Re: the best 49cc engine
Have a Grubee 48 cc and just received a Raw 66 cc. I have to say that the grubee came with better mounting brackets, and a variety of them, the Raw came with only two 1/8 inch mounting brackets, and no thick spacer for rear engine mount. Luckily I had left over from the Grubee supply. Also I drilled out the top throttle plate were the tab is located and drove a screw into the handlebar, a much more solid alternative to that little plastic tab wearing out in about a week. I thought the Grubee had a better fuel nipple coming off the carb, unlike the Raw just sticking straight up with no clearance for a thicker fuel line.
