Stihl makes 2 versions of a few saws, 1 with the EZ start and primer bulb as well as an EZ chain tightener and 1 without. I just bought a new Stihl Farmboss and chose to NOT get the EZ start, primer bulb and chain tightener. The EZ start one had more plastic and felt cheap especially with the big plastic knob for tightening the chain.
Choke on..1 pull…choke off and pull to start.
