Predator500: It sounds like the Hi speed circut is plugged. Make sure all passages are clean. I use carb cleaner with the little red tube and inject into hole that hi speed needle goes in. Then blow out with compressed air. If you put jb weld in the primer fitting on the carb..maybe some got where it is plugging carb up? A good plug is a short piece of fuel line with a rivit pushed in it. Capt,n
