I fully believe you. The fact is the 034 and 036 are waht 4 generations old, and had ancient cylinder designs, I would expect them to get out performed by modern saw of similar displacement ported or not.What finally convinced me to try a 562 was watching a stock one out cut a ported 034 super and ported 036 booth done by a more then reputable guy, I can provide you with names of the other guys at the same gtg who all agreed, all running round chains, just send me a PM
