My question is, can a Kawasaki, model FD671D 23hp water cooled engine be rebuilt? Bored out, new oversize piston and rings, rod bearings, valve guides, seal, the stuff needed for a complete engine rebuild. I have found a new factory engine however it’s nearly $2000.00 including shipping. I have not found much in the way of new parts for this engine via the Internet. Looking for some good advice. Thanks.
