Have you tried adjusting the main jet needle? It's the one that points straight down out of the bottom of the float bowl nut.

Jep i did, when i turn that open (now it is about 1 and 1/2 turn open) from 2 it starts shooting flames true the exhaust when rev up and back to idle. ;-)

spark plug have the right color so i think mixture is good.

when i hold the arm i can feel it pushing.when u put a small screwdriver inbitween, it runs normal... I'm starthing to think the governor have a problem.

no wthe engine have not enough revs/power to mow.

riding is just possible but it's like riding a camel. (lol)

Governor spring needs replaced is a common cause of that.

      Wheel horse c-125 with kohler 301 engine wont fire but turns over. I have made sure there is fuel getting to the engine and there is a strong enough spark to start it. Also we have good enough compression.
      So what is the problem?

      Hi Everyone,
      I am not selling this easily as the loader on this machine was the find of my WH collecting daze! 
       
      For sale is a 1991 WH 520H with a 1970's Wheelhorse ARK Industries Loader, sub frame and the weight box. The clock on the 520 shows 1183.8 hours. However, the engine was bought off Ebay and I had it shipped to Pennsylvania from Michigan. This Onan P220 had less than 800 hours on it and I have put 40 hours and some change on it since installing years ago. (It doesn't get used a lot)! Before installing, I de-carboned it and replaced the top-end gaskets.
      I need room for home projects, space in the garage and I picked up another loader tractor of orange color so this one has to go. What's wrong with it!? Well first off, everything works as it should except a gauge light is out on one of the dash gauges. The gauge works, You just can't see it at night. One of the pivots on the loader left side is wallowing. It's not bad but it is something that I will mention. There is a small seep from the left side bucket dump cylinder hose connector. The tractor is also is a ***** to start if it sits awhile.
      What is right with this machine? All the gauges work! All the lights work! It has the forward swept front axle which makes turning with a loader wonderful. It has the heavy-duty front spindles so it can handle the stresses a loader with weight will induce on a tractor. The bucket is as solid as you can get and built heavy-duty! With the weight bucket full and with the 26x12x12 rear tires/rims, you won't get stuck unless you really try or are in some seriously bad terrain. Though this tractor's speed and direction is still controlled by the steering wheel lever, you will also get a complete foot pedal conversion kit I bought a few years ago on RedSquare and never installed. The motor runs great! The tranny is powerful cold, warm or hot! The loader works 100% and can handle many tasks least of which is snow removal.
      (Now is where I start to sound like a late night commercial)
      You will also get the original Onan P220 motor, (rear cyl valve seat went), with all the parts intact including the muffler, coil and fuel pump, PTO, etc. It can be rebuilt if you so desire.
      (If you buy it now)..............
      For the asking price, you also get a complete 1992 WH 416-8 that is 100% mechanically sound. (Electrical gave me fits so it has a push start).   It looks like hell and a tire loses air but it runs and mows great and starts each and every time. It comes with a 42" SD mower deck that works well. The Onan P216 runs great and has good compression in both cyl. If anything happens to the 520H, the 216's motor can be dropped right in!
       
      I really need both these machines out of my garage and storage shed soon. I have NOT offered this on Craigslist or on our other popular classified website here in Central Pa yet. What I really want is for someone on Redsquare to buy it and take care of this machine. ARK Loaders are getting scarce and this unit runs great. I just don't use it as much as I though I would and having two loaders is nuts when space is tight.  This machine has never sat out in the weather since I have owned it. (Almost 10 years). It has always been serviced and regularly maintained. It hasn't mowed grass in 5 years!
      The price is negotiable but I don't want to give it away. I won't ship it either as it's too much to take on and I'm busy as heck!
      Emails or PM's. I'll check in a few times a day until it is sold  or if no takers, it goes on the block to someone who most likely won't care much about it!  
      If you have any questions, let me know. More pictures are available if you want to see something up close and personal. Here are some of the views I took this afternoon of the loader/tractor. $2500 or best offer. Give me an offer. I'm not criminally insane. I'll counter or just say no. Just be serious folks. Thanks!
