Help! Autolite 1100 leaking like a sieve.

[Oregoon]

Rebuilt my carb today. Soaked it in chem-dip overnight, and put it back together in the proper manner: Passageways blasted out, etc.

Now that it's reinstalled, it is puking gasoline out the pump-diaphram and the float bowl/top-of-carb gasket. It has no dash-pot, or provision for one, so there's only the one diaphram. During my tear-down, I noted a rather sticky power-valve, if that's worth anything. Even when cleaned, it seemed inclined to bind a little, though when wet with fuel, it moved freely enough.

The carb didn't leak before, though it was a filthy greasy mess and idled at about 1400 rpm. Now, it idles as low as I want it to go, but it is squirting gas everywhere! Also, the throttle-shaft seems a bit loose. I'm wondering if it's not time for a new carb?

Any suggestions or help would be appreciated! I have a long history of bad relationships with evil carbs!

check the float height and for trash on the float needle seat.

Done and done and still leaking like an outhouse.

Did you put new parts in ? Should be no leaking, unless you used an old kit or something of that nature. The new gas often contains methanol ethanol which will eat up older carb kits rubber. However it sounds like you just reused what was in the carb, and if so, then you need some brand new parts, and preferably not NOS or old stock, but fresh new with neoprene or whatever that resists meth/ethanol.

Had the fits with the carb on my truck. Did a complete overhaul with all new internal parts. Fought it for 2 months. Ran like crap no matter what I adjusted. Switched carbs and everything is well now. Hope you had an overhaul kit. If not, sounds like you will need one.

[Oregoon]

I did use an overhaul kit, though it left a few things to be desired--like a new needle valve. Though it contained two, niether came remotely close to fitting and I was forced to use the exitsting valve. And I'm pretty sure there's a rubber-o-ring under the seat.

I think the culprit may be in sight...

Never saw a rebuild kit without a new needle and seat that would fit. Sure it was the right kit for your carb? Maybe you can get a new O ring?

Oregoon aren't you in or near Portland. If so I will look and see if the carb I have under the bench is an autolite. If so you are welcome to it and the Autolite 101 rebuild kit parts I have. I think I saved it for parts.

I am in Portland, and would welcome a parts-carb! The trouble (I think) is that the Autolite 1100 came in so many different applications, and for whatever reason, the Carquest kit I used didn't extend it's one-size-fits-all approach to include my carb. The directions showed the two needles and the replacement seat as fitting "1965 and up," yet my truck and motor are 1966... And they offered no other needles or seats in the kit.

I should be able to look this weekend as I am trying to clean up the "explosion" of slick parts that seem to be all over the garage. I will post when I find the carb.

Go to NAPA buy a needle and seat Echlin 23540 it costs 2.33 this fits the Ford Autolite Carburetor. Set the float to specs you should be good to go.

Thanks for the info! This will be the first order of business on Friday. Probably the only thing I'll buy all day. And if ras4434 has an extra carb, I'll certainly take him up on it. Can't have too many extras...

As for now, it's turkey time. Have a great Thanksgiving!

Nope, that's not it, either. Thanks for looking though!

My carb features a small, press in-seat with an O-ring, and nobody seems to have any idea where to find one. That part (Echlin 23540) is threaded, too.

In fact, all the rebuild kits I find here in Portland feature a large threaded version of my small, press-in needle and seat. Further compounding issues is my sticky power-valve.

This week, a friend decided to pitch in and pay the local carb-whiz to rebuild it for me. "Merry Christmas, I owe you one anyway," he says! While that's great, there's a few specific parts I really need, if I am going to get this thing together, and I will gladly pay for them.

Member ras4434 may have a core for me, but he's still looking for it (his shop sounds like mine!), and there's no telling if it's the same version I have. He's an awesome guy nonetheless, and is helping me out just to be nice. Hopefully, I can repay the favor!

Anyway:

1) I very much need the rod that connects the manual choke linkage. Mine fell victim to my 8-year old son, who clearly dropped it into a rip in the space-time continuum.

2) An air-cleaner assembly. My poor little Autolite wore a 6" filter when I brought the truck home. And yes, it was chrome! All the local yards are bare of such a thing, and I'd like to use something closer to stock.

If anyone has these, please let me know!

Many, many thanks...

PS: Very much considering a Weber 36/32 and a new distributor should this not pan out. Any thoughts on that route would be appreciated.

[bobenhotep]

Good luck with the carb. If it doesn't pan out, get a carter yf for a 1970 f100 with a 300 (if you do indeed have a 300). Put a duraspark II distributor on it and be done. This is the setup on my 300 (on my 63 truck). I got tired of having to look in museums for parts, and got a free engine. I had to figure out the cut and paste to get it to work, but it was totally worth it. Your struggles remind me of the stuff I went through with the 223 I had before, and I was totally happy with the upgrade, and only regretted not doing it earlier. Good luck either way.

OK, been working all weekend and should be off Monday afternoon and can get back to the "dig" in my garage. Dang it I know there is a one barrel in there somewhere.

This is what makes this a great board! I'm going to respond in kind and offer up my longbed trim if anyone is after it.

My truck bed was replaced at some point, and my cab never featured trim, whereas the donor bed did. While I like the trim, I think I'm going in a different direction. Plus that trim is spendy!

I measured the stroke with the trusty wire test, and it came out at 4", so it's the big ol' 300. Really wondering what crank might be in there!

Anyway, thanks for the info on the Carter. Should the current hassles prove too much, I'll go that route. Looks like an easier install than the Weber. Cheaper, too!

I did some research and it seems pretty popular. After doing some reading over at Classic Inlines, I'm strongly considering ditching the Load-o-matic anyway...

If you get rid of the load o matic I have most of the info for what you will need.

[Oregoon]

The Load-o-matic is definitely going away, since the Autolite is pretty much junk. I went by the carb guy's shop and it seems that I would need a ton of milling and drilling to make it work, as well a new power-valve, choke assembly and accelerator pump. It's just flat-out used-up.

While he'd be glad to do he needed work, it's hardly worth the money. Even in great condition, it's no great shakes.

So, everyone is advising me to ditch it in favor of either a Carter, a Holley, or a Weber, and now I'm in the market for a carb and a distributor...
