I just bought a 1989 15hp yamaha off of CL out of state where I'm working. The guy started it right up no problems. So I bought it. I got back to the job site where I'm going to store it till I get home and was excited to admire my new toy! I noticed the handle will only turn to half throttle. I took the cover off and can clearly see that it's not moving to full throttle. It seems to be binding somewhere under the flywheel. What could be the problem? :'( I hope that guy didn't pull a fast one on me.
