I blew up the old 10 HP Tecumseh engine a few years back and put a Briggs 1550 on my TORO. Does anybody know if I can get a 10% or so oversize drive pulley to take advantage of the extra power? The engine drive pulley on my TORO is weird. It's kinda like a flywheel/pulley. It's heavy as **** that's why I said flywheel/pulley. I already did the impeller upgrade and tachometer.
