***THE NEW PROBLEM*****
I get a 2500rpm flutter or flat spot or something...i dont know what it is...like a flubflubflub...not crisp. I can gear down to get over 3400rpm and it goes away. I just RE-sync'ed the carbs last night...I didnt run it, it got to late.
Just got home and decided to the "SHOT GUN" method. If the flutter is still there, what would be my next step?

Well i finished the SHOT GUN. RE-synced again. Fix the wire crimp issue. Added distilled water to the battery. The flat spot went away. NO THANX TO EVERYONE IN THIS FORUM. 20 views and no replies. Thats just sad. Here i thought this was a big family in this forum and you just let the fat kid suffer.
Now that I got that off of my chest. Maybe someone will help me on the next question. When I sync the carbs, what order do i sync them in? 1 & 2, 3 & 4? or is 1 the reference carb and you sync 1& 2, 1 & 3, 1 & 4. any help would so kind. Thank You.
Thank you
