Default 782 getting hot
Hey guys, I have been busy using my 782 I picked up last fall.
Recently it started to surge after it gets hot.
I will mow for awhile and it it it start surging until it dies.
Then I can restart it and get another 10 mins out of it until it dies again.
I have found if I let it cool off it will run great.

A few days ago I decided to take the side panels off to see it that would help with the heat.
Sure enough I haven't had a problem since.
What gives?
What's the surging from? Vapor lock?
How do I get that to go away so I can put the side panels back on and mow on a hot day?

The blower housing on the engine could possibly be filled with mouse nest.

Yep, give 'er a good blowdown. They need to have a lot of airflow to stay cool. Hopefully that's all it is.

My 782 acted very similar. Dying when it would get hot, then start back up when it cooled off. When I tried to start it when it was hot, it didn't have any spark.

I replaced the coil. I haven't had any issues since.

I never said I wasn't going to adjust it. I'll dig into it before I go out next.
I'll blow it all out, power wash it again( to ensure it's clean in there), and adjust the carb some.
Not a big deal.

I was just making the statement that I wouldn't mind a few extra horses and fuel injection.
If the cub dies, it will give me a good reason to toss a paint job, new tires and some extra power at it.

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.
