800 dies out (intermittent)

New User
Just got this tractor and have started it just a few times and briefly used it twice for snow plowing. Starts GREAT--quickly, just a bit of choke, idles well.

Seems to run fine after warm-up (I'm located in Wisconsin--its been cold)-- I can drive around my property, apply different amounts of throttle, start/stop, etc. and its all good.

On Both occasions I plowed, its started fine, drove around fine but stalls out and dies after a few minutes which seems to be related to operation of the loader (raising/lowering/dumping the bucket).

It restarts only with full choke but runs rough as if it doesn't have full power when choked. It dies when I release the choke.

The only remedy is to turn it off and let it sit for a minute or 2. Then it's starts with no choke and runs fine...until I load it down with loader operation.

Not sure about state of tune-up, fuel quality, etc.

Suggestions?
 
YOU HAVE A FUEL ISSUE. COULD BE CARB OR RESTRICTION IN THE LINE, SHUT OFF VALVE.ETC. WHEN YOU SHUT IT OFF FOR A COUPLE MINTUTES IT ALLOWS CARB TO BECOME FULL. ENGINE STARTS OKAY BUT WHEN YOU PUT IT UNDER ANY LOAD THE GOVENOR OPENS UP AND YOU HAVE TO MUCH AIR FOR THE AMOUNT OF FUEL YOU NEED. THE CHOKE WILL FORCE MORE GAS TO THE CARB. I WOULD CHECK THE FUEL INTAKE FIRST.
 
Sounds like a normal cold blooded Ford to me. They have to warm up for at least two minutes or they keep drying on you.
 

Since it quits under load after warm-up it is fuel restriction as Pinball said. Check your tank. I have cleaned a lot of crud from tanks by simply siphoning. There is a screen on the inside of the tank tap. Check also for an aftermarket in line filter. Once you think you have eliminated problems, shut the valve, remove the drain plug at the bottom of the carb, and catch flowing gas in a can. You need to get a pint in a half minute.
 
If you are getting a lot of snow blowing around from wind while you're operating the loader, it could be that the carb is icing up. You could try making a "cold shield" for the carb out of aluminum foil to keep the wind blown snow from getting directly to it and to keep in some of the warmth. Try including some of the exhaust manifold inside the foil to get some extra warmth to the carb.
 
for sure sounds like a fuel delivery issue.. whether it's an iced carb or plugged valve/strainer.. it's something making it
lean...
 

I appreciate everyone's responses.

Pinball--what is the process for checking fuel intake?

Here's my punch list: check fuel intake; check for restriction in inline/after-market filter, tank crud, shut off valve; macayver a "cold shield".

Thanks again,

jeff
 
Check to see how the fuel line is routed, if its routed to close to the exhaust manifold, it may be fuel locking from heat..

Test test 123, I gave you the procedure.

Update. I was able to spend some time on my fuel issue and got a temporary reprieve, inconclusive causes, future issues.

Temp is in low 40's today -dry and sunny today. I started tractor and it ran rough without choke after 3 minutes warm-up. I shut it off and started test procedures.

The filter is missing from inside the tank-- could be root cause. I siphoned as best as I could around fuel inlet inside the tank. I also exercised the shut off valve under the tank several times. There is NOT an inline filter.

I removed drain plug at carb and got only 1/4 cup in 1 minute. Replaced the drain plug and restarted.

Started easily and immediately ran well with no choke. After 2 minute warm-up I took it for a spin and exercised the loader bucket (up/down, dump, lift, etc) 10 times or so and it did NOT load down and kill the engine.

In summary--It showed very low flow even after I siphoned tank, exercised shut off and removed drain plug ......but ran normally under loader operation.

Thoughts?

I do need to drop and clean the tank, replace the shut off valve, probably replace the after market fuel line. See attached photo--the fuel line is routed close in around manifold and muffler--previous owner added the aluminum shield.

Your gas flow is certainly slow. It is too slow for heavy work. I don't know why you need to remove the tank. Sheet metal removal is a time consuming tedious job. Have you cleaned the filter bowl screen and the carburetor idle screen? They are not either of them definitely there as they sometimes get removed and not replaced.

Thanks. I was going to tackle the filter bowl screen today. Wanted to check that I had a replacment gasket before I started.

I wasn't aware of the carn idle screen. Don't see it in my service or parts manual diagram. Where do I access that?

Sorry, that was supposed to be carburetor INLET screen. The original fitting that threads into the carburetor inlet had a screen on it but it could be long gone.
 

No inlet screen. I didnt drop the bowl --I need to order a bowl gasket.

I did notice a dime size chunk of crud floating in the bowl that was not there last week. Perhaps that was the obstruction causing the original problem --seems unlikely but perhaps I dislodged it when I was futzing withe the tank, valve, etc.
 

Update- over this past weekend I worked on the running rough / dieing out problem and it seemed to have resolved itself. The weather was mid 4o's and sunny. I ran the tractor thru its paces (driving, raising/lowering loader, dumping bucket, raising the front end with the bucket, etc.) and could NOT get it to die out.

We got a snow dump last night and the temp is in the mid-20's. Tractor started right up and I let it warm-up for several minutes. Then it reverted to the previous problem-- every couple of minutes while under putting it under strain (pushing snow, or dumping snow or going up an incline) it would run rough for a moment and then die out. I can keep it going by pulling the choke out but it would not go back to normal. It will not restart without choke. I can immediately restart with choke pulled but it wont resume normal operation regardless of how long it runs choked.

The only way to resume normal operation is to shut it out off and let it sit for a minute. After a minute--it starts and runs fine until I start loading it down again. Then rinse and repeat.

I was outside for about 15 minutes and had to let it sit and restart it about 10 times.

One thing I noticed is that as it is starting to die it smells like strongly like partially burnt gas. After it dies and I'm waiting to restart-it smells strongly like gas--as if its flooded.

Could it be a flooding issue rather than a fuel starving issue?

Could it be temp related (worked fine when it was 45, dies out when its 25)?

Thanks for looking.

Good morning. I did give results in a previous post:

Ran fine on Saturday under load. last night had all the original problems under load. IThe gasket bowl gasket and screen will arrive today and I inspect and install new soon.

Thanks,
