    '92 40HP outboard starting issues

    I have a '92 40hp 2stroke outboard motor that I am having trouble getting to start relialby. I figured that it was a gas issue since I just had the switch box replaced and the carbs rebuilt a week ago, so I know that the ignition system is working. Regardless, I noticed gas dripping at the fuel...
