And , when you run out of that junk carb cleaner , buy brake cleaner instead .
Brake cleaner cleans better , leaves no residue , doesn't want to eat rubber type bits and is very useful for/on a lot of other things .
I haven't bought carb cleaner in about 30 years or more .
I buy the flammable type as it seems to do the best job and it works as starting fluid , if you're quick enough . ;)
