That's why I like and trust your opinion so much, because you tell it like it is, and you always give credit where credit is due. Nothing is 100% perfect all the time. Some things are just less prone to problems than others. The only engine that I ever sold and later regretted was an "Zenoah" G62 fitted with you ignition. I won't say it was faster, but I will say that it got "Faster" "Faster," and didn't gurgle all over the place doing it. That was the Zenoah that I would put up against any DA 50. I don't want to beat that horse to death again, but that's just the plain truth.
