Small Poulan chainsaw with new fuel, new plug, and new carb. Adjusted new carb so it ran very good at idle and top end but it is hard to get running. Has a primer bulb and a choke. Label says to press bulb 6 times for cold start. I've tried no priming to 8 pumps with choke and without choke. I've tried different throttle settings also. It has good compression and spark but just doesn't like to start up. What is the secret to starting these little Poulans. I have a larger and older Poulan that starts fine if I run it about every other day but, let it set three days and it's also a hard starter. I'm thinking these saws are meant to be boat anchors.
