318 wont start and backfires out the carb?

have you set the reluctor gap in the distributor? .007"....

Could you explain this process to me? Unsure what this is or how to do it?

Any way to check my MSD box with out sending in?

Heading out to get a new cap and rotor now, well see if that solves my issue..

Thanks again.
