This is why, when I feel the need to "prime the pump" (figure of 
speech, NOT actually priming the fuel pump but getting the engine to 
actually do something so it will suck fuel from the tank) I do NOT 
just dribble gas from a can into the carbs.


That's asking for an interesting experience.


I always use a can of carb cleaner, squirt a stream left and right 
back and forth to convince the engine to spin up, if only for a 
couple of seconds or so to get the fuel pump working... otherwise you 
could be 5 minutes cranking on it to get a dry pump to finally begin 
picking up gas from the tank.



A backfire from a carb won't leave you with a flaming arm (among 
other things) if you squirt carb cleaner in the carbs, and YES the 
engine WILL run on carb cleaner.   I like the Auto Zone brand... 
works better than what you see at Advance, although Gum-Out works 
well too, albeit more expensive.

PS:   when you do this, NEVER EVER crank with the throttle wide open, 
NEVER.  I mean it. The engine WILL backfire, every single time, and 
if there's any flammables slopped into anything it's gonna 
burn.   Don't do it.   Ever.
