the thing with snappers is... most of them are configured so they can be stood up on the bumpers in the back for storage or servicing of the blade. Your conversion needs to keep that in mind. Notice where the oil intake pipe is. That needs to be at the back or else when you stand it up... its going to dump oil! If that was the B&S single of the same hp... this would be absolutely painless. I will be curious to see if you get this worked out. Assuming you can get the motor situated the way it needs to be (or you decide against standing it on end in the future), the only thing you may have to worry about is wiring. I did all this on my snapper zrider (13hp 28707 to 19hp single). wiring was my only issue, had to add a wire for the carb solinoid and alternator was slightly diff.
