I have a Baja mb200 that's been fairly well maintained with a gtc torque converter conversion. other than that it is completely stock. I was working on it a few days ago, just tinkering, and a screw had fallen down underneath what I think is the governor rod. in the process of retrieving it with my giant fingers I believe I may have messed up the governor because it idles at a much higher rpm than before. I tried adjusting the small screw that affects the governor but now it runs for a few seconds and then dies. Any suggestions?
