Alright so I bought my son a late 90's PW50, tore everything apart, cleaned inspected and reinstalled including the carb. It takes forever to get it to fire, but if I stand it up on its rear wheel for like 5 seconds then set it back down and kick it fires. It runs perfect after it's warmed up. Yes the switch is in start, fuel petcock is on, what am aI looking at here? Still clogged jets? I don't have a compression checker but I was thinking about just rebuilding the top end. Any thoughts?
