				| 
 |  
				| In priming and starting the engine it is useful to know where the fuel 
goes from these two sources. Pumping the throttle causes the accelerator
 pump to squirt fuel into the throat of the carb. This fuel usually runs
 back down and into the airbox causing the potential for a fire there if
 the fuel ignites. That is why you should keep cranking the engine during
 an induction system fire.
 
 The fuel from the primer goes into the supercharger housing. Raw fuel
 from here will run down into the intake risers for the lower cylinders.
 There is a potential for hydraulic lock if you prime too much (put too
 much fuel in there).
 
 Know your systems.
