Narrative:

Had fuel when departed ohio, due visual check. The gauges indicated, 1/2 tank in left tank and 3/4 in right tank. Burned all fuel in left tank and switch to right. Upon crossing over altoona airport to enter pattern the engine started running rough. I switched tanks, turned on pumps, increased mixture and informed unicom of problem and requested to land. Engine continued to run rough till park and looked in gas tank to see, no fuel with indication of 1/4 tank on right tank. I relied on my fuel indications and not on judgement. I should have topped off and will before any flight again.
