Idle Mixture Screw - Broken Tip RemovalSeveral XSives have encountered the broken idle mixture screw syndrome when overhauling carburetors. The tips break off easily in the metering hole when overtightened by overzealous "mechanics". After breaking off, the tip usually remains tightly pressed in place. Removal is essential. The problem is finding a way to apply adequate pressure on the broken tip from inside the carb throat. The "Push Pin Trick" and "Pick Trick" techniques make this possible.
This method uses a push pin and box wrench to push out the broken tip of the idle mixture screw.
