Big Sale Has Started - UPDATED 07-31-25 (01 Apr 2025)
As some of you know my dad passed away 2 months ago today, on May 31, 2025. I posted it in the Members Only section when it happened. Thanks to all of you who have offered kind words on the forum, with phone calls, and visits in person during this time.
The Big Sale is on but not like originally planned, it is a by appointment type of thing now. I don't have the manpower, or the desire to do a big event like originally planned, I just need to sell a lot of parts that are taking up too much space here. I have been told and believe we are overloaded with Wheel Horse parts like no one has ever seen. Peeps have already been coming in from different parts of the country and buying a lot of stuff due to seeing the sale page, and seeing we are the only Wheel Horse only business in the USA that does things on the scale we do. The sale will continue for awhile until I free up some more space but you may not want to wait too long as things are being sold every day and there are limits to how many of certain parts will be sold.
As it says on the page it is still under construction and the page isn't finished yet. I've had a ton of calls for parts and the Big Sale Page may help answer some questions about what is here before peeps call. I hope that page is also clear that we DO NOT SHIP anything... This is a by appointment type of thing now. Be sure to call before you come to make sure the day isn't already full with peeps scheduled to come in, and make sure what you want is still available.
My 520H has gone hunting - needs some help

If I disengage the PTO, the big Onan runs just fine and I can get it back to the stable without issue. I've repeated this about 4 times now.
What I've done so far.
1. Carb was cleaned about 3 weeks ago. (My usual spring chore)
2. I changed the oil and filter, blew out the fins, and cleaned the air filter
3. Installed a new electric fuel pump.
4. Checked the plugs, they look just fine and are properly gapped.
So I thought, I must be the new electric fuel pump. So I disconnected it and put the gas lines back on the stock pulse pump. Ran the tractor and had the same problem. So its not the pump.
I've had carb cleaning fix an idle surge many times and I plan to clean this carb again. I would put in a kit if the price wasn't so darn high.
Any other ideas?
Thanks,
Kurt

BTW, I checked the electric fuel pump before I disconnected it. Plenty of flow, but the pressure seemed low, but my gauge was acting up. Time for a new one.
Thanks,

I also cracked the fuel cap in case the vent was plugged and that did not help.
I quit mowing and returned to the stable. I broke out my propane torch and played the unlit torch around the base of the carb and the intake manifold. No change in the engine.
About the only thing left to try now is some Sea Foam or MMO. If that fails, I'll pull the carb and put it in a can of carb cleaner for a few days.
Ugh!
Thanks for the help.

Worth a try. Stay tuned, but it might be awhile. I'm traveling for the next week.

Both of my Fords have this kind of strainer. It is amazing how much crap gets on the screens.

The manifold and carb gaskets are on order as is the gas tank valve. So I'm in wait mode.
Since my sinuses cancelled my trip the show, I had some time to pull the carb and clean it as best I could. Now it is sitting in a can of carb cleaner until the parts get here. I wish these new cans of carb cleaner were a good as the old one. Maybe a few extra days will help.
Once I get it back together, I'll run some Seafoam through it and hope I got it.
Thanks for help,
Sorry I had to miss the show.

I soaked the carb in a can of carb cleaner for two days. It came out a clean as a new one. I blew out all the passages with compressed air and then carb cleaner. I also replaced the fuel and vacuum lines as well as the fuel filter. I also replaced the valve/screen on the bottom of the gas tank.
I was hopeful as I started it up. After 5 minutes of mowing, the hunting was back. UGH!
So I replaced the ignition switch, the connector looked good and started the 520H and I saw some improvement. I would say more than half the problems are gone. So I put some Sea Foam in the gas tank and started mowing. The seem to be reduced quite bit.
My plan for now is to mow for a few weeks with Sea Foam. I will also be checking all the electrical connection. No infamous 9 pin connector on the 1988 520H so that is not it. But there are other connection.
Thanks for all the help. I let everyone know how this works out.
PS this Onan has almost 1200 hours on it. Any major problems and a repower will follow.
