I have a 1978 (I THINK) snapper sr1433 rear engined with a 13.5 briggs and stratton 5 speed aftermarket engine. I would like to turn this into a racing mower/super fast runaround go cart. Super fast or not, i am going to take the deck off and spraypaint, and the drive disk is trashed. Ordered one, getting here soon. Can i have any tips and/or tricks? Ive been reading about taking the governer off, what do i need to do structurally? Thanks!
