ole496 0 #1 Posted December 3, 2008 I have a 20 HP Onan Performer model OL20 H251H. I would like to get a repair manual and parts list for this engine. If anyone knows where I can get one or download one please let me know. Also, can anyone recommend a great website to order parts for this engine? Thanks, Mike Share this post Link to post Share on other sites
