Bill M I like your distributor, This type of modification to the old Crab makes it a much better unit than the MSD unit because it still uses a vacuum component for distributo advance under load and cruise. Those that run without vacuum have a rich mixture during cruise witch waste fuel and contributes to cylinder ware, by washing the cylinder walls with excess gas
