Biohazard
Pulling the carb and cleaning it is def my next step.
When I first tried cranking the motor a while back, you may recall me saying how some gunk formed at the bottom of the bowls and that the floats had gotten stuck in it causing her to flood. I'm going to have to assume, for now, that I've got more gunk elsewhere as well.
My floats were adjusted too low, corrected that, but it's still not happy.
