i'm in the habit, as everyone should be, of running the fuel out of my engine when i'm done for the day. as a result, the next day i make it to the track, my motor is difficult to start for the first run without priming it. i got sick of having to take off my airfilter to prime the motor with a few drops of fuel down the carb. since i use a ziptie to secure my filter on the carb while i drive, priming became very annoying. i came up with a much easier way to prime my motor.
I rotate the flywheel until i just start to feel compression. after i fill the tank, i shove my fuel bottle up against the exhaust to make a decent seal. then i open to full throttle & squeeze the bottle a bit, ensuring no gas is squirted from the bottle into the pipe (a downward tilt works if the bottle has fuel in it).
this method pressurizes the tank through the exhaust pressure line & forces fuel through the lines & into the carb. the bottle-exhaust seal isn't perfect, but it is good enough to get fuel flow started. if you don't like using your bottle, anything that can blow pressure into the pipe will work (even your mouth: "he's giving his car mouth to mouth"). the flywheel rotation is important, otherwise the air can pass through the exhaust port & out the carb. i can't think of a more efficient way of priming a motor.
