but it would take all thru winter.. Sad Sad   And of course I am excited and want it done.
 
   Here below is a picture of the front pad with letters and numbers filled with soap stone to better show if these are original correct GM font and style stampings... Danny

Gary, Thanx... I just know this was a big investment for my girl. And I wanna make sure it is all ok. I spent a lot of time getting info before the purchase, but I am no expert, that's for sure.

  Speaking of preserving... Here is a couple more paint work shots. LOT'S of elbow grease. And it is a fine line, you gotta pay attention while scrubbing. Going to use soaked paper towels with evaporust so I don't have to scrub THE WHOLE CAR! Just don't have the strength. Here is the top of the left fender complete and waxed with eagle one..... Danny
