I have a CLONE HiPo Autolite 4100 for a 4 speed car. You can see pictures here:

I had this carb restored by KP carbs over the winter and got around to installing it earlier this month. I sent it back to him as there was no adjustment in the A/F mixture screws and Kurt found some debri in the primary booster above the idle circuit, which he repaired, road tested on a car and shipped back to me. I installed it last week, and I couldn't get it to idle correctly. It ran OK past idle, but doesn't want to come off high-idle speed without manual manipulation of the idle arm. I'm not a mechanic and I don't know how to work on these things. I took it to my mechanic and he couldn't figure out the idle problem without taking it apart. Kurt swears up and down that it works perfectly and tested it on a car to determine such. That's all I know about this carb. It's still on my car, but it's coming off if I can sell it quickly. If I knew how to adjust carbs I would tinker with it, but my mechanic is over $100/hour...
Asking $575 plus shipping sold as-is
Here's a pic I took yesterday
