Holley/Demon Carb stumble

Had some honey does today but got out there and pulled the bowls/metering blocks and attacked then with carb spray. blew a tiny black piece of crap out of the pump housing on the front bowl.
Didn't jet it as i wanted to see what would happen. In neutral it is better, out on the road..... stumble is still there but improved a little.(could have been just because it was heat soaked. If i don't get called into work tomorrow, i'm going to jet it up and see what happens.
