Paul, my way:
- full choke by left hand
- open trottle by right, keep it open
- start (it fires immidiately)
- right after it fires, choke off fully or partially, while still keeping trottle open, keeping full choke makes mix too rich im my case and engine tends to die
- keep trottle open till engine is not warm enough to keep idle or use idle knob and screw it in to increase idle rpms.
