I have taken some pictures of ... lots of things.

The next thing I want to tackle is rough the idle, specifically at cold. Below is a picture choke thermostat, and it looks pretty bent. I am not sure that the choke is operating correctly.

Your choke isn't working right. The choke thermostat arm is supposed to be straight. The cold rough idle could be caused by the choke not closing all the way because the choke thermostat rod is not straight.

Do you think this would be a good opportunity to swap with an electric choke? Also, in the picture you can see a white wire that is connected to the thermostat, but I does not go anywhere, any ideas of what that is?

Maybe I should start a new thread about this.

It is always a good time to switch to the electric choke thermostat.

The white wire is for an electrically assisted choke thermostat. Your 73 probably didn't have one stock. Someone probably swapped in a thermostat from a later year.

Wow! Thanks Reed!

I have contacted carbsonly.com about getting the electric choke conversion kit. I'll have to look at the carb and throttle shaft next. I found a sticker on it labeling it as 're-manufactured'. I have seen many comments on this site about the dubious quality of them. Would you recommend a rebuild kit for this? I also think some fuel is seeping out around the fuel bowl gasket as well.

Never hurts to go through a carb and do a good cleaning and adjustment.

A rebuild kit won't fix a worn throttle shaft, though.

Exactly. I had one rebushed a dozen years ago, cost a bit but it made the idle smooth as glass. For the life of me I can't remember the name of the carburetor shop that did it, but it was a mail in operation with quick turnaround. But like most Holley 1920s, it did eventually fall apart internally and I tossed it in the trash. That model carb is easy to disassemble and clean, so I'd go through it to see if it helps any.

Here's the trick I used to determine my throttle shaft was worn out. Step one, once the engine was warmed up and the choke was off, I sprayed ether around where the throttle shaft sticks out on both sides of the carb base. Idle increased for a moment. I shut it off and slobbed grease around the throttle shaft where I'd sprayed. Cranked it up and it idled glass smooth. The grease sealed it up. You can't always tell if the bushing is worn out just by jerking it back and forth. Mine passed that test.

Ok, put the electric choke on yesterday without too much trouble, but I think I will need to do some adjustments on the carb. I looked at the knowledge base post and I think I understand the procedure.

So this brings me back to the carb in general. I am looking for a rebuild kit, and was hoping someone could recommend a good one. Would this also be good time to add a heat shield under the carb? The style recommended in the fuel line mod article.

Also to get back to throttle shaft seeping fuel: I was able to see fuel leak out from the shaft when I jiggled it a bit, so I think it definitely needs to be rebushed. Is it worth it to have it done? Can I do it myself? Should I just take this opportunity to look for a replacement carb before committing to a rebuild + rebushing?

In the forum messages related to rebushing it is suggested not doing it by yourself unless you know what you're doing and you have the tools to do it right. Maybe somebody that has done it himself/herself can chime in.

I have a good quality American-made kit on the shelf for your carb. I'm about to advertise a bunch of carb kits for sale; I'll leave that one off the list if you want to buy it -- send me a PM. I may also have a new float; need to check.

Carburetor operation and repair manuals and links to training movies and carb repair/modification threads are posted here for free download.

As for rebushing: I would not put money beyond a carb kit and float into a "remanufactured" carb such as the one on your car. Not worth throwing much $$ at a carb that will likely never again be all the way right.
