I have found an older Billy Goat blower with a 13hp Honda, Will there be a noticible difference in pile pushing with the 13hp Honda compared to the 8hp billy goat blower? Say a 13hp is running @ 4600rpm and a 8hp is running @ 4600rpm, is this comparing apples to oranges? 13hp a Monster to push? Weight wise? Guy down the road has one willing to sell to me for 200 bucks, but I'm not sure if I should get it as it is older, like 6-8 years old or so, said the motor has been rebuilt about 4 years ago, starts on the second pull. Blower unit it's self is rusty, pretty rough, but 200 bucks is fair isnt it? Any opinions or suggestions would be appreciated. Thank you!
