CRC Clean-R-Carb Carburetor Cleaner (50 State Formula), 12 Wt Oz

not a lot of success with it I used it I had to end up taking the curb apart from my lawn mower really wasn't a lot in there the carburetor cleaners should be able to handle it but it did not

Used it to clean out all the lines, clean the carb, then prime the spark plug. My little 50 which hadn’t been started in 3 years cranked right over. Good stuff.

Bought as a gift, he uses it frequently so I am sure it delivers adequetly.
