 Greencut gs 7200. The original carb setup was a exact replica of a Redmax g 621, even the venturi size[15,08]. This is small for 60 cc, for 70 cc is smaller. So whats in the pictures is my doing. I drilled a hole in the case for a impulse port, made a new trottle rod [modified from 50 cc Zenoah clone], enlarged a bit the intake  block and filter  holder.The carb is a chinese carb for Husky 365-372.I had to drill a hole for the trottle rod on the right side . I now have fast idle on the choke button.
