I ran it a couple days ago. fired it up, ran it for a few seconds, and shut it off to check oil. Fired it back up, and noticed fuel on manifold. Shut motor off, and secondaries kept filling up, faster then butterflies could allow the fuel too drain. So now the carb is off at a buddy of mines shop (ASE mechanic) so he can figure it out. So whenever that comes back is when it runs. Side bar, Holy CHIT! 460+closed building+open 3" manifolds= ears bleeding!!!
