I have a Toro Timecutter MX5060, Kawasaki FR691V 23hp engine. When I start it after its set up awhile, say a week or so or longer, the starter makes a howling sound. It never fails to engage or start up but I'm thinking maybe a bearing or something is bad. Its been doing this for several seasons so its nothing new. I've just never bothered with it since it does start up. If I stop mowing for a water break, then go back to mowing it doesn't make the howl. I'm not a small engine mechanic but I can do some things; I'm wondering if I can take the starter off and see if I can see why the noise is there, buy parts and fix, or just ignore it, or just get a new starter. I've seen some on Amazon for about $40 but they all are made in China.
