I’ve noticed that my throttle doesn’t always fully close when I lift slowly off the pedal. After slowly removing each section and rods I am back to the pump lever. When I lift off fully it closes all the way. However, if I do it slowly it doesn’t. It seems to stick a slight bit near the end. When I move the lever on the pump the same thing happens. I’ve sprayed some penetrating oil behind the lever connected to the pump but not much changed. Any ideas besides putting another return spring on the connecting rod?
