Small Engine Troubleshooting Problems? Ask a Mechanic Now.
HI, my name is***** will be assisting you.
While it could be a starter problem there are a couple other things that you might want to check prior to replacing the starter. Can you tell me if this is a Kohler command or courage engine?
This engine has a mechanical compression release built into the camshaft. If the valve clearances get off to much it will affect the starting of the engine so the first thing that I would check is the valve clearance. You want both valves to be set a .004 inch when the engine is cold. If this is not almost perfect it will cause you problems. If you find that the valves are properly set then I would suggest a possible compression release problem at which point you would end up having to replace the camshaft.
You can adjust the valve clearances very easily. You just need to remove the valve cover from the front of the engine, it is held on with seven bolts which normally take a 10mm wrench. Once you have removed it the rocker arms and adjusting nuts will be right in front of you. The adjusting nuts have a small set screw in the center of the them so in order to turn the adjusting nuts you will need to loosen the set screw. Before I would loosen anything I would check the clearance between the valve stem and the rocker are just in case the clearance is okay. You will most likely have to replace the valve cover gasket as it is made of cork and can rarely be reused. I have included a diagram of the valve area to hopefully help you with doing this.
You will need a feeler gauge that has a .004 inch gauge in order to adjust or check the clearances. If you don't have one you can purchase them at just about any automotive parts store.
Thank you it has been a pleasure to assist you.
