LT 2000 stalling issues

So I have a weird one going that I could use some help with I have a Lt 2000 with an 18.5 intek engine that has been stalling out. There are a couple of weird items 1. mower runs fine for 15 minutes then stalls like it is running out of fuel but as soon as it shuts off you can turn the key and it fires right back up and last for a few minutes then it does it all over again. 2. I noticed that the oil filter is smoking hot after this process has gone on for a while.

the oil level is correct new plug, filter, lines and battery. no idea at this point a local repair guy thought I was losing the head gasket but i am producing no smoke and not losing any oil. I have no idea and really need some help any thoughts or advice will be greatly appreciated thanks

First I would try loosening or removing the gas cap and see if the problem continues. If the vent in the gas cap does not work the engine draws a vacuum in the fuel tank until it cannot draw fuel.

Is the oil filter literally smoking?

Is the top of the engine all in place, the big plastic cover, the fan on the flywheel, the metal covers over the cylinder, etc?

Not literally just very hot to the touch. The top covers are complete we bought it brand new and this is the first problems we have tun into.

When you said you put in a new filter, was that an air filter or a fuel filter. If fuel filter was it red or white? Obviously your problem sounds like a fuel restriction somewhere. Also, does your tractor have a fuel pump?

Filter is clear and I replaced both the air and fuel filters. I agree fuel related but I can't seem to figure out what it.is I am considering taking the fuel filter out and running just a straight line to see if it is the filter. But it is so weird how the oil gets so hot and that it restarts immediately after it stalls. Very strange

Try without the filter just to see. The oil will get very very hot in a small air cooled engine. Over 300 degrees. I would check the cooling fins on the cylinders to see if grass clippings are clogging them. If it is getting hotter than it should be, it could be vapor locking the fuel lines or carburetor, or messing with the coils, or ??? If it is overheating, you are likely to drop a valve seat or guide, possibly ruining the engine, so it's worth checking to be sure the cooling fins are clear.

Fins are clear of debris but I will try the filter and let you all know if it stops raining. Thanks for your suggestions I appreciate it

So I have found the problem. The anti backfire solenoid on the bottom of the carb is the problem. I jammed it with a toothpick and it never stalled. Does anyone know the part number or even better can I just remove it and put a plug in it to avoid this problem in the future. Thanks for all your help in getting me straightened out.

If it has a little needle on it, you can just clip the needle end off.
