Hey all, I screwed up. I was halfway through coastering my reed valves on the cylinder when one of the bolts holding the valve on snapped at the head. I wasn't even going hard on it, maybe 15 pounds of force. All the other bolts came out bent so I'm thinking they just got weak after 30 years of sitting. Anyways, I tried vice grips but they just ate away at the metal. Before we go through the hassle of towing and welding a nut to it, does anyone have any ideas on how to get it out? Is a cover on the reed valve necessary?
