No fuel la130

[gmsaintsfan]

I was cutting my yard and my tractor just stopped. I have fire but no fuel, I replaced the fuel pump, fuel filter and the only way it will start is to pour fuel into top of carb then it dies as soon as this burns out. Is there a switch that controls the fuel on this model??

You need to start tracing it back and find out where you arent getting fuel.

Personally, I'd start by unhooking the fuel line from the carb. If it is an electric fuel pump, simply turning the key ON should make fuel flow out the hose. If it is a mechanical pump, you may need to crank the engine over. Of you arent getting fuel, go to the next place there is a connection.

If it is a mechanical FP like on the side of the motor, it is possible that there is a hole in the line between it and the tank. Then it would only be sucking air.

Why kind of fuel pump is it?

 

[gmsaintsfan]

It is a mechanical fp. Its is putting fuel to carb but not thru it. Is there an electrical switch of any kind that can go bad on that model?

Not sure if it is related to your problem, but when I bought my JD
riding mower, the dealer said to open the gas cap if it shutdown.
Seems they were having many coming back into the shop and the
only problem was the gas cap causing a vacuum. Replaced the
gas caps and everything was fine. Luckily it has not happened to
my unit so far.

Thanks I will go try that right now!!

I can pull fuel line off and stick into top of carb and it runs. I guess a jet may have trash in it??There is something electrial on botttom of bowl where you would see a drain bolt....wonder what it does?

 

[gmsaintsfan]

That wasnt it, but thanks

Figures it wouldn't be that easy.

Yep, sounds like a plugged jet to me. Not sure what the "electrical" thing is you are talking about. But it sounds like the carb is in need of a good cleaning

There is a fuel solenoid on that carb, according to jdparts.

Not sure if this is some EPA crap or CA stuff added to appease the "can't do that's", but will be good to be sure it is working and allowing fuel to flow. Can't say for sure how to check it out.

This fuel solenoid may shut off the fuel if the mower deck PTO is engaged. Just wondering if you are sure it is disengaged, on the chance that the two are connected. Wierd way to do it but then these safety tricks are wierd to begin with.

Look at the fuel cap on the tank.
If it has a little hole in the center, it has a tendency to get clogged with junk.
A lot of times it will look white, from our glorious $4/gallon fuel.
We stick a paperclipwire in ours and it fixes the problem. Don't punch it through the rubber breather underneath, just clean the hole. Bee's like to put mud in there too.

The most common problem on B&S engines with exactly your problem is a sticking float chamber needle valve. The plastic with rubber tip valve needle deteriorates and sticks, shutting off fuel to the float chamber. I could unstick mine by using a compressor set to 30 psi and blowing into the hose going to the carb. I kept thinking it was water in my fuel or some other problem, but finally ordered a new needle valve and got one made of brass instead of plastic. My JD dealer told me that this was one of the most common problems on these mowers. Your problem sounds just like this. It could be a fuel solenoid problem, but I'd bet it's the needle.

You can check operation of your fuel solenoid by turning the key to run (parking brake set) and disconnecting/reconnecting the spade adapter on the electrical wire to the solenoid on the bottom of the carb. It should click loud enough to hear and you'll probably feel it too. If it does, the solenoid is most likely good and working fine.

i have an la135, same tractor, and same problem, is there a way to clean the carb jets without taking the carb off and is there a special tool if the carb needs to come off? it looks like it has a star shape head on the end.

Kepo57, read this thread and go to this link for carb removal and installation details. Yes the the screws holding the intake manifold to the engine are star heads and the wrenches are included in most driver bit sets.

Is "star headed" what we call "torx" up here?

Yep! Since the person asking a question called it a star, I kept his terminolgy. He's struggling enough trying to get his mower running without my correcting his tool nomenclature. After all, even Wikipedia says that people often use "star bits" when they are not familiar. It's also called hexalobular, but that sounds like something the TBN inappropriate word filter would catch.

Is that thar one of them knots on your forehead that a witch might have put there?

Not questioning his vernacular, I just wanted to know if it was the same as torx. There are so many crazy shaped wrenches and screwdrivers anymore.
I had to buy a size 20 torx last week just to change a tail light bulb in the jeep. No English or metric allen wrench would fit without stripping out the head and causing further problems.

Carb solenoid has a rubber piece that is glued to the solenoid plunger. It comes loose and plugs the hole. When the engine shuts down and the key is turned off the plunger pops back into the rubber piece. Engine will start back up and run until the rubber piece comes loose again. The fix, remove the rubber piece. Problem solved. That is an anti backfire solenoid, but I bet you can't tell the difference with it removed.
