MORE more help please....

[hasa68mustang]

well I Thought I would recheck timing, get gas, play with some of the screws on the carb try to see if I could get the car running better and make sure the choke wasnt part way on...well I drove for a good mile or 2 and it WOULD NOT hesitate, bog, anything.... ran like a top.... so I got to our garage and checked the timing was set at 14*TDC and then I left for some reason... I dont know why.... and the car had idled for a bit and gotten warmed up and then it had its hesitation issues... well I saw one of my friends at a ligth that I Was turning at and he was with his mom and little sister in their buick family 4 door and he laughed and asked if I wanted to race, well I couldnt I was in the turning lane and it was purely meant as a joke so I put it in neutral and revved it up a bit not but a little past 5k and let off and it died... so I Tried restarting.. nothing... I could get it to idle VERY slightly but as soon as gas was applied it would just die... or woudl idle for 5 seconds or so and die... so I was left with trying to push my car across a highway... I tried.. made it 3 feet before the crest and with adrenaline and everything I couldnt do it.. so I was stuck blocking a highway with a green light... so out of the blue some guys run over and helped push and I thanked them and I got the car off to the side of the road... I tried a couple more times and looked in the rearview and all I could see was smoke everywhere... I almost crapped myself... so I went and opened the hood and inspected the head and made sure everything was ok and not leakign anywhere and I took the air cleaner off with my lucky 1968 penny and saw the choke was on all the way so I turned the lever got in the car and it started and I drove it home everything fine... except it still had the hesitation probs.... sooo what would cause the choke to do that? it has happened one other time when I put the carb on for the first time... could that have something to do with the bogging? so in the end I now know not to show off... and to leave your car stock... HA! so any help would be greatly appreciated, Thanks, Tommy

Now myself personally I never use a choke and to make sure I never have the problem that you explained, mine is strapped open with a zip tie!

Dont know how it got shut....maybe in the heat of the moment by showing off to your buddies you might have bumped the lever?

Is your choke actually hooked up or do you just have it open? Is it a manual choke Holley? It has a indent in it to manually hold it open but it will flop shut on occasion as you described if it isnt wired or held open somehow.

Thats never happend to me though!

Later,

Doug

yes it is the manual choke and it USUALLY stays open but did it one other time when I took my car out to test it and it did like it did here but it wasnt open as far so it just sortta sounded liek it was missing... I will probably do something with it to make sure it doesnt turn on again... I once hooked up a calbe from the local auto parts store but it was too cheap to even move the lever back... so I unhooked it and went on with life... I dont bother with it... if only you guys knew how scared I was both times... thinking I had did something terribly wrong... but in the end I had to open the hook move a lever get in start the car and go on with life...

I went one more and completely removed the entire shaft and butterfly!!

I went one more from you and milled off the horn too

Hope you kept the number from the horn so you can buy a kit!

If I were you I would order a quality manual choke cable from a Mustang parts vendor. The high performance Mustangs had manual chokes so you can get a cable for one of those. It is much more substantial than a cheap aftermarket cable and even if you don't use it to control your chke it will hold it open and still be there on a cold morning if you need it.

I live in florida... a cold morning... your sillly... I think it got into the 70s last year.... Ya I suppose with winter comign around I proabably should get one... the problem I was having with my cable is it wasnt strong enough to push it past that little notch or whatever thats supposed to keep it open... I know holly makes one I dont care for orignality...

 

[CobraSix]

YOu don't need a choke in Florida...come on!

I ran an entire winter in Rhode Island (drop it every day) with my Autolite 1100 with the choked strapped open because my autochoke did somethign similiar to yours, just all of a sudden the butterfly wouldn't open up. If I recall correctly, it ended up being one of the springs that broke randomly and wouldn't open the choke up.

I would make sure you have it wired open or something not jsut flapping. I left the choke open on my 5200 this summer with no linkage hooked to it but they are pivoted from about 1/3 out so it ALWAYS stayed open.

Thats weard
You do know you have to step down on the gas so the idle screw can go past those notches on the fast idle cam?? and you can pull the choke close you can't just pull the cable and expect it to close the choke with the spring tension pulling the linkage closed up agianst the fast idle cam notiches.. the notiches have a squair edge and the screw is flat on the end it would be like trying to push a box up a set of stairs..
You useuly pull the cable to set the choke and push it to open the choke is your cable on the right side of the carb?? If you have no cable on it you well have to strap it open or sometimes it well get pulled closed... by the vacuum of the motor..

end.

Could the choke have been partly on when you drove it then. If so it would suggest that you are to lean. If youre to lean then you might look at how much accellerator pump vollume youre putting out, alkso you might need to richen up youre mixture. How are your plugs? Are they white? You could try putting the choke back on partly on a cold engine to see if youre condition is repeatable. A cold engine needs mre gas than a warm one, with the choke part on it would richen your mixture and improve engine performance but when the engine warms up it would make the mixture to rich and block your airflow.

