here's the engine with out any tin
now with the carb, how do i keep that thing from doing that? weird question but i want to know.
is there a piece i'm missing, i want to control this thing but can't it just moves down. like if i were to give it gas it would move down like in the previous picture and the flap in the top would be flat, or does that thing have something to do wit hthe automatic choke?

That is your fast idle cam. It's used for when the engine is cold. If your choke works properly, it will slowly move up allowing the lever to seat normally.

I'm wondering why you had a coat hanger with you at a show? Need to beat off the admirers?

The choke is on the other side. You hook up a wire from the coil that supplies a small about of voltage to the choke. It heats it up causing the cam to lift up.
When you go to rebuild your carb some day, you will find out how it works. It's a very simple system but it does the job.
Good luck!

My first thought at the engine pictures was "those are some clean heads..."

Alright, I have a question. I have been searching around here for days now. I have the same type of carb on my 67 Deluxe. It's a single port 1500. My question is... how do I adjust the Automatic Choke. I can't find how to do this anywhere. The "Idoit" book doesn't help much, and no one on here has seemed to describe this adjustment.
Can someone help me with this?
I guess my problem would help too. My engine starts up with every turn of the key. No Problem. But after about 3 minutes, it warms up and then dies. I've check all the idel adjustments, and the jet as well. It runs fine all day long, as long as I keep my foot on that gas pedal. Soon as I take it off, it dies. I've been reading about this problem over the last few weeks on many post's. But non of the replies have resloved the issue. I think the choke is the last item too look at. I just don't know how to adjust it???
Any help? Thanks |

You rotate the choke to adjust it.
Normally the choke should be correct when a mark on the choke lines up with an arrow on the carb. body but over time, sometimes the spring gets worn out and unless you bend the spring, you might to adjust it/rotate it to different location.
You can see the lines here
My choke is adjusted a little bit off, an NOS choke would probably adjust with the center ridge.

So you just unscrew the 3 screws a bit and turn it one way or the other to adjust it? I assume this is when the engine is off? After I turn it a bit, start the engine up again and see if that worked. And if not, turn it the other way or more the same direction?
Is that the idea, or am I way off? I don't see any marks on your carb or choke. Maybe I'm not looking close enough. I'll have to go home and look at mine. I've never noticed any marks on there either. |

what is the knob piece where the idle cutoff goes |
That is the solenoid connection. That's a really early one, like 62 and earlier only. Rare if you need it, lame if you don't.

Looks closely at the photos above and you will see 3 bumps on the carb. body. Your carb. may have 1 or more. There is a line on the choke itself so you know where to line it up.
You can adjust it while it's running, it doesn't matter. A good way to adjust it is to turn on the ignition, let the choke heat up. Watch it for a few minutes and make sure it's completely open. It should take a few minutes to totally open. Of course, it depends how cold it is outside on how closed it might be.

So last night I got home and found the marks on my choke. You were right, there are 3 bumbs on the carb and 1 notch on the choke. The guy I bought it from had set it pretty much in the middle. He may not have moved it for a while. I took it out to see how the thing looked... It was old and rusty looking. I got most of the rust off and plugged it in to see if it got hot. Seems to get plenty hot. Kept burning my hand while holding it.
I put it back on, started the engine, and after it warmed up when it usually starts to stall I started to turn it counter clockwise. I noticed the eninge started to hold on a little longer. I kept going a little farther and "WA LA", it stayed on. I was so happy. The first time since I have bought the thing, it has stayed on all by it self. So I adjusted the Idle air screw and what not, got it running pretty nice, and just sat back and enjoyed the beautiful sounds.
I turned off the engine, finished up a few things before it got to dark. Then went in to get the wife to show her the good news. Came back out to start it up and no go! 
It turned and turned and turned, didn't even start this time. So she was like way to go, at least it was running before. So I go back to the engine, and noticed the choke was all the way close. The cam had turned so far that the throtle had been stuck open almost full. So I held the cam back to warmed up position and had her turn it over. Started right up. It idled a bit rough at first, then once warmed up ran fine again.
What is the deal??? It either runs fine when warmed up or starts fine, but not both. If I turn the choke back so that it can start when cold, then it won't stay on. Do you think the choke has seen to many miles and needs to be replaced? When I had it adjusted so that it would stay on, the notch was pointed about 7 o'clock, or about 1/4 turn past the 3 little bumps. I know it shouldn't be that far off, but it ran, so I was happy.
What should I do? |

Try pushing on your gas pedal before you try to start it after running it. You need to reset the trottle cam & when you depress you gas pedal it will reset, well , it should  I adjust my electric chokes by loosing the 3 screws & turn the choke until the butterfly flap is just about closed all the way & tighten the 3 screws back up. good luck
**EDIT** the carb/motor needs to be cold when setting the choke****
