Kohler Courage V Twin Knocking Sound When Cranking

I hear a knocking sound when cranking it over but it goes away when it fires up. Also it struggles to restart like it has a weak battery but battery has 12+ volts and still does it with my jump pack on it.

Here is a short video. https://youtube.com/shorts/Cyl40VJZWbI?feature=share

I just swapped starter out and it went away and starts a lot better. Whew.

make sure that all the battery cables are clean and tight. Also clean the negative ground cable where it connects to the frame. May want to check and/or adjust the valves. Also the Courage twins are notorious for having starter issues. Top starter bushing wear, and bending and breaking starter shafts are not unheard of.

It was the starter.

Might want to check the engine mounting bolts just to be on the safe side.

And those starters aren't cheap.

Not sure what kind of knocking sound it was. But may have been a loose magnet inside the starter.

The ones that I always liked with the Command solenoid shift starters. The replacement starter solenoid was $171 and the complete starter with the new solenoid was $189.

I've bought a few from Stens. And theirs seem to hold up pretty good. Better than the two I bought from Amazon.

You know to really cure the starter problems on the Courage V Twin put a starter for the Command V Twin on it. You will have to do a little rewire on the starter but it is not hard to do. And in the long run much better and does not cost that much more.

If you had a loose magnet it would not turn the engine over

Forgive my noob question but are you able to start it manually and how hard would it be to do this? Can you start it with a drill? Is it possible to recoil start? Or are these motors too big?

I have a 23hp Kohler and wondered if I could still start it if the starter/battery ever died?

I think you probably could. I've done it on the bench before on a Briggs, with a big drill. But that was before I was warned about overtightening the bolt that holds the flywheel.

I doubt it since the Kohlers have no compression release.

I suppose that the reason for their bigger starters.

That would be it.
