Carb Issues
 
Well I have had this issue with my Carb for some time and just drove around it. But I got a bet going with a friend that im gonna be settling at the track nov 5. So if I go from idle to half throttle or more I get fire out the Carb. And it happens while driving from any speed to wot. But if I stall out a 2k then wot no pop and the car screams smokes and goes. It just seems like I have to roll into it till the elms get up there and then I can coven the secondaries.

Just curious, what's your timing set at? Also what kind of carb?

Floats
 
Have checked your float levels or even if the floats are working correctly. Some carbs have a sight glass while others, you must remove a screw on the side. Sounds almost like too much fuel dumping in when you press on the gas up to stall.

I used to belong to a forum for another car, and the resident carb guru had a saying: "90 percent of carb problems are timing problems." I had what I thought was a fuel problem. I went as far as swapping carbs, but it turned out to be an ignition problem after all. Just a thought.....
