I recently bought a saw on ebay that was supposed to be a 920. After further review and some measuring tools I found out it was an 820. The next day did some matching up and decided that the jug bolts up the same and stroke is the same. so i put the 820 jug and piston on my 920. The saw ran great and could tell no difference in power because in all reality i was only loosing 7 cc. so if your 920 blows up this maybe a different option. you guys probably already know that but it tickled me when this worked out for the best.
