Re: 2.8 carb rebuild ??

an aftermaket carb&intake would probably be cheaper.

Re: 2.8 carb rebuild ??

if it is done right it should be okay...I mean a Holley 2bbl is gonna set you back $300 alone...maybe ask around to local shops and see what they would charge for the rebuild...

Re: 2.8 carb rebuild ??

I had one rebuilt at a local carb shop (with a good reputation) and it runs great - no leaks. Wasn't all that pricey either.

Re: 2.8 carb rebuild ??

I've rebuilt a couple of carbs i just want to make sure it's worth it. I was goinf to rebuild the carb on my samurai but those things are a POS and even if a 50year vet rebuilt it the truck still wouldent run the same

Re: 2.8 carb rebuild ??

"because it will leak" ??

It will leak if it's already leaking. You sure you've rebuilt a carb before?...if so why are you asking this?

. Yep, this is exactly the reason I swapped to the Holley. My original was toast and not worth rebuilding. A few will argue this with me, but I don't think they have experienced th Holley with the intake. My mileage actually improved if you keep your foot out of it (hard).

I think the truck is overall better. However, if you can build it cheap you might be better off. No doubt the Holley is the way to go vs buying a new or rebuilt one dollar for dollar imo.

Re: 2.8 carb rebuild ??

All stock carbs leak? Holley's don't leak?

Jimmy and I are on opposite sides of this fence...but it's ok, he's been wrong for a while now

But seriously, Jimmy how can you really suggest the Holley route? He's looking at spending way more than you're leading on.

1. carb kit could run you $20 or so.
If the carb is ok and you know what you're doing....then bam - done.

2. a remanufactired carb with a core return will run you $180 or so. www.guaranteedcarbs.com. Off with old carb, on with new.
Bam - done.

3. Holley is likely gonna run ya $300+, on top of the new intake you'll buy (more time/work there as well).
Then time to rig it up for usage.
Then, sorry but there's worse mpg with the Holley option compared to staying with stock.
Then...bam, done.

If time and $ are a factor....is it really a tough decision here?
Why not have the carb examined at least to see if a rebuild is better? (option 1)
If not, option 2 is a lot less $ and work.

With option 3, once it's complete...you then get to incessantly reply to others how they should do what you did and get a Holley.

*Jimmykick - I kid because I care.

X2 for a float. That $20 "carb kit" won't have one. It probably doesn't have the throttle shaft bushings and reamer you'll need to stop the vacuum leaks at the worn out shaft. So.....Bam - some things to think about.

Yeah, the separate float game is kinda BS...but that's how they do.
That should be in a carb kit (really).

A quality kit should have the bushings, you can always ask.

Note: there is no info stating the carb IS leaking btw (just a rough guess from a buddy it sounds like). Heck, there's no info that it's in need of a rebuild for that matter either. Yer gonna have to check it.
What's the problem to make you ask about a carb rebuild btw?

this is what I have to do to start it after sitting over night.
stick the gas to the floor (the whole time while starting)
it turns and turns and turns almost a minute before it even start's to fire once it starts to fire a little i still need to keep the starter going because it's just not there yet.once it finally fires enough to let off the key I still have the gas to the floor while it chuggs its way to an idle and then to a rev and thats when i let off the gas and start to feather it to keep running until it will idle by its self. BUT once it warms up i can start it up without even touching the gas pedal. then if it sit's for say an hour or so in the 35* wheather i have to go through it all again. it also backfires when i rev it up

yes the bad carb did come from a buddy of mine that has a 2.8 that had a bad float. I'm going to dig in tomorrow first off i'm going to replace the fuel filter.then hit it with the timing light

Re: 2.8 carb rebuild ??

Hmmmm...carb from a friend, but did you replace the known bad parts (float)?

Still, ya know, I think I'd be changing that mech fuel pump, def fuel filter (cheap-cheap) AND may as well rebuild the carb. Your description is coming from what one would do to start if the carb was flooded i realize...but it's also a possible sign of a worn mech fuel pump too.
Is it orig ya think?

Before I got the reman carb I replaced the mech fuel pump after having like symptoms, and the starting issue was resolved. I knew mine was orig so i didn't test it. Now it's just pump the pedal a few times before turning the key, then start and let her idle till warm. Pretty standard.
They don't last forever (although longer than an in-tank) and they aren't all that much (don't have to be that is).

