He still needs to check his jet for blockages, and check that he's getting enough air to his engine. There is always air in my line, no matter what I do, so I know that this is normal. When my engine didn't start after my head came loose, (I torqued it down and still didn't start, even though it really REALLY wanted to) I checked my flow through the line, and that was all good. I checked my jet, and there was a piece of dirt lodged in there. I blew it out, and my engine runs now.
