Thank you - that's what makes carbs frustrating (when it's not working) and oh-so rewarding (when it actually runs).

Thank you very much guys. Sounds like I need to get a 'new' engine.
Can I put a newer engine in the frame, like a Seca II engine?
Thank you. I will do both because this is my first bike and I have some sentimental value attached to that.
