I have read the section on transmissions and it seems the 2300 is not the best for racing, any particular reason why? Is it weak, geared low, etc. messing around with a old Sears custom xl10 with a 10hp horizontal shaft engine (tehcumsa) I know the spelling is wrong. Not looking to ditch this mower as it was free in my barn but if the 2300 trans won't work is there another trans with a horizontal pulley that would work in its place? Any help wod be great guys. Thank you
