Hope you can help.
I have a bandit stump grinder with a Kohler command pro 27 on it. Backfiring through the exhaust. I can't find any markings on it for horsepwer. This is rental equipment store,so most of the information is off it. The machine is 7 years old.
Is there timing marks, or a way to adjust valves or timing? Could the cam be bad? Kohler tech services said they couldn't help.
Please let me know.
Thank you.
