I would deffinitey look that up. it also could be your secondary jets are clogged, how long has it been since the jets were taken out and cleaned?

could have been a poorly done mech secondary mod, check the linkages for broken tack weld or wire tie.

check the mech secondaries link in the FAQ, that shows the wire tie method for basic pointers

Along with everything posted above - If you have vacuum secondaries, the diaphragm could be shot. Also could be a clogged fuel filter.
