On my 3310 making sure the transition slots on the primary side aren't exposed too much. Flip the carb over and see how much of the transition slot is showing on the primary side. If it's more than square look at the secondary slots. If the secondaries are covering the transition slot open the blade adjustment enough to square the slot. Then you can lower the idle screw and go from there. Might still need to richen idle screws and possibly increase squirter size. Be sure to adjust the spring on the acc. pump lever and if needed put a diaphram and check valve in the pump.
