Achto 28,917 #2 Posted May 17, 2017 Vanguard engine would be a good choice. Some have also used the Predator engine from H.F. Share this post Link to post Share on other sites

MalMac 1,332 #4 Posted May 18, 2017 I've got a friend that had re-powered two of his 520's with the Vanguard from small engine warehouse, he's had no problems and likes them. 1 Share this post Link to post Share on other sites
