Fixed bb went in the diaphram, seen hole in diaphram housing(?)where it seats, put back together and no more leaks and runs great. When I first started it great power but gas was leaking from the carb somewhere,so just took apart blew carb cleaner through the passages. now I need to find accessories which has been a problem so far for this Mcculoch MT725 weed whacker.

Nope still leaks gas somewhere stunk up the shed got to get a carburetor rebuild kit and see how she does, can't find no attachments for it either Riobi has blade/edger attachments i hear will work on the Mcculloch MT725 have to order one and check it out, got to find the line shield also.
