Mower wont start only whines

Please help. I just got a 1986 wheelhorse off of craigslist. It worked fine the first day then today it stopped running. Now when i turn the key it just makes a whining noise. It will not turn over. And i know the battery is new. What could it be?

It is a brigs and straton engine

Can you turn the engine by hand? If so you may have a bad electrical connection, possible starter failure, or the new battery may have a bad cell and not working properly. If you are not getting at least 9 volts to the starter it won't work.

I took a look at the starter and i looks as if it ia trying to turn the mtor. But the motor wont turn. An i cannot turn it by hand either.

Have you checked the starter teath on the pinion it could have stripped the teeth on the top of the motor

I'm with drummer boy,look at the gear on the starter and the ring gear on the flywheel.a lot of these are made of plastic and the teeth either wear or break. russ

I'd go with a bad starter gear since it whines.

Starter can be bad, but before changing that check to make sure the battery connections are on the correct post that could also be a prob; and an easy one at that. that would be much better than replacing a starter motor. if it looks in good condition you can rebuild a starter sometimes cheaper than a new one, if you wish to do that. Prob find parts at local shop or online; cheers

Starter Motor on my Husqvana failed to start engine. I replaced it and the Ignition switch. Battery is excellent and the power flows but the starter just whirrs. Is there a chance that the second sprocket they sent me with the starter a different size and might work better?
