NEWB here. I have a Grubee 66cc Skyhawk. For some reason, the bike only starts when the clutch is engaged and I start it normally by riding it and popping the clutch (even then, it only putts a few times and dies, but one problem at a time) I installed a pullstart and to start it, I first opened to gas valve, locked the clutch to disengage, then gave it a bunch of tugs. Nothing. I made sure the spark plug is making a spark. ALso, I disconected the kill switch and made sure the wires are not touching the frame. I am at a loss. Why would it not start with the clutch disengaged? Any help would be appreciated.
