you dont need to do anything with pulling the clutch cover... WOW, your gunna screw this dude up telling him that. Bro this is what u wana do, pop open the pump cover, disconnect both hoses where the connect from the pump, in other words take all the hoses competely off the pump, then unscrew the pump, its like 3 little screws, open it - easy stuff and take the plastic gear out, put back together, put pump back in, throw case back on, get some silicone, silicone the two holes commming from the pump cover and silicone the little hole on the carb where the oil line connected.
