Question for you small engine experts, I've had this gas leaf blower for probably 5-6 years and its always been a pain to start. Same brand weed eater starts on 2-3 pulls. This blower takes 7-10 on average. The problem I'm noticing now is that if you use it and turn it off, and try to use it again shortly there after you will pull on this thing 30-40 times before it starts. Sometimes it wont start at all unless you wait a few hours. I put new plug and air filter in back in spring and I keep sta-bil in the gas for it. Any ideas on what I can do to fix that?
