rob65 0 #1 Posted February 26, 2011 This is a picture of the carb on my 312-8. It does'nt match the diagrams shown on partstree for this tractor (1988). Is the needle broken? If not how do I remove it for cleaning, or do I? Thanks, Rob Share this post Link to post Share on other sites
rmaynard 14,933 #2 Posted February 26, 2011 It appears to be a Walbro, which is not adjustable. Kohler was required by the EPA to put less-polluting carburetors on their engines, and that is what you have. Share this post Link to post Share on other sites
Kelly 1,028 #3 Posted February 26, 2011 Yup, me I pitch the walboros and put kohler carbs on with the high speed screw on top. Share this post Link to post Share on other sites

rmaynard 14,933 #5 Posted February 27, 2011 I think your M12 can accommodate a good used Carter #26, which should be available at a reasonable price on eBay and other sources. You should be able to pick one up for under $30.00 Share this post Link to post Share on other sites

Duff 206 #10 Posted February 28, 2011 Rob, for what it may or may not be worth, I'm running stock Walbro's on three Magnum engines. The only problems I've ever had have been related to dirt. After really cleaning the carbs thoroughly and being sure to change my air filters on a reasonably consistent basis they've been running sweet. Just my two cents worth! ~Duff Share this post Link to post Share on other sites
