sjgriz4 0 #1 Posted June 15, 2013 I have had this mower for years (dad bought it new) back in the day, it is a 312-8. When at full throttle and running it idols down all by itself, I can move the throttle back up and it stays for a minute or so then back down. Could it be the throttle cable or something in the card like a spring? Any help is always appreaciated. Share this post Link to post Share on other sites
WH nut 553 #2 Posted June 15, 2013 The rivet that goes through the throttle lever needs to be peened over a little bit Share this post Link to post Share on other sites
