Quick Question ...

Finally decided to go out and figure out why the 72 has started backfiring so bad. Spent all day yesterday tinkering with timing, carb adjustments etc ... and it still runs no better. I'm heading out in a few to buy new plugs and a distributor cap. I noticed a red powder inside the cap yesterday, any idea what it is and why it is there? Thanks for any advise. :steering: I just want to cruise in it today
