Lol ^^^^ I pull a line off my carb and drain my alky out of my fuel tank, pour 93 oct/ benol mix (same as your alky) 20:1, 28:1, 32:1 etc.... Run it until it runs like crap basically, 2 minutes on average, Than I pull my carbs off and dump the purge gas out of the bowls. 5 minutes with everything on average
