hello im mikey walsh, i live in wisconsin, and i farm with my dad. i have a simplicity 738 8hp, i have recently seized the engine on accident and so i have upgraded the engine to a kohler 13 hp engine, i had some prblems at first with the belt being to tight cause the crankshaft is a little farther back so i have to get a bigger belt. but i wanted to ask yall.. was this a bad thing to do??? i think it might make wear and tear on the transmission. i am also going to do some costomization just for fun lol and that includes changing the muffler to a straight pipe, i mostly use this tractor for the strawberry patch amd garden tillage, thank you
