I'm doing some more spring readiness checks on the Husqvarna YTH21K42 Lawn Tractor.

In this video I want to check the valve clearance. There is a Kohler Courage 21 HP engine in this tractor and they are prone to have valve cover oil leaks and valve setting issues.

When I check the valves I'm not disappointed with the settings and the engine sure looks to be running good and not burning too rich or lean.

I examine the spark plug and it looks just fine too. Then I do a little chin wagging about cheap off shore plugs versus known brand name plugs and give my thoughts on the topic.

Let me know in the comments if you think I should have adjusted these valves.

Happy Canada Day and also Happy 4th of July too.

Thanks for watching and I hope you enjoy the video. Please 'thumbs up' me and leave me some comments. And if you haven't done so already, please consider 'subscribing' to my channel. It sure helps my videos get noticed and my channel grow.

I hope you all have a great week.

We'll talk to yas ...
