how often should the spark plugs be changed?
i had a little insident last night and after some serious backfiring i think it's time to change the plugs.
What type of spark plug do i need for a set of twisted wedge aluminum heads?
whats the ideal gap?

Thanks a lot.

a little but nothing super significant...just up the timing a little and you'll be fine
