if not the starter could be that electric start your have!!! i have seen nothing but trouble with those in my shop, always locking doors, or having to hit some kind of switch to start it when in the car........i know in my lawn mower however, that every once in awhile i would have to wd 40 the sprocket for the starter because it would stick and not want to spin out and catch the other gear...but it does more then anything sound like the starter
