Bridge port question
 

Just a couple of very basic questions.

Do both ports deliver fuel always at the same time?
Or does the fuel follow the path with least resistance (the primary port) first, then start delivering fuel through both the primary and secondary ports when the throttle is fully open?

Also, are there four ports per chamber, opposite each other - two primary and two secondary with bridge, or are there three - one primary with bridge and secondary port on one side, and another single primary port on the opposite side?
