I can think of no reason to do that to an old block, new block different storyI have been told it is not legal for clones by NKA. As far as the animals I have also heard no one here. But flathead you can I would assume do to lack of blocks still being made
And WKA says re sleeving blocks is legal in all briggs and Stratton classesMost all organizations that offer the animal and flathead are governed by WKA rules. Something you guys are forgetting. Just because it doesn't say you can't, doesn't mean you can.
