I bought a 1994 Yamaha Riva Razz, and the next day, I am already having problems with the throttle. I was driving it and all of a sudden, the throttle sticks at about 3/4 down. It is kind of a safety issue because when i start it its already moving. Also, It doesnt seem to run as smooth, and I have to keep it half choked or it will sputter a little. If anyone has any advice id really appreciate it. Or if you know of someone who works on these in the Lansing MI area that would help too.
