I have a 1990 suzuki dt15c Serial # 01502131904 that is running rich. Since it is oil injected, it is not recommended to adjust the injector. I cannot seem to locate a mixture screw on the carburator. The plugs are oil/gas soaked after every use. I do troll alot but try to rev up the motor frequently to keep it from loading up. The motor starts quickly and runs great until the plugs start to foul.<br /><br />Is there any way to lean out the carburator without tearing it apart?
