I converted my Carter AFB carb from hot stove to electric choke. I connected the hot stove pipes to the choke housing so the vacuum is pulling on the choke piston and it seems the choke doesn't close when I first start up in morning, I have to get out and help it close because it seems to be hanging up when the electric choke fully opens the day before and the car starts up. Without the choke the car starts up harder than with it. Is there something I am missing why this is hanging on fully open?