Not too diffcult to replace btw, just gotta get in there.

While we're at it, how's the choke operating? When it starts, is it going into high idle and then subsiding when warm?
Separate part once again, not too crazy to replace (drill out old rivets, replace part for proper operation, use screws instead of rivets (or re-rivet if you want).

Re: 2.8 carb rebuild ??

Another cheap-cheap but def worth replacing - the vac lines. They ok?
In fact, I'd do each in order of least expensive on up.

Check out www.rockauto.com btw for parts (excell service imo).

Re: 2.8 carb rebuild ??

Doh, sorry - don't mean to add to your cost and work, but don't forget the vacuum pulloffs (yep, they go bad as well).

So carbwise, if it comes down to this as a culprit...maybe weigh in on the cost of a reman ($180-190 at the link I sent, good company btw) vs. rebuilding and more parts (pulloffs, choke, float, etc) yourself?
Might be cheaper, less time consuming to get the reman.

Replace the mech fuel pump for piece of mind yourself, espec if I suspected it was orig. ACdelco or even a Carter... to a cheap airtex to get ya by (since you might be upgrading it all anyways).

but she still needs work
I started ripping everything off the extirior badge ,wing,mouldings stuff like that.

but here is what it looked like when i bought it.I did run into a huge problem found out that the front of the roof had been caved in at the windsheild and the roof has a ass ton of bondo in it. I might have to cut it off and get a donor

Re: 2.8 carb rebuild ??

Bamm - $2.00 part!

Cool. I'd replace it once a year min maybe.

* if it were me I'd still consider a carb clean or at least run some seafoam or Lucas fuel sys cleaner, replace the bad float you mentioned, and I'd check or flat out replace the mech fuel pump for piece of mind.

I hear ya on the inlet/line nuts. I pipe cut my fuel hardline end, got a different fuel inlet with a tapered end (screws into carb, holds spring and paper fuel filter), and routed fuel line around and back into the carb (even added a 2nd larger fuel filter inline). Less fighting for clearance in getting that inlet out to change fuel filter).

Yeah, that stock carb inlet is a real f*cker. I remember having that issue with mine and cutting it like Joe did. I think I might hae actually had a pinhole in it....That's been so long ago I can't remember.

Joe....I love you man! We gotta get together one day, have a beer or two and argue about our carburetors. Then I'll let you drive my truck. . Nah, you are probably right on. He probably is better off rebuilding it anyway...You are right, it is a lot cheaper. I wasn't "advocating" that really. It's just an option. I probably wouldn't do it either if I was on a budget, or wasn't really looking for an upgrade in performance. I'll admit it was more expensive, but I have no regrets because I wanted better performance and the mileage didn't suffer. I knew I'd be putting 3.4 and spending some $ on this truck, so I didn't mind. Check out this video before I pulled the 2.8 with the leaky freeze plugs. This is pretty much a cold start with the Holley.

http://www.youtube.com/watch?v=-draPb2oiiI

For the record, it wasn't really that hard putting it on. There wasn't really any "rigging". The biggest problem I ran into was the sh*tty instructions that came with it. I had to cut a little groove into the throttle bracket to make it work and find a throttle cable that was a shorter working length. It would have been nice if they had included that info. Otherwise it wasn't really hard at all. It came with all the necessary goodies and even told you the right kickdown cable you would need.

I would still like to see how the stock carburetor does on that Edelbrock intake. As I go along, I might even do away with the carburetor all together and go EFI and slap a throttle body on top of that intake...That might be really cool!!

Joe, we gotta do that beer sometime....seriously!

Yeah, maybe we'll do some homebrew I have. Don't worry, it's from a "kit", and it is actually pretty damn good.

As far as the truck is concerned, it's still no racecar, but it does get down the road real well. Even with the 3.4 that's not what I am after. I just want a neat/nice old truck that drives like a new one. One that has some mild mods and is streetable. Hence the reason I didn't put a V8 in it. Now that is some rigging I don't want any part of. I hope that the the performance is really good when the 3.4 project is complete. I'm really starting to get excited about it too. I'm almost done cleaning the frame, and next week will probably start wiring up my fuel pump if I am satisfied with how clean the body is under there. I really am planning on taking my time with it though. I've got way too much money and time in it now to slap it together.
