engine has 4 carbs no cokes - 2 carbs have enrichment injectors (prime starters) -- the prime starters
when running have a steady 13.17 volts - should they pulesate - or what could my problem be for my
hard cold start - have a spare set carbs and primers, changed it as a set - same thing. stan
 
The two primers are two needles that when cold are open -- they are wax seated so as the engine warms up
the two needles close, this gives you a richer fuel for start up
