Our Dyno guy has done a few but not a lot and says about the same thing for the 235/261.(he also talked me out of getin a 261 he said i see very little gain on the pump)He said 110-125 stock and the most he has seen is 205 normally 235/261 with a slight cam tuned correctly 140-180.Interestingly he said he has seen 2 daul carb 235's that he did not put together pull 95-100 HP ,the guy that built them was really embarrassed as he bought the latest greatest inline parts on the market and had done something wrong.Who really cares about HP with these little lawn mower engines anyway.Its the milage and how smooth they are (plus they run dirt cheap)that has sold me.I want to know who all the dummys are that would bother to pay 350 for a cell to put one on a dyno.
