Bought this today, says Powerking in the booklet, sales guy says 66/80cc I paid less for this motor than a 49cc from where I got my first motor which is also a 66/80.
I bought my 2nd, 3rd and 4th (out of 6) engines from Powerking. Had absolutely no problem from any of them. All were 66cc. When buying the 5th he didn't have any at the time. 6th was from a member. First from luckyearlybird/BGF----> never again
