hey, I got my blaster yesterday and I wanted to switch over to mixing my own gas by doing the oil pump block off. I took off the oil tank and the side where the pump is. I then took off the oil pump but there is no plastic gear? I read a few of the diy guides on this but it sounded like there should be a plastic gear attached to the outside of the pump. Or do I have it completely wrong and I have to take the pump apart? There looks to be a little gear inside the pump but it appears to be metal? and does anyone have any pictures of the pump apart just for refrence?
Thanks
