Did you take it apart to clean it?

I doubt that it would. Spraying an assembled carb with carb cleaner does NOTHING.

I had the exact problem multiple times on 1872s. I cleaned several carbs rebuilt a few with varied results. The best results I got was taking the carb to the local dealer and having it rebuilt. 15 minutes off 15 minutes on and $60 later all was good.

I had a Mercury outboard that sat 5 years with gas in the carb. Had the dealer ( my first motor boat)"rebuild" the carb.. slightly better. I talked to my snowmobile mechanic, and he told me to take apart the carb and boil it in vinegar and water for about 30 minutes. FIXED IT. He said he gets 100 carbs a year that need the same fix. You can spray them all you want with carb cleaner, but if you want to get every small nook and cranny clean, that's how he does it. Just a thought. Don

I had the same problem with my 1872. I use one of the 1 gallon cans with 3 quarts of solvent and the basket. It worked and I have not had any more trouble.


Here is what I used:

That's the stuff
Soak it for a couple hours, or a few days, wash it out and use compressed air, rebuild. = clean carb

I read these threads all the time and I don't understand it. If the carb has been sitting for years and has dried up crud and rust in it, I'll soak it. If it's off a runner that suddenly "gunked up", or one that has ran in the distant past (6mo-1yr) and has gas in it, I just pull it apart and rebuild. Never had any issues getting one cleaned out of the first try.

I've saved two crusty cruddy carbs on the stove with vinegar and water. Then add sugar,pickles and peppers. I used to have a 115 merc, inline 6 with 3 carbs. Mike

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.
