What do you all do for this?? I guess you're supposed to blow near the fuel line entrance on the exhaust but that seems kinda weird, any better/easier ways??

Several easier ways...You could plug the exhaust stinger and turn the engine over until you see fuel get to the carb. You could install a tank w/primer button on it.(I don't recommend it, air leak) You could disconnect the fuel pressure line at the pipe, and blow into that until you see the fuel get to the carb. You could plug the stinger and pop the lid to the fuel tank a couple of dozen times.(but if dirt has collected around the lip, then you run the risk of dropping it into the fuel tank)
I use a starter box, and it is super easy for me to plug the stinger and spin the engine, but any of these methods will work.

Yup. The simplest and safest is just plug the exhaust and crank the engine a couple of times whether it be a pullstart, electric, starterbox, whatever.
