Why did you adjust the floats? They hardly ever need to be adjusted.

As far as the white milky stuff goes, you may wanna take the carb back off and make sure to clean the hell out of it with carb cleaner. Personally, I would take it to a shop and have it dipped in a carb tank.

i cleaned it 3 times now i know there nothing in it and the float needed a little help i did not mess with it too much. i have the perfect i mesured it over and over agian!!!

and by: the i mean IT

lovintha7

when you supply fuel to the carb, where is the fuel level in the float windows?

psh you aint hip

half in front and 1/4 in back

lovintha7

You're gonna want to adjust the back one to half. You want both sight glasses around the half way mark, possibly 1 or 2 mm higher.

would this make my idel at 2000? and none of the set screws are making it drop soo whats going on there

High idle is typically a sign of a vacuum leak somewhere. Good luck with that... Make sure your float bowls aren't overflowing into the throats of the carb (due to bad float adjustment or sticking needle valve)...

psh you aint hip

welll im still not sure sooo i pulled it again and the back bowl is set perfect but its still only getting 1/4 full sooo i dont know there and i could not find a vacuum leak i study and study last night on my car to find something sooo would a vac. line put in the wrong place do this?

Kentetsu

Maybe that rear float bowl is running low because the fuel is leaking past the needle valve?

psh you aint hip

that could be is there a way i can tell? and i got it running again last night and then exhaust started glowing red sooo i think its clogged. but who knows any input will help!!!

When I got my carb rebuilt, the bolts were not tight enough and vacume leaking was everywahre. I went in and tightened everything up and the idle is a bit high, but that is probly because I don't know how to tune a carb. It also sounds like the exhaust is clogged. Check the cat. they are usualy a problem.

Well that is my 2 cents, good luck.

Kentetsu

Glowing exhaust is a (almost) sure sign the you either don't have leading ignition or your timing is off. Fairly unlikely that your cat is plugged, even though that's usually the first thing that people suggest when they see a red header.

Ok, first off how was it running before the rebuild? The float levels will only be in the middle if the car is on level ground. If its on an incline then it will obviously be different. You need to get the idle lower before you worry about the glowing exhaust. The milky white smoke is evaporating fuel. Either shes flooding or something else is amiss. Did you mess with the idle adj or idle mix adj scrwes?

psh you aint hip

ok welll i pretty sure my exhuast is not clogged becuase it is straght through and there is really nothing to clog.
it was running very nice but it back fired like crazy and i had not top end at all!!!
and i di try alll the screws and its like they are not even ther soooi am going to just rebiuld the whole thing once again and see if i can see any thing

psh you aint hip

ok welll i found something in the bowls there are jets i took those out and one side says 100 and one says 92 does any one kno where these go? (like on what side) and thats alli can see sooo if u guys could help that would be awsome!!!

psh you aint hip

Timing.

psh you aint hip

ok welll i just done with putting it back on and it runs like a champ but it has a little miss and i need it to idel down just a hare and it feels like its going to run out of screw (on the idel screw) and im out of ideas but it runs alot better
what would it be holding from going down in idel and make it miss
by the way its running at 1500 i want it down in the 1000's sooo can you guys help out for the last time hopefuly

i played with timming and nothing!!!

Kentetsu

Difficulty in getting the idle down is usually a sign of a vacuum leak.

psh you aint hip

i sprayed carb cleaner all over it and nothing but i have it down to 1000 now but it still has a little miss sooo what could that be?

-bump-

As said before, timing. Get a timing light and set it to factory specs.

my girls first gen that she just bought is also having the same issues sadly guys im not to well know about the first gen i know more about the second gens so this is like a whole new car to learn ...


i noticed that her car idles really high also it stays at 2000 rpm i messed with the butterfly thing inside the carb while it was running and it made the car idle a little lower like 1500 rpm .i do know the car has a small vac leak but nothing serious.but should be taken care of ..her car is a automatic and i noticed when you change the gears in the car it hops then it will do something like a stall out. when she bought the car the only way to get the car started was to spary that engine start/ethenol into the carb and it fired right up. my point in this story.. there is none lol just wanted to share and btw

do you guys have pics? of the idel screw? and the other things to adjust the carb ect ect...GL

so you have the idle screw backed all the way out? and it only idles at 1000..... either your timing is too advanced, or the carb is pulling fuel from either the secondaries or maybe there is a small enough vaccum leak on the bottom of the intake manifold. do you have block off plates? do you have all emissions stuff? and either way... if it's idling nice at 1000 that is usually where you pull the most vaccum and i would probably leave it there. the slight miss may be your plugs are slightly fouled from all the trials of this carb you've been going thru.
