I decided to pull out this Victa Corvette that I have never mowed the lawn with since I got it three years ago. Apart from a slightly noisy exhaust, it makes this noticeable squeaky noise as it runs. So noticeable I put on a pair of ear muffs as it got annoying. I have two other full crank 160s that do the same thing but not as pronounced as this.
Does anyone know what it indicates?
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
