I know my post got lost because of the database issues, but those that were helping me out I wanted to let you know I found the issue. The issue was the use the ignitor 1 unit. Per pertronix, I talked to a tech, does not use 12v at all. He also suggest not using an ignitor 1 on any marine boat. The dwell on the ignitor 1 does not adjust. This was my issue. Because dwell at a low rpm will open up longer it cause rough idle, but great WOT.

So I order an ignitor 2 and installed it last night. Fired right up and idle awesome. I thought, hey, let me see if I can try and start it without any prime and throttle advancing. Sure enough with the throttle in neutral, just turned the key and vroom. The ignitor 2 adds additional voltage on startup and adjust for dwell at low rpm and is critical for a great idle. Thanks all that help!
