Brand new never had oil or gas in it .. 4 stroke not 2 stroke no oil and gas mixing - 35cc - Centrifugal Clutch standard size, should fit with any attachment using same set-up - Chinese copy of the Honda GX35cc 1.3 HP - Manual included Bought for a project I had but never got around to it ... no longer needed. Don't ask me if it will fit your equipment .. if your not mechanically inclined it's not for you.
