Using the choke? Choke actually working?

Prime the fuel bulb?

How many pull does it typically take?

Yes using choke,,it is working and closing fully..using the priming bulb until it goes solid. I can hear the fuel moving when priming. 10 pulls and sometimes not even then. If I remove cover and give squirt of easy start off it goes straight away?
