LOL, not meaning to be a smart A** but if you close your eyes you might trip on one of those engines they're so plentiful  <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: --> 
 Forklifts, some Massey windrowers (44) and 35 MH combine small Massey Harris tractors ect.
No worries, you'll find one. Great little engines!
