Many have commented about a loud whirring/squealing noise coming from the starter immediately after startup. It happens as soon as the engine starts and you release the starter button. The cause is a dirty starter shaft keeping the starter gear from properly retracting after startup. The solution is to clean and lube it.

Here's how:

Thanks for your time and effort in putting this together. I haven't ecountered this problem yet, but it doesn't appear to be a daunting task.
If/when I do have to tackle this problem, I will have your reference with me.

Thanks again!

Mine sounds fine, but I think I'll do this while I have things apart for my spline lube this winter. Thanks Steve!

I can not seem to access the starter service PDF. Is anyone else having this problem.

Awesome job, Steve!

Thanks! Uh and I can't thank you enough for coming up with something to give Jamie another project!

Nice work Steve!
I decided to sell mine instead of fixing it

Thanks for the info, I printed it off and placed it in my book of cool repair procedures.
Thanks again...
