Not sure how long you ran it in the engine. Amount of time run and at what RPM would make a difference. I would call that going towards the lean side just a little.. Is this a twin? if so how does the other look in comparison?

You are on the lean side. I agree with Tim, give it some more fuel.
I would also be checking the air filter and filter housing. Either the engine is burning a bit of oil, or it is getting a bit of dirty air. Looks to me like it's getting dirty air. How loose is the throttle shaft? A loose throttle shaft will make it run lean, and suck in dirty air.

You must not have seen post #7. It's a new carburetor. It now has a new shut off valve, filter, fuel line, air filter and pre-filter, and spark plug. That plug was in it with a carburetor with a worn throttle shaft and the old air filter.

Yup, put a new plug in it. 3-4 hours of regular use and have another look

I just put a new plug in it. This is a 1250 with a Kohler K-301 AQS engine.

Yes, I need to mow but we had a downpour today. Hope it dries off enough tomorrow. It takes me two hours to mow. We'll see.

I did miss that.
I bet that's why the plug looks like that then....

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.
