Hot Start Problem

1986 930, all smog and cat removed, O2 disconnected and CO is approx 2.5%, otherwise stock. I have checked cold and warm control pressures and they are within spec. I have also checked system pressure, and also within spec (min of 1.6 bar after 10min, 1.4 bar after 20min) I have approx 2.0 bar after 10min, and 1.8 bar after 20min. I would assume that the above test rule out the WUR, Fuel pump check valve, and Fuel accumulator. What else could I check?

1986 930
Gone:71,2,4 914's, 70T, 71T(RS),77S
