Mike'sHorseBarn 3,623 #1 Posted 16 hours ago Picked this 312-8 up this morning! Might be the nicest original one I ever bought! Has a bagger and a plow thats just as nice. Got it running after a carb clean and new fuel lines. I was just gonna flip it, but I don't know about that now. It works pretty great! 20260801_170738.mp4 15 Share this post Link to post Share on other sites
JCM 11,295 #2 Posted 15 hours ago Big 312-8 fan here. Have had mine for 37 years. I can mow my yard 3 times compared to once with my Kohler Twins on the MPG. Good luck with it. 4 Share this post Link to post Share on other sites

MainelyWheelhorse 2,912 #4 Posted 13 hours ago Nice score on that 312-8. Mine is my go to mowing machine, so I definitely agree with you, 2 Share this post Link to post Share on other sites
Mike'sHorseBarn 3,623 #5 Posted 12 hours ago One thing I don't like about the carburetor on this though is that it has a fixed main jet. Didn't know they had those 40 years ago. My 314 is adjustable. 1 Share this post Link to post Share on other sites

Didn't know they had those 40 years ago. My 314 is adjustable. Check the top & bottom hole 🕳 for the throttle shaft. If it's not loose it'll rebuild and clean up well. If the shaft is loose in the bore - toss the carb and replace. I wonder what, if any, adapting needs doing to use the fully adjustable carb? Share this post Link to post Share on other sites

Tried to replace it with a Kohler carb, but the air cleaner plate was different. 3 Share this post Link to post Share on other sites
peter lena 9,962 #9 Posted 3 hours ago @ Mikes Horse Barn, great pick up on that ! regular for me on any pick up . is to , quickly / easily get a paint save going on ? like a penetrating oil spray down , let it soak in a few days , then wipe it down with a , soft clean cloth , next stage , rubit down with clean miner oiled cloth , that paint condition , should pop right thru , any grunge . preserving / enhancing what you have is , is vital , after that , a clean mineral oiled cloth rub down , will keep it looking fresh . those plows , really really come to life , with QUADRANT SWING ACTION , DETAILING , SQUESE LEVER START, DETAILING , very easy , luck you ! pete 2 Share this post Link to post Share on other sites

If I was going to replace it I'd have to find a other walbro. I believe the correct one would be a walbro #52 1 Share this post Link to post Share on other sites
