My new engine isn't running to well. It did for a couple weeks but is going downhill. Hesitates really bad taking off from stop lights or just cruising around 2000 to 2500 rpm. Eddy carb (1405), Eddy air gap dominator, small chamber heads, 194 intake, big rv cam, 8 1/2 to 1 dished, accel everything. I am leaning toward the trouble being the carb, any suggestions? It's getting to where it's almost not running.
