Husky 555 running poorly

[redhawk23]

Hi,

My saw pulses at high speed and has cut out a couple times. I tried resetting the auto tune by running down a log for 5 minutes. It didn’t cut out but it didn’t stop its pulsing either. The fuel filter is new and the air filter is clean.

Any ideas?

Thanks
