Hyundai HYBCF31 User Manual page 21

For COLD start move choke lever UP to start position.
N.B. For a WARM/HOT start you will not need to do this.
Place one hand on the machine, and using the other hand pull the recoil until you feel a resistance, then
pull briskly. Repeat until machine starts.
When the engine starts and move the choke to the OFF position. DO NOT let go of the recoil handle
instead allow the recoil cord to return gently. Once started you need to reduce the choke by slowly
moving lever to RUN position if engine falters move choke between START/RUN positions and adjust
until engine runs smoothly.
