312-8 Not getting fuel

Recommended Posts

oliver2-44

I'm new to this forum.

I was given a Wheelhorse 312-8 and mower deck that been sitting for 5 years, It' all there, minor rust, rotten tires, etc,

The engine is a12hp, Kohler 301s spec 47812 which makes it an 1984 model, The starter flange is stamped 12-84. The vinyl tractor nameplate is faded/unreadable. but I'm guessing this could be a 1985 1st year 312-8. Is there any tractor parts that have date stampings? 

 

I soaked engine in diesel for a week to free it up before I tried to turn it over, and it now turns over nicely. Cleaned fuel tank, replaces hoses and disassembled/cleaned carb. (need to order a carb kit for  a new rubber gasket) The engine will start if i spray fuel in cylinder, then I can keep it running by spraying fuel in carb with oil can, but it won't stay running on it's own. I disconnected the hose from carb and gas comes out when I spin it over so the fuel pump appears to be working. I checked compression and I get 90 psi ( I realize it has the compression release so hopefully compression is better than that).

 

On a parts diagram I saw some models have a hose from crankcase breather to air filter, but this ones doesn't. and I don't see an open hole/fitting for one Is that correct, or is something missing. this begs the question is there a crankcase breather somewhere that I need to clean?

 

Also, the starter was dragging, so I pulled it and found the front bushing very worn, worked some grease into it, and it works better for now. Has anyone found a source for replacement bushings and possible replacement brushes (The $220 price tag for a new one is a little steep for this project)

 

I appreciate any suggestions on my fuel/air and starter problems.

Hello Oliver and :WRS:

 

If you're getting fuel out of the hose to the carb and still have to feed it to make it run, something must be wrong in the carb.  "I can keep it running by spraying fuel in carb with oil can" tells you everything else is ok.  :handgestures-thumbsup:

Are you getting fuel in the bowl of the carb? if not then maybe the float needs adjusting? If you are getting fuel to the bowl then there could be a blockage in the carb. What brand of carb is it? Kohler, Carter or Wallbro?

The best I can tell the carb is a Kohler. Looking at the parts diagrams the kohler carb float has a round hole in the middle (like mine) while the Walsbro has a "D" shaped hole in the middle of the float. Does that sound right?

Have you done anything to the fuel pump? Prob need a new one. Get a Facet electric.

Aside from that wait for your carb kit before going any further.

      Hey all. I have a Electro 12 with a factory belly blade. It runs* and drives. I had used it to grade my driveway the last 6 yrs. Having moved I'm looking at my options on storing it or selling it. Frankly I have no idea what it is worth. I watched "ISaveTractors" video on 5 things to do with a new to you wheel horse/12hp kohler. (When i got it 6yrs ago) And went thru and did the adjustments and replaced the parts mentioned. It has been a good strong tractor for me until around July of this year. (2023)
      *Around July it started dying after running 20-30min. I replaced the carb (Chinese Amazon purchase) with one from isavetractors web site. That seemed to help it idle smoother(the old carbs jets wouldnt adjust), but it still dies at around 20-30min.
      So I've got 2 questions. 
      1. What is it worth? (As-Is) and
      2. What do I need to do to fix it? 
      Thanks yall!

      For Sale NOS M12S Short Block, still in the original box.  I bought it pre-emptively when Kohler was phasing out the Magnums.  Thought I would have it on hand if one of mine needed it, or maybe I would find a tractor with a busted rod for cheap.  Neither of those things happened, the darn things just keep running.
       
      Part number 77 522 35, probably built in late '05, it's the combination replacement kit Kohler made to fit WheelHorse or Gravely, machined to bolt directly into the Gravely transaxle, but also has spacers to mount WheelHorse PTO clutch/brake.  Also has a bunch of gaskets and seals packed with it, probably all you need to install it.
       
      And it's heavy, so it's not practical for me to ship.  Buyer arrange to pick up near Elida OH, I can lift it about knee high to help load.
       
      Asking $800 or might consider trade for a good center mount grader blade.
