Mark, Quadrajet Question

[Longroof79]

Mark,
You're so right about the carb cleaners that are offered today. They don't hold a candle to the stuff of yesteryear. I used to use ...I think it was called Hydroseal...I can't recall, but that stuff would eat the skin off your hands, that's how potent it was. I would dunk small parts, nuts and bolts, etc....and after a good soaking those parts were clean as a whistle.
It came in a 5 gal. drum with the metal basket...even the smell of it was toxic.

I found it. It's a lot pricier than I remember it. http://www.carid.com/gunk/hydro-sea...n-hs5lb.html?gclid=CLTYvrW408YCFQuMaQod6X0KQA

Yeah Jack, those chemicals we used back in the day were pretty potent! It's a miracle we are somewhat normal. Anywhoo the Permatex works really well and doesn't harm aluminum. I even used it to flush out a tired old '70 GTO 400. I poured a gallon in the oil pan, spun the oil pump with a drill and cut-down distributor tool, an I was amazed at the black crud that was coming out. I let it sit overnight and did it again for several days. Then I flushed it with kerosene, and again with cheap clean oil. Man, that motor was like new internally. Ran great for another 10 years in my Malibu wagon. A $20 can of that sure beats a dissassemble/rodding out of oil galleries. I offer that free advice to you and Steve because you both are as cheap, er, I mean frugal, as I am.

Mark, you had it right the first time, I am cheap. We have used the same container of carb cleaner for lots of carbs and it will melt the floor is it is spilled...

 

[Bonnewagon]

Crap- I'm cheap AND stupid. You have a full tilt shop- of course you have a carb cleaning station. Probably a nice bead blaster too. Heck, you'll have that baby looking better than new. If you do wind up with the '79, that's the last year I consider easily workable to any end desired. For some reason the '80 models fight me. Might have very lean air bleeds.

 

[pontiacgp]

The race shop is gone, they folded the team but we still have most of the tools and other products. Those 80's carbs are lean running carbs and i'm not going to be getting that 79 carb. They haven't got back to me about the wrong set of pictures and I am sure glad you saw that carb number. You saved me a road trip.

I finished this one last night....minus rear choke pull-off. I haven't rebuilt one in probably 15 years, and didn't know what I was really doing back then. This one was plastic media blasted and coated with Eastwood's carb renew paint (silver obviously).

I incorporated some improvements such as access to the APT screw (tapped for a 1/8" pipe plug), new idle tubes, TFE bushed throttle shafts, stainless throttle plate screws and electric choke. I also polished the accelerator pump and power piston bores, along with making a new check ball seat in the fuel well. If you blast one of these, be VERY thorough with cleaning afterwards. FWIW, those large baking pans are great for rebuilding carbs.

I also like to shop wisely and couldn't see myself paying what carb shops want for a couple of screws, a few strips of TFE or check balls.

I went through McMaster-Carr and bought 100 qty each of stainless hardware, a roll of TFE sheet, and 440 stainless check balls.

Throttle plate screws are 3/48 x 1/4" pan head. Choke plate and upper secondary flaps are 6/32x 5/16" pan head. I spent under $40 for all of that and will probably never build enough carbs to utilize all of it.

Wow Steve, that looks professionally done. You do nice work!

Wow Steve, that looks professionally done. You do nice work!

Thanks a lot, I appreciate it. Now let's see if it runs worth a damn. I'm going to fire it up today and see what I get.

Steve, since we have the same first name we must be related, let me know where you are so I can send my carb to my favorite relative for a rebuild...🙂
