FWIW, my was working great, she’ll off at slow and high speed chuff. Once it sat and the shell was on it was 1 chuff maybe 2 revolutions. I’m going to pull the shell again, probably next weekend , and check for the cold solder joints and maybe a loose wire. My tach spacing is pretty tight. I adjusted and confirmed yesterday when it was working before the shell went on.
I’m confident I’ll get it figured out. I just have little to no time during the week. Besides I hear customer service is pretty good with the product.
