Hi Kate, the way to bleed any air out of the system is to run the engine at a high idle speed for a couple of minutes then let it return to normal idle speed if its still a bit lumpy at idle repeat the high idle again this will remove any air, if it is reluctant to start only use the starter for10 seconds on then rest for 5 seconds until it starts so as not to strain the starter and totaly flatten the battery
