Margie 16 #1 Posted 5 hours ago I just bought a 312-8 today! Already love it although I haven’t mowed yet. What is the best spark plug I can use (Champion RH-10C?) and the best transmission belt? I don’t mind spending a bit to get the best quality. Thanks in advance! 2 1 Share this post Link to post Share on other sites
ineedanother 2,634 #2 Posted 4 hours ago Excellent! We'll need pictures. We love pictures. The RH-10 is the correct plug and you can cross reference easily to other manufacturers. You'll have questions, everyone does but I have a 312-8 and it could very well be my favorite. Great machine! Here is a recent thread similar to what you'll be asking. 1 Share this post Link to post Share on other sites

Have a model number and serial number off the rear seat pan? Will link you to the appropriate manuals. Share this post Link to post Share on other sites
