    Blackmax reeds.

    some good, a coupla of 'em not so good... back fire is usually one of two things.. timing and/or wiring (switch box/coil wiring usually)..... this could go back to how you "fixed" tha cut off trigger wires.. best ta bite tha bullet and geta new (used will probably work, they hardly ever go bad)...
