This is my very first engine to be converted to gas. It wouldn't have been possible without the help and good advise I got from these forums. Also Hats off to Ken Lambert for the exact fit parts needed to make this a gasser. Most of you know his website, but for those who don't and interested in converting a Supertigre here it is.
