Normal
You are so right! That was me a couple summers ago. The boat I bought which was supposedly ready to go with a full tank of fuel, having been used days before was kind of a turd. The tank was full of little gray boogers, I guess from ethanol? Think the seller put new gas in with the old. Anyhow ******* me had to clean that carb several times before figuring it out. Something else I figured out. ALWAYS put an inline filter on it. Which I did with this one, so I don't think I likely sucked anything in unless it got sucked in the carb mouth.
