If what you mean by not priming is the red primer button not priming, replace it. They are easy to find from a mower shop and hopefully doesn't costs alot. If what you mean is it doesn't primes itself after starting, replace the diaphragm pump located at the bottom of the carby and at the top of the fuel tank
