I'm having starting issues with my MTD riding mower with the single cylinder Briggs and Stratton 14.5 OHV engine. It appears I need to adjust the valves. I have a round metal feeler gauge, but have never done this before. Can someone give me a step-by-step procedure for this task, in very simple terms for an amateur, etc. Thanks.

I have referred people to this you tube video that shows you how to do it. It is not exactly as the manufacturer recommends but it does the job.

YouTube - Lawn Mower Repair Valve Adjustment (http://www.youtube.com/watch?v=NjzX-PUjKmo)

This was perfect!

It's a great video that explains it well and has helped a lot of users here on the forums. Glad it helped you too.
