Where do you buy resistors as a stand-alone product? I don't
think I've ever seen them...only new plugs?

Today, with the help of Ed Martin we timed the newly IRAN'd mags to 22 degrees BTDC and then tested everything by hand to make sure we had sparks and in the right order.  we rotated all by hand for a while just to make sure everything went well and because I had that previous Niagara adapter problem.  I then had an idea to review a past LML note about resistors in Champion spark plugs.  The top plugs were removed so I decided to check them for fun.
