I have the unfortunate situation where my RV-12 is hangared in North Georgia while my job's in South Florida. I try to get up there once a month for long weekends to do some flying. When I store the plane for a month or two at a time, I fill the tank with 92 octane non-ethanol mogas, pull up the fuel shutoff valve, start the engine, and run it until it stops. Herein lies my problem.
It seems that invariably, one carb runs dry before the other as the engine continues to run on two cylinders until it finally quits. During this two-cylinder run as the second carb is running dry (less than 10 seconds) the engine shakes violently. I'm concerned that all of this rough running and shaking is going to rattle something loose up there under the hood.
Does anyone else have a similar experience, or know of a better way to drain the carbs for long-term storage?
