Kohler engine in an old Bobcat skid

Hi everyone, I am new to this site. I recently bought a 78 bobcat skid with what I believe is a 25 hp kohler engine. It had a broken Governor( snap off, or blown apart). I installed a new one and the same thing happened after about an hour of use. Is there any thing else I should be looking for that would cause this? Thank you.
