Can't say on the AFB but the Carter WCFB has two holes on the little arm that holds the metal clip that drives the accelerator plunger downward. Perhaps you need to try the other hole (if the AFB has such an arrangement)...just a thought...

Few things:

1. Here's a fancy and expensive cooking hypodermic needle. I'm sure those kitchen stores at the mall have something cheaper.

http://www.williams-sonoma.com/produ...-seafood-tools

Your wife will be impressed that "that stupid car" has broadened your horizons. Now you're going to gourmet cooking stores. Pretty soon it'll be fine wine, art museums, the theater, etc..

2. It is a good practice to soak the leather accelerator pump bellows in oil before installing it. Also a good practice to flare out its skirt. But it'll swell and flare some all by itself after installation because it rests in gasoline. The gas in the bowl also fills the cavity where that bellows is. I prep the bellows as mentioned. But lotsa people don't, and, after a while, it'll work just fine.

3. If you're operating the accelerator lever and not getting gas to squirt into the throat, it's either because there's no gas in the bowl, or the accelerator pump is not working. If you inject some gas into the bowl, and it still doesn't work, then you know it's the pump. It's strange that the fuel pump decided to break at the exact same time you had the carb off for rebuilding. But, hey, stranger things have happened. When you rebuilt the carb, you disconnected the linkage from the accelerator pump. You did hook it back up, didn't you? That "S" shaped jobbie. Remember that?

4. Very dangerous to pour a shot glass as gas down a carb throat. "Priming" like this went out with high button shoes. Don't do this indoors. Don't stand anywhere nearby. Back in the day, we used to chuckle at the motor heads who didn't have eyebrows.

To 62Jeff, I have an initial bog with my AFB (on a '62 ) too. According to the book there is no adj as on the WCFB but you can adjust the stroke of the accelerator pump by bending some of the levers and stops. Once winter goes away I'm going to experiment on mine to try and get the "shot" to start earlier in the pedal movement. Good luck , Bob

Thanks Bob. I've got other issues to resolve such as confirming TDC since my timing tab, and harmonic balancer, may not be properly matched. I'm also going to have someone look at my carb to see if the drag racer I bought it from, "enhanced" it in ways that need to be corrected for a street car.

Once I get past that, if I still have a bog, I'll drag out my trusty ST-12 and see what they say. I think I remember seeing pictures of bending the accelerator pump linkage right at a certain spot to change the pump behavior.

Update(for those who care ...I disconnected the fuel line to the carb and put the end in a jar. Turned her over a couple times and there is gas to/thru the filter. At this point I figured still a carb problem and as a few mentioned, probably the accel pump.

I went ahead for the heck of it and pumped it a few times and saw squirts of gas coming out? I can't explain it, nothing has changed other than disconnecting the fuel line. Is it possible that all along there was gas in the bowls and maybe sitting for a couple days the new accel pump absorbed the gas and started to pump?

Anyway,hooked fuel line back up and no drips, leaks or errors. She started up after a few cranks. So I think I'm good to go and move into the next part of the process and pull the distributor and install Lars recurve kit.

I don't plan to get to this till after the holidays and expect this to take some time with a lot of questions....so here's hoping everyone has a safe and happy holiday!!

thanks for all the pointers so far...

Bob

I bet the leather on your accelerator pump plunger swelled over the last few days after getting wet, and now it finally is fitting in the pump bore properly, thus it now works.

It might have been something as simple as an air bubble in the line, too.

Look at it this way - you've learned some invaluable troubleshooting techniques...

The main thing dealing with fuel problems is "safety first"... take it from a guy who burnt off his mustache and eyebrows in his younger days not being careful....
