Once it starts it seems to misfire or something. I provided the video to help you hear what I'm dealing with!

take the bowl off the carb, probably condensation in there from the ethanol fuel it will actually raise the float level and cause  it to flood, i surmise that how it happen don't know for sure, but i know that i have fixed my neighbor's B 80 several time for same symptoms by doing this. first time i pulled the carb all the way off but after that i got smart and just drop the bowl and fixed it that way. clean the inside of the bowl and careful of the bowl gasket and make sure you start the bolt back in the carb straight. i bought a 312 one time that somebody did that to almost had to buy a new carb. good luck

What he said!

How old are the fuel lines? They do break down. It's worth $5 to replace them and use an inline filter as well.

Thanks for the input so far! 

 

I tried emptying the carb, havne't had a ton of time to play with it. Also, the fuel lines were replaced last winter with a new fuel filter; as well as a new fuel pump.

The screw on top of the carb...screw it in until it "gently" bottoms out...pay attention to how many turns it takes...might be like 2 1/2 turns.  Then pull that screw out...there is a little hole down near the bottom of the shaft of that screw.  Using carb cleaner and a small piece of wire, clean out that hole.  Put screw back in by bottoming out and the backing back out the revolutions you counted in the first place.  If that hole is clogged or dirty...it will do what your horse is doing.

 

I would also take a look at your points...should be .0020...I like about .0018 on older machines.  The points control your timing on these Kohlers.  Hope that helps.  :)

Also make sure your condenser wire hasn't broken. (It happened to me! )  :)

That is an Magnum 14 or so he posted, won't have points or condenser. Carb., fuel pump,  fuel filter, gas lines, screen in tank or tank cap not vented,  When you get it running and it's still miss firing the valves may need adjusting.

My Magnum 12 ran fine but it had a constant miss fire. I found the intake valve was at less then half of the specified setting..

Try a new plug before doing anything.  Mine just did the same exact thing and I wasted a lot of time for not.  The plug was replaced in DEC.  Fouled out this weekend.

 

Looking at your other videos, you had some fuel problems going on as well.  Did you ever solve those?

Fordiesel69 - I did solve them! Found the screen in the tank junked up, replaced that. Ended up replacing everything between the tank and carb. New fuel lines, inline filter, even new fuel pump! 

 

I'll be sure to give the spark plug a try.

So the bowl clean out worked! 

 

Anyone know where to get a rebuild kit?

Stuck float or float valve will cause "flooding".

ethanol gas condensation build up in the bowl will also cause this i know you said you just cleaned the carb but if it was in the gas tank it could end up in the carb again as fast as you clean it out. good luck

      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.

      Tractor features Kohler 16hp cast iron engine, gently used 42" deck, concrete wheel weights, tire chains, new Chinesium carburetor, fuel lines and filter, new air filter, 2 new fwd/rev cams.  A starter,  some new gaskets, and miscellaneous parts.  New drive belt and all the belt idler assemblies.  Engine runs but smokes.  Great restoration candidate or a spare engine for you pullers out there.  Call, text or email for a private showing.   No offers considered unless made in person.  Buyer responsible for transportation.  Many more pictures to send to interested persons.

      1979 C 8 speed tranny model with 14 hp Kohler engine and plow attachment, Runs good but ignition switch doesn't work and have to jump start over solenoid. Right rear wheel hub lock bolt won't hold and hub slides in on axle. Not sure why, out of round hub axle hole? Still use it regularly though with hack fix. Plow blade is badly worn out along the knife edge.

      I think I am selling my 1987 414-8 with plow, weights and chains.  Now here’s the story on this one. A long long time ago, I was searching for a snow plow for my 416H.  In that search I stumbled onto a forum which was one day old.  There was no name of the forum, just whtractor.15.forumer.com. Trying to learn more about snow plows I started conversations with one of the active members on the site, let’s call him Mike.  Mike convinced me I didn’t need a plow, but an entirely new tractor.
       
      About a week or so later, I found this 414–8 for sale, and bought it.  I now had my plow and could plow the driveway. So what happened with Mike @Sparky and this forum I spoke of? It grew a little bit, and we now call it RedSquare, and for sale is one of if not THE reason RedSquare exists today, so you can own a piece of RedSquare history!
       
      About the tractor: 1987 414-8. Kohler M14, runs well does not burn oil. Everything on the tractor works as it should, but it is a worker. The plow is a 48” with a custom made scraper blade, made from heavier stock than original. For the past several years, this has been a dedicated plow tractor, so it hasn’t seen a lot of work, but has also sat outside (under a tractor cover) so lots of let’s say, patina going on.  
       
      I a, selling because I just picked up a 416-8, and that will become my winter plow / blower tractor.  I am looking for $550, but like I said this tractor is a bit of a legend!

      I have cleaned it up since the pictures were taken.
