Hi, the symptoms you described is most often caused from miss-adjusted valves. Your engine has a compression release to allow the engine to turn over easier during starting and as soon as it starts the compression release disengages and normal compression resumes. This is common on overhead valve engines as the valves need to be adjusted after the first 100 hours and then every 200 hours thereafter. If you are not familiar with performing the adjustment, bring it to your local small engine repair shop and they will perform the job for you.

I normally charge 1/2 hour labor for the job. It is possible that your starter is getting tired but have the valves adjusted first before spending money on a starter you likely do not need and will not solve your problem. I hope this is helpful and happy mowing.