For now either wire the choke open or remove it. That should help with at least on of the problems of flooding the engine.

As for the hesitation. If wiring the choke open corrects the issue go have fun. If it doesn't you may need to work with the size of your accelerator nozzle and maybe even the power valve. In most cases a hesitation is caused by running lean. One simple way to check this is if you give it the gas slowly does it run ok. If you give it the gas quickly it hesitates then it is lean and you need to go up a couple of sizes in your nozzle. Also since it has been loaded up pretty heavy you may want to throw in a new set of spark plugs.

 

[XFlow_Fairlane]

I konw it sounds dunmb.....but is the accel pump lever in the right location? I know I have tossed on my fuel bowl a couple times with the arm not lined up and it wouldn't work at all.

 

[hasa68mustang]

I have to goto work I just stopped home to see if I had any messages and check this post... well here is the way it looks and the choke is on the back side... again today after taking a corner and giving it gas it stalled... I had to go though because some idiot was flying down the road so it wasnt liek I was peacefully driving... heres the pic...

 

[hasa68mustang]

WELL... again with my no luck... I pulled the plugs all were whitish and look just like they should according to my chilton. BUT one did seem to have some oil on it and another had the arm piece thingy bent in so that it was gapped at a little under 20 thousandths? so I took the oil looking one and cleaned it and place it in another hole to see if it was someting that was temporary... so I put all the plugs back in started the car... and it was missing, I looked at the plugs while it was idling and I coudl see sparks comign from the #3 plug... so I turned the car off made sure everything was secure and ok and it was the same. I dont know if that was my plug that was bent and when I gapped it it isnt working correctly or? so I guess I need a new plug or a set of them... so tomarrow I am stuck with my dads truck... anyone have any suggestions as to which ones to get? I have the standard autolites in it now... would I benefit from a better plug? I also hooke dup the choke cable and made it so that the choke couldnt come on and I drove home and it never got hot, same with the way to our garage to check the plugs... then this happened... ok.. so the first time it hesitated was when I drove my girlfriend to school.. since then I have broken down 2 or 3 times... in 1 week? almost daily... is my car jealous? does it think I am cheating on "her"?

You regapped all the plugs, right, and checked the bent one to see if it sparked? :wrench:

I did regap them while I had them out, BUT never checked for spark... I knowmy dad has a tester somewhere and I Also know I have more plugs BUT I have no clue where both are... I know it sparks because I could see it in the hole so something wasnt right...

If its a manual choke, it can be manually adjusted.

Try this. First, the idle air screw, turn it all the way in, and then 1 1/2 turns out with the car off. Make sure it hasnt been running and is in a cold start condition.

Then, start the car, and unscrew the choke cable to the screw that holds it. Make sure, first, that the choke is pulled about 1/4 on the interior.

Adjust the choke manually. Essentially, with one hand on the throttle linkage, and the other holding the choke butterfly held with the other, move the choke butterfly back and forth. Make sure its unscrewed properly from the cable, so it slides in the cable.

Its trial and error from there, but when you move the choke a minor bit, youll hear its sweet spot and open the throttle QUICKLY, to test that response is there.

Once you find that sweet spot, test it by moving the butterfly around up and down more. Youll see, with throttle response, that its not responsive. Then find the sweet spot again, and take your time. You may not get it right the first time, I always drive it a block and check it, then pop the hood and get it better.

By that time its warm condition, so tighten the little screw on the choke cable, and get in, push the choke button on the interior in, and take it for a spin.

Should take 2 or 3 times to get it perfect.

Essentially the "choke" does just that. Under cooler conditions, more oxygen molecules are compressed in the air, comparitively to a hot summer day. So it "chokes" the compressed air from coming in, so the air to fuel ratio can be correct. Otherwise, theres too much air in the cylinder, and it runs improperly. The choke can also make it run extremely rich if its adjusted improperly, anotherwards, the butterfly is closed too much, not letting enough air in, and there would be too much fuel in the air fuel ratio=rich condition. White plugs, black smoke out of exh.

I feel youre running rich, which would be a tell tale sign that the choke is malajusted, so it is constricting the engine from recieving enough air.

The smoke was black, right? Thats just unburned gaseous fuel. Doubtfully you have blown anything up, and well try to help you not to blow anything up.

Good luck. Read and re-read until you get it better, then apply it. Or print it and bring it out to your car.

Been stuck in the middle of a highway before. EFI cant be fixed instantly.

You live, you learn. I hope you get it to correct.

HI
If you had all the plugs in and you could see sparks comming from the #3 plug then maybe its wires you need?? or new plugs if the porclin is cracked and the spark was comming from that.
