STALLING ENGINE

Hello everyone,

I have a case 530CK with the gas engine with roughly 140hrs on it since a complete rebuild.

The tractor was running perfectly until i had it floated to my new lot. I loaded the tractor on the trailer no problem. The next day it arrived to be taken off started fine came off the trailer fine. Started up my driveway a 8-10% grade and it started cutting out and stalled.

My thought when it happened was that it was low on gas and the incline caused it to sputter and die. Looking back this doesn'[t make the most sense unless it was completely empty because the fuel line leaves the tank close to the driver position so an incline would push the fuel back to it.

That being said I filled the tank and had the same issue. I ended up having to tow it up the driveway. No up on flat ground it starts fine idles fine but under load it sputters and seems like fuel starvation to me.

I have taken everything except the carb apart replace the fuel filter and fuel lines. Could have i sucked some debris from the bottom of the tank into the carb causing the issue?

Any other suggestions would be great.
 
Fuel filter as in in line filter?? If in line and it is gravity flow they do not work well together. Either way good chance that the trip on the trailer shook up the gas in the tank and broke free some dirt/rust which is now in the carb clogging things up. You might get by pulling the carb drain plug and let fuel flow for a few minutes. The flow should be enough to fill a pint jar in less then 3 minutes
 
Get a flashlite and LOOK in the fuel tank. Does the tank inlet have a screen on it? Could be plugged. Also look for floating debris that gets sucked down over the inlet restricting fuel. Sediment bulbs usually have a fine screen in the top of them, check it out. If that all checks out move on to the carburetor. gobble
 
Update

Looked in the tank and its pretty darn clean.

Removed the sediment bowl and drain the tank. There was no clog in the tank nor in the sediment bowl filter.

So I moved onto the Carb. Took it apart seems pretty simple but was also clean no sediment or debris in there. I blew out all the orifices with my compressor.

Put it back together but it was got too dark before i could test it out.

Without finding any debris anywhere is there anything else that could have been bounced loose? in the distributor that could cause it to sputter under load?

Lots of things. But first I'd take a fuel sample and make sure it's not water instead of fuel. Preferably with the tractor pointed uphill so the water (if any) drains out the fuel line and into your clear sample container. If it's all gasoline, next I'd try to duplicate the problem and pull the choke while it's sputtering. If that improves the running then you know you have a fuel problem and you can quit worrying about points etc.. If no difference I'd check for a good hot blue spark that jumps 1/4" or more as my next move. If the choke makes things worse you're back to fuel, flooding instead of starving. Keep us posted!
 
I will try the choke to see what happens. I do not think there is any water in the tank or lines. Last night i drained everything and refilled with new gas just to be safe.

The float looked good. was not stuck and operated as it should.
I was a little concerned because the bowl was completely empty. I would have expected some gas to be in there.
 
What you said about the incline: it may be fine for leaving the tank, but does it go uphill after that? If so it could be that fuel filter as someone
else has said. I had same trouble with my VAC. I went to the parts store and bought a generic filter for a bigger Kohler engine, reasoning that is
gravity flow as well. Those filters are not quite as dense as an automotive filter that works under pressure. No problems since.

When it happened I removed the filter and put a new fuel line in and it didn't fix the problem.
 
Ah but did you do as I said and pull the carb drain plug and make sure you had a good steady flow of gas that would fill a pint jar in less then 3 minutes??

As for the sediment bowl not fill that says the carb was full of gas and the float was up and the needle valve is sealing like it should. So due to the fact the sediment bowl was full of air and the line shut off due to the float then gas could not fill the sediment bowl.

As for an in line filter most are made for a system with a fuel pump and need around 5PSI or more to push the gas threw them and a gravity flow system has no where near 5PSI

Thread resurrection as I finally have had time to look at the tractor. so the last thing i did was clean everything sediment bowl tank and carb and nothing seemed to be gunked up or dirty. I had it running and it idle's fine, i pulled the choke and it bogs down and almost dies. Could this be a carb adjustment issue?
 
The carb adjustment shouldn't have changed. But one grain of sand or flake of rust could cause it to starve out. Or run overly rich, for that matter. Does it blow black smoke when it's dying? You said you pulled the choke when it was idling, what I meant was that you should try that as it's dying and see if it helps or makes things worse. Will it restart after a few minutes after it dies, or do you have to wait a half-hour or more for it to cool down?

It will start up right away. No smoke when its sputtering and dying. I'm going to get a video of it today and will share a link so you guys can see.
