It just started a few days ago, when you start it up it idles perfect but as soon as you give it throttle it starts popping and cracking like its flooding out...I thought it was the carb. boot bc it had a hole on both sides of it. Replaced it nd it still does no better. Checked spark plug, valve clearance, air cleaner nd made sure no water in fuel. It sounds like a vacume leak or water in the fuel. Or like the timing is retard. I only have a maintenance manual. I would b much abliged if someone could give me an idea? THANK YOU!
