I am trying to get my motor running right. I don't know where the air adjustment screw should be set on this motor. Model C25ELRS 25hp Yamaha<br /><br />Any help appreciated.
I have recently acquired a 1994 Sylvan Classic 14ft fishing boat with a 1994 Yamaha 25hp outboard motor(model C25ERLS). The motor had a new fuel pump and carb rebuild kit put on it when I purchased it. The motor runs great but not for very long after it's initial start. It won't run higher...
