gwest_ca-(File Mod) 11,393 #2 Posted May 5, 2020 Welcome to the forum. The 310 went from K-Series engines to M-Series with magneto ignition. They went from 3 amp unregulated charging system to 15 amp with voltage regulator. They added a low oil circuit to starting system. Not much to the wiring harness on the 310 because they did not have the idiot lights. Very simple to reproduce. Garry Share this post Link to post Share on other sites
