Maybe float is not adjusted right or stuck. I'm can't remember but I think the float height is suppost to be 9/16. Maybe someone else knows for sure.

So I adjusted the float and it still flooded the carb so I take the top off the carb and run it to see what was going on, and when I did that when i started the jeep just fuel just started shooting up to the hood a lot of fuel.. It seems like the pressure is too high but I never changed any of that

Are you still running the stock mechanical fuel pump? What about the fuel filter before the carb? It needs to be a one inlet two outlet so the excess pressure can bleed off back to the tank. If you have a 1 in/1 out filter that's probably the problem.

Can you snap a pic with the top of the carb removed? Preferably one from fairly close so we can see the float and needle.

That is probably what it is It is a 1 in 1 out with stock pimp and Ill take a picture when I get home, when I got the jeep it didn't have a bleeder line, should I run one back to the tank?

Are you sure it didn't have a return line back to the tank? Check the inside of the drivers side frame rail. There should be one brake line there feeding the back brakes from the proportioning valve, and one fuel return line.

But I'd say that the problem you have is due to that filter.

sorry for the delay everyone, my DD has been putting up a fight! but got everything going just want to make sure i have my vacuum lines right, i have my pvc going to the port in the back of the carb, distributor advance going the the port on the passenger side below the choke, i do not have an egr or anything. there are two ports that i have plugged because i dont know what to do with them, the one on the back i believe it is the bowl vent and one on the front drivers side. does this sound right ?

No power brakes? Best bet is to just try it out an see what happens. Try putting it under a load to see if it falls on its face or chugs along.

Yes I have Power brakes but that vacuum line goes in the manifold itself where it originally was

It's been storming all afternoon, but Finally got her started up got the idle down but something is definitely off, I belive my timing out of wack there is a lot of pinging and it seems like it is having pre ignition.. Can a new carb cause this? And I will post some pics of the set up soon. By the way does anyone know how to get pictures posted right from my phone? I used to be able to but now it is saying attachment exceeds limit or something like that?

The pinging could be a lean issue.
Everyone likes to say 1.08 carb for a 258, do you know that if a very small carb and very possible it is to lean.

Okay thanks for the tip, and I've done some searching about timing, but Does anyone know where the best place to hook up the vacuum gauge to set it via vacuum?

I think most people use the brake booster port. But I've been known to be wrong.

Boil it in lemon juice. Really ? I am sure you are serious but can you say more about that procedure ?

Old timer trick to clean carbs.

I saw it on an ATV forum, and did it on and old early 80's Honda Generator carb and a Honda Foreman carb. Worked great, so I did my MC2100 in it too.

Get a bucket, toss it on a campstove, fill with lemon juice, and boil your carb parts in it. Get's the goop out.

The generator (old ES3500) had been sitting for probably 5+ years. Gas was varnish, and carb was totally gooped up.

Lemon juice boiling worked great on it. LOT cheaper than carb dip, and you can dump it out in the yard when you're done.
