I don't, it seem like there to much air in the gas line, and I've tried everything to get it all out, is there any tricks??

The bystarter enriches / adds fuel when cold starting.... if you run fine once started as stated, then it is a broken bystarter ... which is broken in the out position, thus not allowing enrichment during cold starting. It is also called auto choke. You can test it many ways.

Use the wikispreed, the service manual, and youtube to learn how to do the simple test.
