Any ideas? The air filter is clean and it has a new spark plug. It's got 10,310 miles on it. It starts beautifully.
probably right on the carb. as a big believer in better living through chemistry, i'd run some fuel system cleaner in a couple tanks before i started tearing things apart.
could be funky gas, too. i've had a couple suspect tanks in the last year or two.
