Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you.
Rick is not online today. Can you explain your problem to me?
There are three possible reasons for our problem. Valves being out of adjustment, faulty decompression mechanism on your cam gear, or a bad starter. The most common of the three are valves being out of adjustment, something related to your valves.
Remove your spark plug, to see if your engine will spin freely, as you attempt to crank it. If so, then checking your valves will be the next step in troubleshooting our problem.
Remove your valve cover, and check all parts associated with your valves. Make sure both valves are opening and closing properly. If so, check your valve clearances.
Thanks for this information. I believe your engine is a V-Twin Kohler Command engine. Your engine have hydraulic lifters, so you will not need to check valve clearances on this particular engine.
Check instead, to make sure your valves are fully opening and closing, and is not partially sticking. Sometimes, if one of your rocker arms are excessively loose, when your piston is at top dead center, on your compression stroke, this could be an indication of a problem with that particular valve. Also, check for bent or broken push rods.
We can continue from here.
Thank you for checking this for me. Based upon your results, I would remove the starter, and get it tested. Your starter could be worn internally. Worn brushes, cracked magnets, bad armature, etc. If you have a local alternator / generator / starter shop, in your area, they will be able to correctly test your starter. It is best to be sure, before purchasing a new starter.
You are very welcome!
