Would you adopt a cat that hasn't been tested?

I have 3 foster kittens at the moment. I rescued them, but have teamed with a local no-kill foster rescue program to foster them and get them medical care, etc. I've had them for a little over a week now. They've been to the vet, they're off their eye medication, and they've become far more social than they previously were. They're only about 3 months old and cannot be tested for FeLV or FIV until they're 4 months old (the next vet appointment I'm supposed to take them to). I haven't posted the kittens on Petfinder yet because I didn't feel they were ready to be adopted until they were done with their meds and more social and comfortable with human contact. Now the rescue seems to really want me to put the cats up on Petfinder and bring them to showing at the pet store that they do each week. However, I am now concerned with adopting them out without knowing if they are positive for FeLV or FIV. I know it isn't super likely that they have it, but I worry since they lived their entire first 3 months outdoors and encountered who knows how many of the several stray cats in my neighborhood. Their mother also lives outdoors 24/7 and I don't even know who the father is.
I'd feel horrible if someone adopted one of them and took them to the vet only to discover they had one of these diseases. It's bad enough that their new kitten has a horrible illness, but what if they no longer want it after that? Even worse, what if they already have a cat at home and he/she gets infected?
I don't want the rescue to think I'm being reluctant in posting the cats or getting mad at me for not trying to get them adopted asap. They're mainly a dog rescue, so I don't know if they really think about this aspect of cat adoption.
So, I'm asking my fellow cat lovers if you would want to adopt a kitten, not knowing if it has FeLV or FIV?

Did I say I was waiting until they I got them fixed to have them tested? If so, I didn't mean to say that.
They cannot be tested until they are 4 months old because the test can be inaccurate before then. The kittens still have a great deal of the mother's antibodies until they are about 4 months old. This means that if the mother has FeLV and the kittens don't, it could still show up as being positive for the kittens. Likewise, if the mother doesn't have it, but the kittens do, it can show up as negative, etc. I am not making this up; it is all according to the vet. I asked about testing right away since I have my own cat who I don't want getting any diseases from these guys.

By the way, I'm mainly asking this question to prove my own point about not feeling comfortable adopting them out until they are tested. I can be a bit over-protective with animals, so I'm trying to get some backup. Of course, if you wouldn't care about the cat being tested, I'd also like to know. If I were adopting a new cat from a rescue, I'd expect it to be tested. I just want to make sure others feel the same.

While it is popular belief that if the mother has these diseases, the kittens will too, this is not always the case. While it is common for a mother to pass it on, it does not always happen.

The problem is that I don't believe this rescue has any policies about bringing cats back and what not. They don't have many strict policies about cats since they are mainly a dog rescue. They started off as a dog rescue and have taken on cats since they are always getting so many pleas for help for cats. Anyway, they don't really have a say in who adopts the cats-only the foster parent does. I still have to have the people fill out an application and everything, but I decide. I don't really know if this means I can make my own "return policies" or not.

And I know that these illnesses are rare in the scheme of things. But as I mentioned, I only really worry about it in these guys since they lived their first 3 months outdoors, their mom is an outdoor cat, and I don't know who their father is. There are many stray cats in the neighborhood that seem to gather around their former house.
I've also seen apparently healthy kittens have these diseases. These guys looks perfectly healthy now, but I cannot know for sure.

Yes, I do know it is rare; yet, there is still a possibility. I know people who have taken in litters or a single cat into their home that turned out to be FeLV+ or FIV+, despite the low chances.
I will probably put the cats up on Petfinder and if I get any applicants before their next vet appointment, I'll just inform them that they haven't been tested. That way if they want a cat that's been tested, they can move on. I've already decided that I am going to tell adopters that I will take the cats back, no matter what the reason. If something goes wrong with these cats and the new owners don't want them, I don't want my babies ending up being dumped at a shelter. I call them my babies, adopting them out will be impossible!

Thanks to everyone who answered. I realize now that I probably should have asked a different question. I love cats very much, like everyone else here. As such, I often take in cats in need, knowing they've probably never been to the vet. However, in this instance, I'm not talking about cats we rescue off the street or those rescued from a pound right before the poor cat is about to be pts.

Let me ask this instead. If you were fostering kittens in your home and you had no time limit on how long you could keep them (i.e. nothing was forcing you to get them out by a certain date), would you want to wait to get them tested before adopting them out to somebody? If you were the rescue that I was working with, would you think it silly for me to not want to adopt them out until I had them tested? Keep in mind that everyone that applies to adopt these kittens will not be like many of us here that have experience with cats, are willing/able to keep them separate for some time, or are willing to deal with certain health problems if they do arise.

Obviously this isn't the same as rescuing a kitty in need off the street or one from the pound that's about the be pts. This is paying $90 for a kitten from a no-kill rescue where the kitten has a nice warm foster home to stay in for as long as he/she needs. (I'm not even sure that if one of them were to get adopted before their next vet appointment, if the rescue would pay for the tests. I know they'll pay for spay/neuter. I need to ask about this.) Of course, there are people that want a kitten as young as they can get them, so they won't really care. Yet, are those the first choice people I'd pick to adopt them...no.

The rescue does have the funds. The kittens will be tested at their next vet appointment, which is when they're 4 months old. They're currently about 3 weeks away from that point. They can't be tested until they're 4 months old.

It seems that most people feel the same way I do. I suppose I can post them on Petfinder now, but make a disclaimer that they have not been tested and that they will not be available to go to a new home until after the tests have been done. This way I might be able to line up homes for them so that once they are tested and (hopefully) the tests come back negative, they'll have a home to go to right away.
