went to go start the Rover (Buick 225) this afternoon and after several cranks I got ignition, but then it stalled out and the carb was overflowing with gas... The engine was all but trouble free till today... bad case of flooding? How long until I should be able to start it? Side question but related... would a non vented gas tank add to the problem? I replaced the seal on the gas cap and now I’m certain I have a fairly closed system..
