OK I got the old cinch pin out and the new one in, curved side facing out. And tightened it as hard as I could. It is tight but the carb still has some give in it and it still shifts about 1/16th of an inch when moved by hand. Is that a significant amount to matter? If I leave it like that will it eventually loosen up again to the point will the pin will have to be replaced again? Is there something I can put around the carburetor to make it even more tight such as epoxy weld http://jbweld.net/products/jbweld.php ?
