B112 starts right up and idles fine . when I give her the gas she sputters and puffs black smoke .
if I give her gas slowly she works fine .blew out the jet holes( stopped leaking gas after shut off ..bonus ) and changed plug . it made it better , set the carb to specs and then messed around a bunch , can get it to rev up pretty quick if I richen it up but then it idles real high ( lower the idle and it runs really rough )
why is it doing this ?
