Ok, when i originally disconnected the rectifier, I had a 2-fold problem, i was that is was boggy like limp mode, the second was that it would just shut off suddenly. When i disconnected the rectifier, it would still shut off. Now I disconnected the rectifier, and it ran great, for a good 10 minutes, very responsive and crisp! I will order a new rectifier first thing tomorrow. i think i have it.....with all your help. thank you! BTW, when i was re-building the carbs and changing the lines, i found the battery cables to be very loose, which must have been my shutting off issue!
