Default 1864 Hot No Start Issue
Very seldom do I ever start my tractor after mowing, I just finish, clean it up and park it. Today I had to stop mowing after about 20 minutes, then when I went to start it after it sat for about 20 minutes, it wouldn't start.

Cranked with no problem but wouldn't fire. I was pretty sure it was a fuel problem since the coils are fairly new and it wouldn't even run on one cylinder. Took off the air cleaner, put some fuel in the carb and it started and ran.

Seemed like 'vapor lock' issues of years past but not sure what would cause this?

Anyone ever seen this issue?

Thanks

I currently have a 1864 with the same problem. I have not tried to repair it yet but it is on my to do list. I am thinking it might be an intake gasket but I am just guessing,

Interesting. My first thought was some kind of 'vapor lock' tied to the fuel pump.

The Kohler Engine has a Fuel Solenoid. I would check that.

Checked it out and could hear the plunger clicking when I turned the key. I know that doesn't mean it was working when it was hot but it's not dead.

Regarding removal of the solenoid, I can see there is no access to the screws so I'm guessing the carb has to be removed? Just 2 bolts for the carb?

I saw it mentioned several times here to remove the solenoid and cut off the plunger but I decided against that for now since it starts up real easy when it's cold. Should it ever die at least I'll know what I'm up against.

Look to see if you have restricted airflow around cooling fins....

Checked that and made sure by hitting the area with compressed air.

Thanks.

You mentioned that the coils are "fairly new" but new stuff goes bad too.
Since it is heat related and you havn't said anything about checking for spark when it won't start,
I'd suggest picking up one of these testers, cheap and available everywhere, to eliminate that possibility.

Ironman, have we become so soft that we no longer just hold onto the blade of a screwdriver stuck into the plug boot?

Any us of that ran the old English motorcycles still have hair standing straight out on our arms. "Ape hanger" handle bars were invented to give the armpit hairs a chance to cool and settle down after a roadside spark check. A couple of condensers and a ziner diode were standard in the saddle bag.

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.
