I don't see a need to tell Rick anything, I don't bash my competition. I do find it interesting how your trying to divert a potential sale from a vendor on this site, but it's all good. My question for you is if you really think your 8.0 (.50ci) is making 50% more bottom end pulling your kid and wagon, at say 70lbs on the high side, how much of an increase do you think this 5.9 (.36ci) makes being it pulled 50X+ the weight of your engine? 1250% more lol. To claim he's "the best in the business" is totally a bias suggestion if you haven't tried anyone else. I have customers who have tried both, and their observations are quite the opposite of yours
