Timing problem with PIC18F2620

[Corta]

I starting to work with PIC18F2620 and I simply trying to test output port...

//**************

void main()
{

setup_adc_ports(NO_ANALOGS|VSS_VDD);
setup_adc(ADC_OFF|ADC_TAD_MUL_0);
setup_spi(FALSE);
setup_wdt(WDT_OFF);
setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
setup_timer_3(T3_DISABLED|T3_DIV_BY_1);
setup_comparator(NC_NC_NC_NC);
setup_vref(FALSE);

while(1)
{
output_bit(PIN_A0, 1);
delay_ms(50000);
output_bit(PIN_A0, 0);
delay_ms(50000);
}
}

//**************

#include <18F2620.h>
#device ICD=TRUE
#device adc=8
#fuses NOWDT,WDT128,HS, NOPROTECT, NOIESO, NOBROWNOUT, BORV21, NOPUT, NOCPD, STVREN, DEBUG, NOLVP, NOWRT, NOWRTD, NOEBTR, NOCPB, NOEBTRB, NOWRTC, NOWRTB, FCMEN, XINST, NOPBADEN, LPT1OSC, MCLR
#use delay(clock=20000000)

//**************

I cannot obtain the good delay, I got 2us high and 2us down. I got a 20MHz x-tall. Maybe I've fogot a fuse or something. Anybody can help me on this?
