Remove the spark plug and see if engine spins, and watch for any evidence of fluid in the cylinder. What is the engine model number? Example(###) ###-####B1

Is battery voltage at least 13 volts? And cables clean, the starter may just not be able to turn the engine full circle. Can be from too much compression, as engine has compression release , to aid in start.

21R707-0017-B1. Single cylinder Intek, OHV engine. Does engine spin easily with spark plug removed?

But first, test battery voltage when you try to start, has to stay above 8 volts.

Would you have a compression gage available to check the compression? If compression is above 100 psi, the compression release is not working! Release is part of the camshaft and if it is broken, the camshaft has to be replaced!
