1995 Yamaha 250 that misses at just off idle to about half throttle.

[-HIC-]

Hi folks! I have a 1995 Yamaha 250 that misses at just off idle to about half throttle. Starts and idles great and runs great after a little over half throttle. Any ideas what the problem might be?

I have a 2002 Yamaha 225 3.1L on a 21 Hewes flats boat and mine does the same thing. Use only Yamaha Lube!!
