The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
BK is correct. You can't tell how clean the carbs are unless you drop the bowls off the carbs and inspect the passages in the carb body. Dried/old fuel tends to settle at the bottom of the bowls and can clog/restrict the high speeds jets. You can't see any potential problems by looking through the carb throats.
