The warm-up fuel mixture is dependant on having the correct fuel pressure at the correct engine temp. This is the job of the warm-up regulator! Sounds like the reg. is out of adjustment. To correct the problem the fuel press will have to be readjusted. At 20degC the pressure should be 1.4-1.6bar, & when fully warmed-up the pressure must be 3.4-3.8bar-both pressures w/engine running. The system pressure should be 5.4-5.8bar.
