Hey guys, I'm new to the bicycle engine arena but I've been learning a lot over the past several weeks. I ended up getting a pullstart so I don't have to break my legs on pedal starting. I've got everything adjusted but two things. As engage the clutch when I try to give it throttle, it wants to almost move but it just sits there and if I let completely off the throttle it dies instead of idling. However, when the clutch is engaged it rolls as if the clutch is disengaged. I got a 69cc China girl (silver slant). I'm thinking I should tighten the clutch plate but don't want to risk anything messing up. Any help is appreciated.
