New carb?

[Ktmrida4life]

I think you should listen to what's been said before. Stop trying to start that car! You could burn it and your uncle's house down. What is your reason for trying to start it? Is your uncle going to let you drive it? Doesn't sound like it. Don't waste time or money putting a carb on this car until your uncle comes to his senses and lets you replace all the fuel lines and have that tank cleaned and the hole soldered shut. You will just ruin the new carb by flushing all that junk from the tank and lines into it.

Im not the one trying to start it! He is. And your right, he probably wont let me drive it.. and knowing him, hes not going anywhere in it. Hes a hermit.

1st thing is, I would highly suggest you invest in a "FACTORY SERVICE MANUAL" for your specific year, make & model of car... Educate yourself some on these "older cars with distributors & carburetors".... Everything your asking, is very well explained in them, also drawing & schematics for referring back to... Good luck

I will get one. Thanks.

Factory service manual has been ordered.

Uncle finally let me take the carb off tonight since its not doing any good sitting there. Figured out that it DOES hold plenty of gas, and it is leaking gas out of the 2 little holes in the back of the carb which I assume are an overflow of some kind?

Whatever the issue is, its causing the car to flood. That may be why once it finally does start, there is a lot of white smoke for a few seconds. Took the choke thermostat off as well since the choke hasnt worked in a long time, and readjusted the spring tension. It should work now.

Going to thoroughly rebuild the carb again myself. It is a Carter 3859S. This time I am going to get it as close to spotless clean inside and out as possible.. does anyone know any tricks to getting a carb real clean?

Once disassembled, can I soak metal parts of the carb (as well as the carb housing) in carb cleaner for a few days? Will that hurt anything?

Had my avs done recently. The guy lightly bead basted the top,base, and plates. Not sure if he bead blasted it before or after he dipped it.

Guess these avs's aren't so easy to rebuild or just bad luck, the accelerator pump isn't giving it enough fuel shot. Took it back to the guy and waiting to see if its repairable.

Wow that is clean!

I think Im going to buy that along with some carb cleaner tomorrow and see what happens. When cleaning/rebuilding the carb, does the whole thing need to be disassembled? Ive taken it almost all the way apart before, pieces everywhere.. but I left the throttle shafts/butterfly valves/etc and all that in. Should I take them out as well? Any special tools needed to do so?

Gotta convince my uncle to eventually let me pull the tank. He is worried I am going to hurt something when I remove it.

leave the throttle plates in place.everything else should unbolt.make sure to blow air,or at least carb cleaner,through all the holes to clean out after dipping.double or tripple check both float measurements acording to directions in kit.most common problem rebuilding carter designed carbs is float settings.

This is a different carb but it will give you a general idea of howto do it. http://www.forabodiesonly.com/mopar/showthread.php?t=184531

Got the carb apart, MAN its FILTHY! Dont know how it was even running. Bought some carb dip stuff and let it soak for a bit and got everything clean. Used the ultrasonic cleaner on the smaller parts, and it worked, but for some reason it ruined one of my floats. It now holds liquid.. gotta buy new floats. Carb is way cleaner than before. I took off some of the linkages on the side and cant quite figure out how they go back on.. gonna take some trial and error.

Do I need a fuel pressure regulator for any reason? Stock mechanical fuel pump (although brand new)

Also, does anyone know a good way to clean the gas tank while in car? My uncle wont let me remove it for whatever reason... about 20-30 years ago he drilled a hole in it and drained all the gas out, and capped it with a self tapping screw. I removed the screw and drained all the gas.

It is GREEN!!! Like antifreeze green. What the heck could cause that? Is there a decent way to flush out the tank with it in car? Want to do this before I get a new carb.

There are usually only two answers for green gas. Since it's so old, it's likely just a product of evaporation and oxidation. Some people have found their gas to go green, or other colours like dark brown. The other possibility is that it wasn't automotive gas in the first place. Some aviation gas is dyed green, and some people have used it as race gas.My friend used to stop off at the airport for his race car and got green gas.

^^ Dont think his is race gas.. its just OLD


Does anyone know if all carter afb floats are different or are they all the same? My carb is a 3859S, trying to find new floats..

