Default 2135 vapor lock

My friend and neighbor has a 2135 that runs for about 30 minutes, dies, then needs to be cooled down and it'll start and run again. It has the 13HP Kohler and is a 1996.

When I looked into the "runs for awhile and dies" kinds of issues I came across the coil as maybe being bad, and that was replaced but it still dies. The other issue is vapor lock. When it shut off this last time, he opened the gas cap but didn't hear any suction. We had cleaned the block off, new air filter and the tractor only has about 200 hours on it. He also tried running it without the sides on, and it didn't help.

It does a sort of sputtering dieing thing, and I can see the fuel filter go empty when it dies, but it died once after starting it again and the fuel filter was full, so I'm not sure if that means anything.

I was thinking vapor lock or maybe a vacuum leak? He's had this one for 3-4 years and its only started doing it this year, so I was thinking maybe a vacuum leak developed somewhere but at 200 hours it seems like a short time to get a bad gasket.

I tend to ramble, but the question is what can be done about vapor lock? Would moving the metal fuel line away from the block be a good idea and maybe routing it around the outside of the plastic flywheel guard? Or is it more likely a vacuum leak and without gauges how might one figure out if its vapor lock or a leak?

Default 2135

Does it have a fuel pump on it, if so maybe it is something with it.

If the fuel line from the tank is original I'd replace it. I've seen a lot of it about that age going bad, it collapses inside.

Make sure your fuel pump is pushing fuel. There mounted on the right hand side(passenger) of the block, down low. Remove the side cover and you should see it. Mine was starting hard for a long time and then finally one day sputtered, stalled and wouldn't restart. I replaced mine with an electric pump.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
