Just installed a new Weber DGEV conversion kit with a Carter P4070 electric fuel pump. I removed all the vacuum hoses except the Vacuum advance. There is a noticeable improvement in driveability but it diesels when I try to turn it off. I've plugged all the vacuum fittings and removed the vacuum device box on the driver's side fender well. Any ideas? I'll try to get pictures posted soon so you can see the fuel pump block-off and throttle cable adapter I made. Thanks in advance and sorry if this question has been answered elsewhere. I did a search, but didn't come up with anything.
