Is it my imagination or does the black cam in the middle of the pump move very little when you twist the throttle ?? My pump timing was not very far off at stock. It seems that if you attempt to adjust the timing too far, it won't spray gas at all. As soon as I moved the pump timing screw from the position where it gave me no gas, to just after it gives me a full squirt, it was just clearing the slide where it should be. Anyway, when your checking the during of the squirt, do you wick the throttle fast or do you slowly twist through to full throttle ?? To me it seems like the duration of the squirt is shorter (faster) when you wick the throttle, as opposed to a nice even twist. ------------------ Matt W 00 YZ426F 94 YZ 250 http://www.mattwilliard.com "Don't worry about me, how's my bike ?"
