2082 boiling fuel in carburator?
Hey guys I'm having a very sudden issue with my cub cadet 2082.
It has had a Magnum 18 engine installed into it about 6 years ago from the PO. My issue just started last week and I'm a bit lost. I can mow with it for about 15-20 min and then it will start to die. Only way to sometimes keep it running to limp back to the garage is to pull the choke out all the way. Still then it just diesels, blows some black smoke and mostly dies. I'm getting good spark on both cylinders during this as I've checked it with my in-line spark tester. I initially thought it to be a faulty pulse fuel pump as it seemed to be starving for fuel. However, its definitely getting furl. What I did notice today when I pulled off my air filter was a bit of fuel in the carb under the air filter and a crackle pop noise coming from the carb. Put a stethoscope to the bowl and it sounds like the fuel is boiling like crazy giving me a vapor lock. I pulled the carb and pulled the bowl to find a lot of rust in the bowl. Cleaned the bowl out, pulled the high idle needle and cleaned everything the best I could. Reassembled it and yet again after a few min it goes from running WOT to dying. Thought maybe the carb needed adjusted. Closed all the adjustment screws and backed them back out 1-3/8 turn as per the cub cadet manual. I can turn the adjustment screws for both high and idle in and out and barely get any engine rpm change. I'm meaning I can turn the screws in and out 4-5 turns and engine doesnt seem to change. Intake manifold right after the carb is cold and sweating but I'm still getting boiling sounds and an occasional white smoke coming from the carb. Any suggestions?

I can think of two issues. (A) It is time to pull the engine, then pull the Engine Air Duct shrouds off exposing the back or flywheel portion of the engine. I am guessing it needs a massive cleaning. (B) Pull the carb, take it aparts, and do a thorough cleaning.
Once the engine is clean and moving the correct amount of air, along with a clean and properly adjusted Carb, I going to say, it will run better.

R Bedel,
The engine is free and flowing massive amounts of air. I'm very big on blowing it out after each use. I actually took all the tin off the other day thinking it must be getting to hot. However, IR reads about 220°-335° around the whole engine. I finally got it to run but I have the left tin off and the hood and left plastic off. I dont know if it will start boiling again if I put everything back on. I had to get my yard done!

The "heat" is coming from somewhere.

If you keep overheating it, you will kill it.

You may be blowing it out as best you can after each use but if there’s any sort of oil leak from the crank seal even the smallest seepage it will gunk up all the fins where you can’t get to or see. It is an older Magnum after all. I would do as suggested to be on the safe side.

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.
