CRE1992 135 #1 Posted July 24, 2011 So I just picked up a rough 414-8 last week, but I havnt played with it yet because it needs some work, it has a Kohler M14 in it. It needs a new muffler, fuel line, fuel filter, basically a tune up, and a rear axle seal. Does anyone have any recommendations on what else to replace? Also the fuel line is it 1/4"? and how many feet do I need? Sparkplug model number? And rear axle fluid? Lucas gear oil? Thanks, Charles Share this post Link to post Share on other sites
