I have a 26" troy bilt I bought brand new last year. I go to start it tonight and hear this loud noise as I am turning the choke to run. The noise sounded like a pistol being fired. The auger works. But the drive control (basically my accelerator) isn't working which makes it near impossible to use since it is a heavy machine to be pushing around.

Put it up on its bucket and take the bottom cover off and check the drive system be it chain or disc drive. Make sure you drain the gas before you do this.

With the sound I would guess a tension spring let go. You will need to pull the covers and check

I have a 26" Troy Built that was given to me. It is about 3 years old. While looking it over I noticed the drive belt looks the be about 1/4" wide! It is definitely too small to be a 3/8" or 1/2" belt.
