MK111 pulse time too long

Kits Timers and Clocks
1

I want to use this timer kit in my aplication but only problem is that pulse time is too long. Is it possible to decrease pulse time? with which component should I experiment.
I already find out that I can change pause time with increasing C3, is there any similar solution also for pulse??

Try bridging R1.
Keep in mind that pulse cannot be made too small or relay will stop functioning.