 

[Ktmrida4life]

Edit- Found new floats on ebay.

Once I get the carb rebuilt and back together Im not hooking the fuel lines up to it until I convince my uncle to let me pull the tank and clean it real good. Then Ill put some fresh gas in there, and turn the car over a bunch and make sure its coming out clean. I know for a fact that its filthy in there...

Wondering if the float that doesn't was the flooding problem. If your float is brass, I would think that any AFB float would interchange.

It very well may have been. I thought the ultrasonic cleaner I was using caused it.. I was only using vinegar/water though, dont see any reason that would hurt it. Didnt hurt the other float either.

Talked to my uncle a bit more tonight, still cant convince him to let me drop the tank to flush it out. It needs a new sending unit/pickup anyway.. he says "we could put an inline filter on it" which wont do anything IMO except make fuel delivery worse and still deliver potentially crappy dirty gas.

He is worried I will hurt something removing it. There is nothing to hurt AFAIk. One rubber fuel hose to undo, one wire, bolt in the trunk holding in the fill up tube, and the bolt holding the strap and the tank drops down. Nothing to it... just cant convince him

does he understand that anything you "hurt" can easily be replaced?i cant imagine how bad it looks in there if your carb is so dirty inside.you might tell him that an inline filter will just plug up in no time and cause the car to stall out.

If he mentions it again Ill tell him that. Yeah thats how I see it as well. There really isnt anything to hurt, I guess hes just worried it wont go back together. Probably because I took the exhaust off this same car about 3 years ago to replace that, and it still doesnt have pipes... apparently no one sells a kit that will bolt on (except for TTI, 700$) and he wont have it taken anywhere to put one on.

I wish I would have taken pics of the inside of the carb.. it would have made you all cry. It looked like there was green seaweed stuff everywhere inside it.

I told my uncle that if I messed up anything pulling the tank, that I would pay for it. He asked me to make sure all the parts were available incase something did get screwed up and I ensured him they were. Pulled the tank, sender unit is shot. Float was gone, just a rusty wire hanging down.. inside tank you could see where gas had sat, and hadn't sat. There was a thick layer of green sludge where the gas was sitting and surface rust everywhere else.

Spent literally all day trying to get the tank clean.. about 30$ in cleaning supplies to no avail. Its cleaner, but still rusty and Im still afraid its no where near as clean as a gas tank should be. Uncle agreed that we should just replace it.. so ordering a new tank tomorrow along with a new sender unit.

Does anyone know if Spectra CR12B is the correct tank for this car?

 

[Ktmrida4life]

Ordered the tank.. ordered the new 5/16" sending unit as well. Didnt buy a new tank strap, I just tried to clean up mine and painted it black.

New carb floats are here, but still cant do anything because carb kit is not. Should be here early next week. I was looking at some of the carb parts today and they are still pretty dirty. Hoping they just arent too dirty to work properly because Ive done everything I can to clean them.

a light scrub with a toothbrush and your dip should clean them up good.anything that is too hard you could get off with a dremel tool and fine wire brush if you are worried about it being too dirty.

 

[Ktmrida4life]

OK.

Also another minor thing that happened.. I tried to remove one of the throttle plate screws for whatever reason, and I didnt know they were staked on the other side. Needless to say the head broke off and the rest is stuck in the throttle shaft.

Could I take a little JB weld and smear it over/in the hole to keep it from backing out, or should I try to use a very small drill bit to remove it? The latter would be the correct way, I may give it a try anyway and just be very careful to not bend anything.. and if I can get it out, I can replace the screw.

Got the new gas tank today, its purdy! I think I might clear coat it to try and keep it from rusting.

 

[fatecaptured]

New gas tank is definitely the way to go. I believe the straps (mine at least was) stainless steel. The only reason I replaced mine was because I wanted new ones without undercoat all over them. The j bolts are harder to save, mine were pretty bad.

That sux about the carb. Hope u can fix it. There is always cheap parts carbs on ebag u could buy a $20 carb for parts. Good luck man.

new tank

good decision
