ouch! lol. the grommets actually don't do too bad, the kart still vibrates, but it doesn't rattle things loose any more! only thing i don't like is that when you pull the throttle, the engine sorta jerks to one corner, but it all functions good, i also made a few washers to tighten up one of the chains, and of course the other chain has a little chain tensioner i whipped up. oh and yes, the order is, head of bolt, mounting plate, fender washer, big rubber grommet, fender washer, home made washer (mom didn't want to drive to the hardware store), engine block, washer, rubber grommet, washer, lock nut.
p.s. i sure hope i remember correctly and my camera DOES have a video function! i did have a chance for a quick test though, i tapped the throttle, moved 3" before burring itself in the hole after doing a burnout on my gravel drive way!!!!! lol
EDIT: bleeding brakes takes for ever!!!! (at least on your first try, but i have no air bubbles!)
