hello i was wondering if anyone could tell me a little about this bike i have recently purchased it and had to replace the points os know it starts but it is wide open and goes straight to the red line. i have gone from salvage yard to salvage yard and the all seem to not have a "butterfly" if any of you can tell me what is wrong or any suggestions i would be verry gratefull.That is about my only problems thanks for reading and hope you have suggestions.
