2072 carburetor problems?
 

having some issues with my 2072...was mowing today everything was doin fine for about a half hour, then the motor started choking down...I shut it off, started it again ran for maybe 10 minutes then the same problem..this problem continued with no specific run time...may be 2 minutes might be 15......sprayed the carb down with carb cleaner that didn't seem to help at all..also no adjustments that I made to carb changed the problem....time for a rebuild? any other ideas? thanks for your time

Did you take it apart to clean it?

no didn't get that far yet..jumped on the 1810 to finish cutting then got to dark to work on it

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


This would be the next step.

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:beerchug:
Soak it for a couple hours, or a few days, wash it out and use compressed air, rebuild. = clean carb:beerchug:

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. :Unknown:

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:biggrin2:
