Pull the fuel line and coil wire. Crank it into an empty water bottle to check for water or particulate matter. I had a new Edelbrock with debris in it.
I will try doing that tomorrow. But I had some gas line antifreeze handy so I put some of that in the tank, and took it down the road, It seemed like it was alot happier, at idle it seemed like it had a random popping out of the exhaust, not loud or anything, and It didn't do that when It was colder when I started it.
