I don't know how to check the color of the spark. As noted previously, fuel just barely trickles out the windows. Placing my hand over the secondaries bogged the engine when I had the square slots, that was before I closed the secondaries. Now it doesn't bog when I cover the secondaries.

If I turn the mix screws in on one side only, it gets very rough and almost dies. If I turn both screws in, it will die. My buddy has an Edelbrock 500cfm carb that I can try to see if it works.

Any thoughts on why it runs well when warm but then gets rough when it is hot (after 15 minutes of driving)?
