Hauled Home a Beautiful 312-8

[Mike'sHorseBarn 3,626]

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!

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.

That 12 HP is a fantastic worker.  

Some of em just have to stay around.

Nice score on that 312-8. Mine is my go to mowing machine, so I definitely agree with you,

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.

Very nice Mike. Enjoy the tractor!

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?

I think that may be a Walbro carb.  Had one on the 1988, 312-8 I sold last year. Any pictures of the carb?  Tried to replace it with a Kohler carb before I sold it, but the air cleaner plate was different.

@ 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

Its good and tight. I'll grab a pic of of it. 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

So long as the choke and throttle shaft tabs are the same it's a direct swap. 

 

I've swapped the shafts before just to make them an easy changeover.
