My "pull start" motor has been giving me trouble. I usually have only had to pull it maybe 4 times for it to get started. Lately it's progressively getting worse. About a month ago, I started having to pull it like 9 or 10 times for it to start. Two weeks ago it was like 15. And this past weekend I had to pull it about 25 times for it to start. Through out the day it isn't bad. It starts right up. It's just that initial start that I'm having trouble with. What is my problem? Please help....<br /><br />Rick
