Fuel starvation? 

Check that the air flow sensor is sitting properly (Bentley).

Is enough fuel being delivered? Check that the transfer pump is pumping
and the fuel pump is pumping (I hate dealing with open fuel systems, but
this sounds like a fuel delivery problem, since you have spark and seem
to have okay timing; have you checked to make sure timing is set at 6 BTDC
or thereabouts?)

Is the fuel filter fresh? Could be low system fuel pressure or high
control pressure (problem with warm-up regulator). Check fuel pressures
(something I should do too).
