Ok so I am winterizing the boat for my first time (next year I do the stabilizer first). <br /><br />I have already done the wheel bearings however I had not ran the engine with stabilizer in the tank, oops to late to put back in the water. I have now added the stabilizer and driven around the neighborhood and local school speed bumps for around 30 minutes (to shake up the new mixture). <br /><br />Anyone have any idea on how long I need to idle this GM 4.3 two barrel carb to burn out the gas in the carburetor bowl, quart sized fuel filter and the fuel line to be sure I get stabilizer into the carburetor?<br /><br />Anyone know a formula for how much gas a GM 4.3 or any engine for that matter, burns per minute?
