grnlark 489 #1 Posted April 7, 2010 I know the Kohler K90's are hard to find and original for our RJ's. If anyone is willing to make the drive to Reading, PA, there's a guy with a 2 wheeled walk-behind for $200 with a K90 on it. I'd hate to see the walk-behind scrapped, but the motor alone would be worth it if your looking for one. Philly, PA Craigslist 1679879723. Share this post Link to post Share on other sites
