High idle and uses fuel

The problem started where once the car would warm up and you would turn it off and then it did not want to start again lack of fuel but figured out that if you turn it over four times and pump the heck out of the pedal it will finally start and run okay, but would stall out every time you try to stop the slowdown. Fix that with a PCV valve breakdown carburetor with carburetor cleaner found and fixed all vacuum leaks on the side of the carburetor. I believe it is a fuel regulator maybe I am told it is a discontinued item. I am having a hard time finding diaphragm replace diaphragm seems to run okay and some seafoam through the brake booster vacuum and a little in the carburetor seem to help a little took it on a test run down the road on the freeway just one exit over and then right back maybe four miles five miles. Got back to the house remove the air cleaner cover disconnected vacuum lines noticed the vacuum line going to what I think again is the fuel vacuum regulator on the side of the car there was off. So I put it back on and then I put the air cleaner and everything back on plugged all the hoses back in now the car idles really high no matter what I do I cannot get it to come down. In park and neutral it idles maybe around 12 to 1300 rpm's when you put it in drive it drops down almost to nothing and almost stalls out then picks back up to about 1415 hundred and then drops back down 289 - 1000. Sometimes eleven but very rough you know like as in the car like it wants to call you but it does not motor mounts are all brand new but it still takes quite a bit. I noticed also that it is burning an excessive amount of fuel. I think also I noticed on the back of the intake there is a looks like thermo sensor, but it had the vacuum lines going to the three of them as a matter of fact not sure what that is called, but it is a $70.00 part. I probably should not have, but I adjusted the little knob thing in the back a little bit into different directions tried to put it back about where I thought it was and then on the other side the little diaphragm thing. I believe it is for like when you turn the AC and stuff on idle do I turned it a little back-and-forth only a dozen as I have done today. I did not touch anything else no set screws or anything, but made no difference realized that there was a couple vacuum lines backwards. So I went through one by one and I am all right, but idle down to her about 1700 rpm's. So now it is 11 11 and 12 but when in drive still drops lay down his really rough sometimes while driving it seems to almost want to go real smooth, but it just does not. When accelerating it seems to do okay not much hesitation really time to time a little issue changing gears, but for the most part it does okay. That is pretty close to the most if you need a little more I can give but that is about my problem is really trying to figure out what is causing the idle to stay so high. I can rev the motor and sometimes it will drop down to almost nothing and then it goes back up to about 11:12 when I first start the car and I do not even have to hit the gas to make it start this carburetor spends over starts out as beautiful as it warms up for the idle picks up and then it gets up to the 12:13 or 11:12 and that is where it stays. Please help! Been reading and on this thing for three or four days now. Not a whole lot of blogs on it. Into a children's menu it has been something. If anyone can help please! Thank you very much.
