While flying the other day, I lost one of the screws that holds the Carburetor on my .40FP. Looking at the O.S. website, all I found to replace it was the OSMG2135 23390010 Parts Pack 35-40FP. But all I need is the one screw. Is there a parts listing that I am missing. I believe that the screws are 3x5mm, but I am having trouble locating them.

Thanks
