Looks good on you offering a discount to help him out..that`s looking after the customer..
But.......i`ll say this..i`ve rebuilt a pile of engines,,i know ring gap has to be checked..a newbie isn`t necessarily going to though...
I still think if you are selling to backyard mechanics/do-it-yourselvers and are suppling the piston/rings and cylinder.........then the supllier should gap the rings...they have the means and knowledge to do so and can take this out of the hands of the first time builder.......yes the builder is responsible...but this would go a long way towards ensuring this wouldn`t happen ..
