Thanks for letting us know our comments were down! We worked out the glitch and we are back.
Let us know the make, model and year of the car that you are installing the 6019 DP on and we can help you out.
I purchased the DP6019 recently and have a bad stumble off idle and I can’t figure it out. I’m using Hedman Hedders and the Holley 8007, stock distributor. There is plenty of rev up in the garage, but when I take it for a ride, it falls on it’s face just after idle. It picks up speed in about 5 seconds with a lot of oomph, so I know the potential is there. The engine is fine, and was running perfectly before I made the change. I have tried different vacuum ports, different accelerator nozzles, and even different springs in the distributor. I also replaced the vacuum advance to be sure that was working. What can you tell me to help me with this?
