hey guys, i'm still relatively new to carbs, and i need a hand.

i'm running a barry grant speed demon 650, mechanical secondaries. under very very light acceleration and sometimes just cruising, the carb will surge just enough to annoy the crud out of me. i would presume this would be related to something in the transition circuit, but what?

Surging is usually cause by a lean condition. YOu may also want to know what your timing is doing at that point.
