I had my engine rebuilt 600 miles ago and I noticed it doesn't run well at low rpm's. I searched and saw the thread on vacuum advance possibly affecting this so I just checked and there is no hose running to my distributer. I know that before it was rebuilt it was hooked up. I searched around for somewhere to hook it up again and don't see where it could go. I have a Genisis FE iron block , Edelbrock Performer intake, Mallory Unilite distributer and a Holley 850 double pumper. There is a hose coming off the back of the carb going into the right valve cover with a PCV. Any help will be greatly appreciated. Thanks in advance. Chas
