I have a problem with the bike idling properly. A few people told me it was the low speed jet. I bought a new one and a carb kit as well. I've removed everything from the carb so I can remove it from the bike. However, it still seems to be stuck. Is this common? Is it stuck on the gasket that holds it to the manifold? Thats th eonly place its making contact with anything. How do I get it to rel;ease from teh manifold? I dont want to tear anything up.
