How do you verify if the oil pump is working correctly on a 90 ? I pulled the cover, verified inlet and outlet, pulled the tiny arse hose to the carb and turned the motor a half dozen times. I had the throttle pressed to feel max oil but nothing comes out of the tube..

Am I doing something wrong or is the pump shot, blockage somewhere, etc ??

If I just drain the oil, plug the carb oil inlet and premix 40:1 is that all I would have to be done to premix/eliminate the pump ?? I was searching and a few threads mentioned rejetting the carb but those were bigger machines being discussed.

Thanks..Steve
